Is the PowerVR 540 just to slow for this screen?

Hello,
i am wondering, i have used my Galaxy Nexus for some time now at stock GPU clock and it was not a pleasant experience. I came from a device with the PowerVR540 but only 800x480 (Nexus S).
This phone had no trouble to keep up with rendering stuff, it was fast and (nearly) everything was fluent.
The Galaxy Nexus on the other hand can't keep up with frames in many stock apps at landscape and especially not in the browser..you can see that it drops below the 27 fp/s minimum for the human eye (no discussion about this 27 please).
I have now overclocked my GPU from 307 to 512 mhz, the result: It's like my Nexus S, everything (well, not everything) is sooo fast and it works great.
Is the PowerVR540 in the Galaxy Nexus just to slow for it's 1280x720 screen?

This has been asked many times, the gpu us actually one of the better chips out there. For your apps slowing down all I suggest is updating all your apps to latest version and make sure your running the latest version of your rom if your using Google stock or a custom rom. Youl also find over clocking your gpu will just use more battery for small gain. It was explained better in one if the custom kernel threads. If you ask my opinion Google knows best what hardware to use in their flag ship devices and now I'm running 4.0.4 stock rooted my phone is absolutely perfect.

I don't know, Google doesn't seem to know their hardware...my apps are up to date but my problems are with stock apps. I have used 2 GN and it was the same on both...lags, lags, lags...maybe some don't notice them (or just ignore them) but it's a horrible experience for me...i am just wondering why this phone isn't using a PowerVR543MP2...

Are you on a custom rom or stock? Stock 4.0.4 rooted has solved a lot of the small lags I found, try updating to it is my advice.

Stock 4.0.4...it's just that my Nexus S was somehow faster then the Galaxy Nexus...i expect better performance when i upgrade...not the other way around

Nexus s has a lot less pixels to push, the resolution is no where near as high so that would be my guess.

My Galaxy Nexus hardware is crap; help me work around it!

OK, the long and short of it is - this GNexus is unstable even at stock clock speeds. It reboots periodically (this is true on stock JB and CM10).
On CM10, I've managed to get logcats (which reveal nothing consistent), but more usefully (maybe) is last_kmesg. It tells me:
Unhandled fault: imprecise external abort
So - can somebody tell me a way to make this device more stable? I am pondering underclocking. Or changing the governor. Or changing the voltage (although, I don't know which way to go: up or down!).
I guess I'm looking for whatever tricks overclockers would use to increase stability - except, leaving it at the stock clock speed

Well. If you get reboots , increase the voltages by 25 mv. See if that helps.
Sent from my trasbeaned Galaxy Nexus.

The lower voltages allow less use of battery, but if they are too low (reboot, freeze), you should increase it a little

If you're having reboot issues even on stock, it sounds like a hardware issue and needs to be replaced.

I don't have 400 bucks lying around, hence my desire for a way to make this one just suck less
I'll try the voltage increase to see if that improves anything. Is there a recommended app for doing this?

Cm10 has the option in "performance" settings to change your voltages

Switch to the Team EOS rom (nightly or stable) , use the latest Franco Kernel(latest) with gpu at 384 and finally underclock to 1ghz instead of the stock 1.2. I am currently using the dyninteractive governor.
I experience less heat, way fewer reboots, better 4g, things are still snappy and you can still speed up animations to .5x the speed in developer options. Oh and the extra battery life is nice.
Someone also recommended using only one band with WiFi. I use 2.4 only. It can be found in the advanced setting in wireless.

Manufacturer warranty, insurance. Your carrier should be willing to swap the phones out especially if you just got it. Running jbsourcery 2.3.6 and Franco milestone. I've had a total of 4 reboot period on this device since it was debuted.

It would reboot by itself when it became too warm. Franco's lastest 282 kernel seems to have solve this heat/self reboot issue for me. I can use 1.3 ghz without a problem. I couldn't do the stock 1.2ghz on the stock kernel without it rebooting by itself. It is also super smooth and fast.

Blurred graphics in NFS Most Wanted

I bought this game recently on sale and installed on my brand-new Nexus 7 (32GB with 3G). However, graphics seems blurred - like it was set for low quality, or prepared to run on lower resolution. That's strange, because all menus and main menu are normal. The problem is that there is no graphics settings in NFS. Is there any possibility of changing graphics to sharp? I'm running CyanogenMod 10.1 nightlies. On my Galaxy S3 (CyanogenMod 10) everything is OK - smooth with sharp edges.

Was thinking about purchasing it today but I'm not if this a reoccurring problem for people. Has this happened to anyone else?

What kernel are you running?
Try metalice A25 with the GPU clock at 666. Should fix it.
Sent from my Nexus 7

I'm not having any issues. I've heard people having issues with non-stock kernels with this game. That may be your problem.

I didn't install any custom kernel, it's running on CM one (screenshot attached). I prefer original CM kernel to custom ones. I'll try tweaking settings in performance tab.
EDIT: Nothing interesting in performance settings.

Yea I remember reading it has something g to do with the higher CPU max on custom kernels that makes the graphics like that.. I've only been able to have it right on bone stock from google even on stock cm I had the issue

But in CM kernel doesn't have overclocked frequencies, max one is 1300. What's more, cars in garage and before race are showed in full quality, nice and with sharp edges. After starting the race graphic becomes blurry.

No problems for me, it's always ran smooth. Running PA2.50 w/ franco.Kernel r25. No overclocked CPU or GPU

AFAIK, there is no franco kernel for 3G version and I doubt that version for non-cellular Nexus works with cellular one. Anyone knows what can be done to increase quality without changing ROM (CM 10.1) and kernel?
Sent from my Nexus 7 using Tapatalk HD

I downloaded it the other day but I've yet to play the game on mine. I use AOKP with the stock kernel, so hopefully I don't have these problems.
I just hate how it uses 2GB of space when the description only says it needs 550MB!

[App] Battery Core Live Wallpaper

Just released another live wallpaper. This wallpaper is tells how much battery you have left, voltage, temp and status. The spinning core will spin faster when you have full battery and slow down when your battery level gets lower. Also included are some particle effects. There's a few customization on the free version and more in the paid version. Its been optimized to use as little ram as possible and update cycles were slowed down to drain less battery. Tested on nexus 4, nexus 7, galaxy s2, galaxy s3 and lg g2x. Nexus 4 and Nexus 7 were my primary test devices so it should work pretty good on them. Check it out.
8-16-2013: Updated to allow users on the free version to get all features of the paid version by completing simple free offers. Download it for more info. Also, some bug fixes.

Well, I got bored. So I added in ability to change from Celsius to Fahrenheit. I just uploaded them so it should be available in a couple of hours.

Where is the setting, I couldn't find it.

In the battery text section. Its just a check box to switch to farhenheit or else its Celsius.

I updated the app. It should be available in a few hours. Thanks for all the feedback, compliments and complaints. If you have some cool core ideas that you'd like me to include, I could try that. Only catch is, I have to be able to create it myself....but I'll credit you in the app though.
New updates includes:
* Move text to top of battery core
* Cleaned up settings menu
* Adjust glow effect color on battery core(paid version only)
* Glow effect of battery core changes color on low battery, user sets low battery point

Just bought it, awesome lwp

Published another update. This time I think the 2 new cores, Core Type3 and Core Type 4 are pretty cool. Also added in some more particle shapes.

I added another update. Somehow, in my last update I got Core 2 mixed up with the Arc Reactor. Dont know it anyone noticed. There's been a lot of complaints about home screen lagging. So with this update, I hope to fix some of it.

App updated.

Love this LWP, reminds me of the Arc Reactor from the Iron Man suit.

[Q] Nexus 7 (2013) Overclocking

So, I was wondering if it is possible at all to overclock the Nexus 7 (2013). When I go to the app to overclock it (Yes, already rooted and installed busy box) I am unable to change max CPU's frequency higher than the default 1.5ghz. I also can't change the GPU's frequency over 400. Was wondering if there's like a limit to it or something. I was hoping I could overclock to 2ghz. Please help, thanks

Not to be mean or anything. But you really should not be overclocking your device at all when you don't even know what is required to over clock in the first place'. Let alone 2ghz.

Everybody has to start somewhere.
The kernel linked above should work fine. I would recommend backing up in TWRP/CWM before installing in case something goes wrong.

Why would you need to overclock this device? It already runs amazingly smooth with no lag whatsoever. What is it that you need the overclock for?

So let me get this right, you oc your CPU to 2ghz yet you use a battery saving (read low performance) CPU governor?

Intellidemand is (for me) the fastest and smoothest overall with decent battery life as well...

I haven't found one game that has made this tab lag yet. Maybe next year there will be a reason to over clock the n7 2013. It's a great device that just purrs.

Well Beach Buggy Blitz would lag at times when there was a lot on screen (like the cave full of coins would kill my fps), This was on stock Kitkat, with custom kernels works fine with no drop in fps.
On a funny side note, cm11 runs everything lag free without needing oc or custom kernels, so maybe it's the stock kernel that's crap

Nexus 7 frame drops
I have a Nexus 7 2gen and i hace notice a frame drop playing Shadowgun Kik Kat 4.4.2. I was so frustraded that I was starting to dislike the nexus 7, but searching I found this threat and read a comment were said about installing a different kernel so I installed ElementalX 2.6, since then I haven't expirience any frame drop playing shadowgun I really enjoy it now, maybe is bad stock kernel. I hope this threat help others

The only game I've played that managed to drop my frames substantially that I would notice was Real Racing 3.
Now, I have CleanRom and ElementalX onboard but haven't played anything to test the performance. 2.1Ghz and GPU at 500Mhz.

I am currently using stock rom with elementax kernel, cpu @1,72ghz and gpu @450mhz. When i tried 2ghz oc, everything worked fine, but it got really hot while gaming. So i´m asking me how dangerous it is to use such high oc values in daily life. How much could it decrease the lifespan of the components?

We can only guess. Keep it at 2ghz, and let us know how long from now before your CPU is baked, then we'll all know for future reference.

Also there is an inductive charging coil on the inside for wireless charging some day when they come out with the chargers, sweet ****

Actually it is an underclocked snapdragon 600, but i didn't know that this cpu supports a clock speed until 1.9ghz (thought 1.7ghz would be standard clock). So i think up to 2ghz there shouldn't be any problems and it's okay for everyday use. I've also heard of some rumors that our nexus 7 2013 contains a "second choice" snapdragon 600 chipset, which didn't fullfill the predetermined requirements and that's why it was rebranded as an s4 pro... but this is really unimportant and just speculation.

omg you certainly shouldn't overclock it because the SOC architecture is designed to run at optimal clock speeds... by overclocking it, you might shorten the lifespan of your device and you might even damage it permanently as well
