SG2 and Hardware Acceleration

There's no denying that as it stands the SG2 is the fastest android smartphone out now. I don't own one but based on what i'm hearing its crazy fast. My question is with its speed (thanks 2 the dual-core processor) would it benefit from the hardware acceleration that comes with ICS?? Does the UI in this phone running as smooth as an iphone or the Samsung Galaxy Nexus without hardware acceleration? Or despite its speed does it occasionally still stutter in between screens from time to time or jumping in between apps??

It stutters because we don't have the Exynos. Still pretty badass overall, and hopefully ICS makes it even better.

It doesn't shutter cuz its not exynos. Those problem can be solved by touchscreen tweaks

You can truly fix any lag with good software. It's no different than a ps3 and xbox 360. The ps3 is more powerful but xbox 360 games are easier to program for. Why you think that all multi-platform games run better on the 360 than ps3. Most developers here have massive experience with qualcomm processor. Then with a exynos.

with the stock rom, it stutters from time to time, when you scroll through the apps list (people who say its just the same, either doesnt pay attention to details, haven't seen how smoother exynos versions run, or are in denial. period). from what ive been reading here, touchwiz is hardware accelerated on phones with exynos. and it is true that good software can fix this problem. i started using beastmod 1.0 rom 3 days ago, and the stuttering (while browsing through the apps list) went away. mostly because of the tweaks. and another thing is, its the smallest file sized rom for our sg2, so far. that means, less load. more free RAM. obviously it'll run faster. the trick is, keep more than 450mb+ RAM free, to keep it silky smooth. at least on my phone, it works.
but one thing for sure. hardware acceleration gives a very big advantage. imagine combining hardware acceleration with these dev's modded roms..
the only con part of the snapdragon is, it is running both cpu and gpu on a single bus lane, which causes more traffic, and can be easily bottlenecked. while the exynos has 2 dedicated lanes, one for the cpu and another for its gpu. giving more space to breathe and run processes smoother, separately. plus exynos' mali-400mp gpu has four cores.
the good side about the snapdragon is its power management. runs on battery much, much longer.
it all boils down to one thing. when ICS comes out, im counting on it to make our phones a lot smoother, not just on a few things that the exynos hardware accelerates, but overall.
people are saying our gpu is much faster, its just not utilized correctly (i dont know how much technically inclined, on the hardware side, those people are). but websites have a variety of benchmark/real world results showing how powerful the exynos gpu really is.
honestly, i really dont care if exynos' gpu is much better, i dont play crysis on my phone. as long as our phone's gpu deliver enough power to be as smooth as the exynos' with ICS, i'll be an even happier camper

i don't know how it's going to be when ICS arrives
but even know the phone feels sooooooo fluid, it's hard to imagine how much better it can get with HW accel
on the I9000 and nexus S it's a night and day difference when you have HW accel apps vs not

Why is the Nexus so laggy compared to other phones?

I mean the frames are just so slow when you press the app drawer button. I even have it rooted and tried different ROMS and kernals, but I'm beginning to think it is ICS itself. I had a Sensation that seemed like it was running at 60 FPS and it was just smooth. When people say that their Nexus phone is running "buttery smooth" I'm sure they're blind. After playing with my girl friends SGS2, I'm completely jealous of how smooth and snappy her phone is compared to mine.
So the question is, why the hell is Nexus or ICS so damn slow and choppy compared to other phones like the SGS2 and my old Sensation?

Its not...are you overclocked? That could cause stutteryness. Maybe you should try restarting he phone or clearing RAM? My phone is buttery smooth, faster than any other phone I've seen.

i hate to say this, but your either trolling or you have a broken phone.
out of every phone i've owned. (including the Sensation and the Galaxy Note) my GF's Nexus is by far the smoothest out of all of them. the closest one i've owned in 'smoothness' was the Note. followed by the Sensation. difference is the Sensation took 1.7GHz to get to anywhere near smooth. whereas the Note and the Nexus were/are bone stock.

For the 1st time you call the app drawer it could be a bit lag, but I can hardly observe that without this thread.

Maybe its your phone. Have you tried another one? My co-worker just got one and he also has occasional lag when he goes back and fourth from the app drawer to the home screen. He returned it, got another and he was able to duplicate the problem. I've had mine since day one and have never had any lag issues, and yes mine is "buttery smooth", and no I'm not blind. We figured it must be a bad batch.

My Galaxy Nexus is way smoother than my Galaxy S2.

my phone is smooth.

OP is nut. Sorry friend. I am unlocked rooted 4.0.4 no mods at all and this phone is fast as one could hope for.

You must have a software bug or something, my UI is easily hitting the 60fps mark and buttery smooth compared to all my previous android phones.

mines buttery smooth

Don't use LWP's.

I knew you guys would say stupid **** like this. No it's not OC and not I'm not trolling. I'm just f'in disappointed. To me it looks just choppy. It's not just my phone but all Nexus devices that I have seen.
It just feels like it's frame rate is low. If your looking at your home screen, you have some widgets and press the home button to fly back to the main screen, you can see the frames just drop. It's stupid.
It doesn't hold a candle to my old sensation or the sgs2 that I've played with.

Don't use live wallpapers. Aside from a few of the bundled ones, they're all made for 800x480, and even the optimized ones don't help the framerates.

No worries man, I know what you are talking about but its more to do with the Resolution of the Nexus's screen more than anything. Its pretty taxing on the phone to pull off the resolutions its rendering but it can tweaked to be pretty smooth and fast. The launcher on the Sensation is very optimized whereas the SGS2 is overly powerful that it can run pretty much anything at full blast due to the superior GPU on the SoC. Luckily our phone can run 2D graphics and calculations faster than any other phone on the market even being clocked at 1.2 Ghz.

The Galaxy Nexus, even with roms, is not as fast as the Exynos GSII

I have a GSM Galaxy Nexus and it has AOKP build 25 with Fugomod kernel on it and this thing still is laggy. I tried many different roms and kernels and it still lags. I'm pretty sure my GSII was faster.
Some people say they have a buttery smooth Nexus and I'm jealous of you because mine feels like a 700mhz single core phone with 256mb of ram.
What's the deal? Why is it lagging (stock keyboard, browsing, app drawer, etc)
And I'm not trying to "bash". I want to keep the phone but the slowness is frustrating.
UPDATE 2/27/11 - I wiped my phone and flashed the Apex 1.02 Rom and now the phone is really fast. Some occasional hiccups but not a big deal.
I'm a very happy GN owner now.

So nobody can state their Galaxy Nexus is laggy? If so then you're a troll? I don't understand that logic.

I'm so sick of people comparing the galaxy nexus to the gs2. They are different classes of phones. The gs2 is running on a screen with a much lower resolution and an old version of android. If I take my PC which runs any game great on my 19" monitor and then connect it to my 46" HDTV the same games run laggy because my video card is working much harder to run the game at the higher resolution. Also if I play a game on windows xp and then play the same game on windows 7 the game tends to run slower because as operating systems evolve they tend to need more resources and also add new enhancements that add more strain on the hardware. I'm sure you can put android 4.0 on a HTC dream but will it run well? Not a chance because android 4.0 uses more juice then android 1.5 that the dream came with. I bet if you could install android 2.3 on the galaxy nexus it would fly like a bat out of hell.

That is so far outside the norm that you are either trolling, have a defective device or flashed and did something so screwed up that its messing with your device. So either:
1. Do a complete wipe, including formatting data, cache, dalvik and system. Install AOKP, gaaps with trinity kernel (basic one for all devices). Reboot. Download auto start manager and kill anything like maps or talk that you don't want running at startup. Go into settings and set cpu to 1.2, 400mhz with on demand or performance scaling. Set on boot checked. Reboot. Then tell me the phone is slow.
2. Don't use live wall paper. Most of them are not optimized for ICS
3. Return your device and get another one its broken.

My laptop is faster than your GSII.

because google knows this is already powerful enough and the only place that it would make a difference is in benchmarks. Remember the nexus is the reference phone the developers are supposed to base their applications on. So in theory all app should run perfectly on all nexus devices. Basically any app made in 2012 should run perfectly on this phone. Think of it this way this is the minimum hardware requirements for apps and if a manufacturer goes beyond the specs its all gravy basically bragging rights but realistically this device has more than enough power to handle what google intended it for.

I'll play since I've recently made the jump as well and I think I'm coming in with an "unbiased" opinion. Keep in mind I'm much happier with my GN than I was with my I9100, which I'm also keeping at least until kernel source is released for ICS. Using CM9 on the Nexus and using CM9 on the SGSII, no comparison for me, Nexus wins, hands down as far as fluidity and feel goes, ignoring the fact that so many things still don't work on the SGSII.
There are ever so slight cpu and gpu advantages that I've noticed on the SGSII. Very occasionally might be felt as a lag or stutter. For the most part however I find the GN "smoother" over all. Alternative launchers (Nova) lag for me on the GN going in/out of the app drawer, but removing widgets from the app drawer cured that. I may have to wait an extra second, maybe two, for the desktop to be fully fluid following a boot. I've never experienced keyboard lag, or alike.
In the end however, I didn't buy the GN because I thought it would kill the SGSII performance wise and the specs didn't lead me to believe that would be the case. A couple of non-performance or Android related things I really appreciate are the feel of the phone in my hand, and the action of the buttons. What I used to jokingly refer to as the "panty liner shape" of the phone is comfortable in my pocket.
It might take some more kernel experimenting on your part to find one that feels good for you. When I was on AOKP I found Leankernel to be absolutely buttery. Slight cpu/gpu advantages aside, I feel that the GN is the better phone overall and it's still a bloody fast unit, and my next device will be a Nexus as well. I'd say 95% of the time the phone feels as fast, and potentially more fluid, than my old phone.

So this year we're gonna have all these new quad core phones coming out which is great, but when the new version of android comes out we will get it right away and all those new quad core phones will be waiting up to a year to get it and by then the new version of android will be out yet again. You don't get a nexus phone for it's powerful processor look for it support and long term commitment. I had 5 android phones in the last year and I will never get anything other then a nexus because of all the stress I had trying to get updates for my other phones. My last phone the optimus 3 d was a very good phone butwe just got gingerbread a few weeks ago and lg is saying we will get ice cream sandwich in the third quarter f 2012. By then my nexus phone will probably have the new version of android. And I'm sure that lg will be dropping support for that phone because they'll have a new 1 out. But my nexus phone will most likely be supported through 2013.

The OMAP SoC in the Galaxy Nexus is superior to that in the GS2. It was the best SoC available for the release date they wanted.
Maybe the Exynos can benchmark higher but as Fancisco pointed out
"Most GPU workloads on 4460 with a 720p screen are limited by the
memory bandwidth, not the GPU computation ability"
I am fairly sure the OMAP SoC we have has a much higher memory bandwidth than the GS2 ^.^

Not quite. Not sure about the exact memory channel speed but they both utilize same exact memory setup dual channel LPDDR2
OMAP was the SoC that Google chose
It's essentially a terrible choice with grossly outdated gpu in a platform where GPU will start to drive every day operation
This isn't to say that Mali400MP setup is the greatest in the GPU choice but eventhough it's inefficient, it's able to push through with raw power
I may get a bit of flake for this but Nexus does micro-stutter in some instances in places like the stock app drawer (this is addressed with nova launcher but question was does the GNex stutter).
I wouldn't blame the slight lagginess or stutters on the hardware just yet seeing how ICS is still fairly new and there is also the issue with maturity of apps running ICS.

Thanks guys for your responses. I'm not trying to be a pain; just annoyed that my old phone felt smoother.
I installed Apex rom and so far it feels very fast so hopefully it will stay this way. I kept the kernel that was packaged with the rom.
Another reason I thought it was slow was because I would type on the desktop site of XDA. Using the app doesn't cause the keyboard lag. It still is strange why the keyboard would lag like that while posting on XDA.

Galaxy nexus faster than galaxy s2 & sony xperia s?

I saw the review of the ics gs2 and at the end i saw some benchmarks... on the cpu side the nexus seems to hold its own againts the xperia s which on paper has a faster cpu snapdragon 3 1.5Ghz compare to omap 4460 1.2.. also gs2 seems to be slightly slower in the cpu benchmarks compared to Gnex....

gs2 is surely faster on graphics (it has a more advanced gpu, though clocked slower), but it has less screen resolution.
on the cpu side they should be pretty equivalent.
i don't know about the xperia.

In real world usage my SGS2 was significantly faster than my GNEX in every department barring taking a picture.

I wouldn't trust that much on benchmarks.
What matters is how polished the stock roms are for each device.
I love how the nexus keep running smooth even after installing a ton of apps, never experienced the same with other devices.

While the MSM8260 (Xperia S) is clocked faster, it has a single channel memory interface while the TI-OMAP 4460 (Galaxy Nexus) has a dual channel interface.
Also beware of those benchmark tools. Most of them are crap. For example they use the phone's resolution to do 2D/3D benchmark which is not a fair way to compare.

Was it significantly faster in getting updates?

Benchmarks are cool in a sense, but I've started ignoring them. My GNex has been really fast, even with Window and Transition Animations. There are exceptions. I ABUSE my Android devices with heat (nature of my work environment). When it gets hot, it does lag. At the same time, the CPU is also scaling itself back. When I get the rare lock'n'reboot it's pretty much always due to heat. Typically, flinging through settings, menus, apps, etc is really fast. Right now I have wireless tethering on and I'm streaming audio through Tune In. My battery is almost 120F. It's slower. Any device would be. If I pick up my Nook running CM7, it'll be slower right now too due to heat.
Benchmarks mean very little to me now. I mean, what's the point? What are you gonna do, brag about a superficial number? Get it engraved on your belt buckle? I think they can be an indication of certain aspects of a device, but benchmarks do not necessarily tell someone what kind of user experience that device is going to provide.
If I pick up my favorite device and I can do what I want to do quickly and smoothly then I'm fine with it. Even OCing a high end device is something I've never been able to tell a difference with. Now my Nook, yeah, an overclock worked wonders. On the GNex, pish, nah. Remember too, a lot of these 1.5Ghz devices are pushing a bloated framework too. Beyond that, ICS is going to have it's own limitations, especially when it has bugs to get worked out.
It can kinda be like cramming 16GB's of Ram into a PC running 32 bit Windows 7. The hardware addition is irrelevant and while you can brag about 16 gigs of ram to all of your friends, it's a pointless feature of your system.

one thing for sure is that software optimization means much more than hardware differences between those 3 phones.
thus, it depends on what you're going to run: stock, aosp, cyanogen, miui? that's the question.

We've had a pretty stable CM9 for the i9100 for quite a while now. But it still can't compare to the Galaxy Nexus....can't wait for mine to come

Just swapped over from the t989 gs2. The nexus is much smoother. We were always telling ourselves that our phones were better because of the supposedly better hardware... There were many threads Lol. Now that I have it I can see the experience doesn't even compare. Never buying anything touchwiz again

[Q] Why is the performance so poor?

I don't understand how a phone so powerful can run so poorly. Often times it may take up to 5 seconds to respond to input and is extremely laggy. My friends iPhone 4 is more responsive and it is kind of embarrassing when I am always talking so highly of Android devices, and a 2 year device with incredibly inferior specs is outperforming a brand new high-end phone. There also seems to be an enormous lack of development. I am really starting to regret purchasing this phone.

I agree that G3 performance is bad. Its because the system in chip had to draw all the extra pixels of a QHD display. It causes lag and slowness everywhere.
The QHD display needs a more powerful system on chip.

Its got nothing to do with the QHD screen. The processor is more than capable of rendering QHD in 2D, even 4K wouldnt be a problem.
The problem is LG have very badly optimised the software. The latest revisions are much much faster, Im using v10J and everything is instant. We went through the same problems with the G2.

I've seen it happen on old phones of mine that tried to render 1080 but struggled. You get the stutter effect and frame rate dropping because it can't draw it quickly enough. This is a good comparison video too of the more powerful 805 chip Vs the 801 chip

I've seen it happen on old phones of mine that tried to render 1080 but struggled. You get the stutter effect and frame rate dropping because it can't draw it quickly enough. This is a good comparison video too of the more powerful 805 chip Vs the 801 chip

Clearly thats not the case since I have absolutely zero lag. Its a fact that the GPU isnt stressed in 2D by the QHD, it doesnt even throttle past 330mhz. The 801 is rated for 4K, and only then limited by bandwidth rather than raw power.
Its all about the LG software. It will improve.

I have zero lag with my processor downclocked to 1.5ghz and 200 mhz GPU
So all this QHD resolution causing lag is complete BS and trolling.

Have to disagree,I see no improvement with 10j. Its very obvious the 801 is maxed out.

This chip is not maxed out at all, let's not spread false information please. LG needs to optimize the software for the phone to run correctly. I have enabled 60fps on my phone, and the thing flies now. No lag while scrolling, or while gamingto speak of. The chip has no problems with the resolution.
The thing with Iphone is the way it's set up, Android has more things working in the background eating up ram/etc, that's why optimization is so important. Put an 801 chip into the Iphone, which has MUCH less things running in the background by default, and I guarantee you that the phone will run much faster than with the A7 chip.
Also, rogue apps that are not optimized correctly can also cause serious lag. I recently had the HTC One M8, which ran beautifully, until I downloaded a rogue app that was eating up ram when not in use, and my phone was lagging like crazy.
So it's not really fair to compare android with ios's speed, because all Iphone devices work the same way, and use the same chip. While on Android, there are many factors and apps that can interfere with the OS. Any true Android fan should know how these things work..you can customize the phone to your liking, but you also have to deal with rogue apps and ram issues sometimes.

Have to agree that the 801 struggles with 2k, use a 1080 801 flagship and you'll see the difference. The frame rate on some games is poor in the G3 compared to 1080 801 phones and that's nothing to do with software. The QHD is also power hungry and runs hotter and thermal throttles the CPU more.

Exactly, this chip is more then capable of running the high resolution on the G3. LG should have taken the time to calibrate the software to run better, but the newer updates going around are based off of the info here from XDA users.The default battery saving technique to dynamically adjust the fps/etc only saves a little more batter, but is not worth the tradeoff of a stuttering device. LG should have put in a bigger battery and increased the phone size a little instead of setting up the phone the way it currently is. People are too obsessed with thin phones now-a-days, I prefer a little bulk with MUCH better battery life!

Also, just to add on to the info that the 801 cannot handle the 2K resolution, which is false..I had the HTC One M8, which oddly stuttered like crazy when playing Asphalt 8, and a few other highly graphical games, but ran smooth as butter when scrolling through apps/etc. However, my G3 has Zero problems now running the same games. So clearly, it's more at play than just the 801. It's more about optimization/etc.

I have pretty much zero lag, the only stutter I see is when pulling down the notification bar, but that happens literally every time I do it. Anybody experiencing the same? Rooted 32gb D855 10g.

I had that happen to me every now and then, until I switched from Dalvik to ART. Now I have zero lag when using the notification bar. Try that and see if it helps.

Thanks, but I'm using Xposed framework and as far as I know, it's not ART compatible yet :/ I'll keep it ind mind, though.

@MRCANNADY how can i enable the 60fps? i read about some people saying this but i didnt find anything about how to do this, can you help me?
sorry about my english..brazilian here

To give you an idea of the advances LG will likely make I recently flashed my G2 back to the original ROM. It was terrible, laggy, jittery, horrible camera lag. I then updated to the latest. Smooth, lag free, faster camera, totally reliable. This will happen for the G3 to.
QHD has nothing to do with the issues at all. Its quite clear LG released this phone in almost a panic about heat and battery life, with so many unnecessary measures taken. I disabled quite a lot of them and its smooth and the battery lasts longer than any phone ive had before, even my G2. I wonder if half the screens issues are due to LG undervolting it. Most mods for other devices undervolt the screen to save power, I want to try the opposite.

Oh yes, it's not compatible as of now. ART really does make a difference in how the phone works though. It's actually the first time that I have seen how beneficial ART is. Question, do you have any widgets in your notification shade/etc? You could also try using the Nova launcher and see if that helps.

Hello there
Follow the instructions below. Also, scroll down to Dynamic LCD refresh On/Off, and select disable. Then under Fixed FPS test, select 60FPS, reboot and enjoy!

The problem is LG have very badly optimised the software. The latest revisions are much much faster, Im using v10J and everything is instant. We went through the same problems with the G2.

So what about non d855 users. I have the T mobile variant and it seems we are waiting on Android L for an update as there hasnt been any incremental performance updates. I agree the software is not all it could be.

I use Nova launcher and don't see any lag.
When I was using the stock launcher, I thought that I would see some delay here and there, But I wasn't really sure if it was the phone or me believing what other people were writing.
But I did use the settings in the linked post and it seemed to make the stock launcher much faster. I do not know if it will affect your issue.
