Is the browser not GPU accelerated? Big boy like Tegra 3 should make short work of CSS transitions and animations but my speed is no better and animations no smoother than on a 2 year old android 2.x phone.
Have you tried checking the box for 2d gpu acceleration in development settings? It seems to have improved mine.
Edit:
Scratch that, the box won't stay ticked, .or sure it does anything now.
Check this out though:

I dont know if this got discussed already, but I just used the force 2d acceleration feature in the developer menu and hat a GREAT increase in perfomance, specialy in image heavy applications.
If you dont know this already test it, if you know it let us know
Some feedback on battery perfomance somebody?
You'll find some apps don't work too good with it enabled though.

If you use any type of comic book reader, you will be happy by turning on 2d acceleration. went from horrible 2fps choppy crap to buttery smooth.

bah seriously.. someone needs to write up a sticky for this kind of thing. Developer Options are not meant for regular users. There's no reason to enable them unless you specifically need to.
A few reasons why you don't want to enable it
- some apps don't handle this well and will result in everything from poor performance, weird graphical glitches, or even stop the app from loading at all
- there is actually considerable memory overhead to GPU acceleration (8MB vs 2MB). So you're really just making your multi-tasking situation worse.
Just wondering if someone could give me the final word on this as I've done some searches and have heard mixed things. Should this be ticked? Is the number of apps left out there that might malfunction with it enabled so low as to make it worthwhile to keep it on?
And does it really make a difference on a phone that's already so powerful?
Thanks.
I can't say definitively that Force GPU Rendering option on will improve things.
I would say it would but there where be some apps that may crash because of this option
Also if your phone is not on 1.29...then Force GPU Rendering will not stay on (my One X is still on 1.28 and when I tick Force GPU Rendering, when I leave the Developer Options screen the option is unticked)
Ice cream sandwhich phones should run gpu rendering.

Any more comments about force gpu rendering? And what about disable hw overlays? Does anyone about this? Someone somewhere said that it improved performance on his HOX.

so yeah, is it just a load of crap or does it actually work?
If you are on ICS you can make a nandroid backup and try it
I saw this today as well not sure whether to try it. Isn't it the same or similar to what we can choose in developers options to force GPU rendering? Maybe will try later when I have time as I cant complain with the speed that I'm getting from nikez jb p0.9

I am specifically wondering how will it work with gingerbread roms. I mean, it must be some kind of BS right? There's no way to force GPU rendering for UI in gingerbread, is there?
Joke of the day... classic!
Works on Mildwild 4.3. I don't have a launcher redraw anymore And it's not GPU rendering, it just removes the pathway to render on the CPU so the GPU does the graphics stuff

Basically everyone should be getting a placebo affect, i personally havent seen anyone provide evidence such as benchmarking surfaceflinger to prove the ui is smoother. The manufacturers by default select the gpu to render the ui which has a 0 1 on adreno200 and 0 0 on android thus its hw accelerated and not software accelerated
So what does that really do anyway ? Anyone notices really anything?
I don't trust benchmarks, they show incredibly inaccurate results (at least Antutu and Quadrant). Try run it twice on the same rom, one right next to another.
Well, no use from benchmark apps, but I tried it on MIUI rom with high resolution graphics settings for launcher. I definitely had lags issue with it without patch, especially with cube 3d screen transition effect. Now with it no lags at all, and I'm sure it's not a placebo.

Lol im not talking about regular benchmarking
I tried it with rom in signature and confirm that UI is smoother and also app like Facebook seems faster, like author is reporting in original thread.

Well I did actually just test it and it's obviously a load of crap and a waste of time. Can't believe I ACTUALLY was stupid enough to think that it'd work.

I don't think it's useless or stupid.... either 99% are having a placebo reaction with noticeable effects.. or they are having a reaction to a noticeable difference on their equipments.. I was also skeptic that would do anything.. I can't tell you what it is, but I do notice some differences.
I would say it works - somehow.
I use it on SpazeDogs ICS ROM and it gives a subjective performance boost - by feeling i wouldnt say that the FPS increased or something like that. But it feels smoother. Would call it "Project Butter light"

In developer options, what does enabling force gpu rendering do? Id like to know pros and cons.
I'm trying it right now cause I read this post, I think it makes things look better/smoother when using apps. Not too sure tho
Edit: just give it a google I just read a pretty good explanation of it I'll probably just leave it on now unless something gets weird but sounds like everything will be better with it on less lag smoother

I believe it forces the GPU (Graphics Processing Unit) to render things like transitions between menus, and what not.
Now I'm not sure if that's more power hungry, or bad for the device. But in my opinion, I believe this would be better than having the CPU render the transitions, because the GPU is designed for graphical rendering -- of course, there's the question of if the GPU sleeps while the phone isn't doing anything intense (gaming generally).
I hope that explains it!
I've installed all stock ROM's so far, tried Perseus kernel and Redpill kernel and some custom ROM's such as Android Revolution HD, HyperNote, Wicked, Omega etc.. All have some damn scrolling stutter when browsing though Contacts, Whatsapp contacts, Imo, etc, think of any scrolling list(browser scrolling webpages is not affected). Seems to be related to Samsung source code. Even the ROM's that tweak build.prop and use other ways of improving rendering using GPU acceleration still have the same scrolling fps drop. Going to developer options and turning all animations off and ticking 2d gpu rendering ON still don't make any difference.
Any, I mean ANY other operation such as browsing, gaming, etc is flawless.
Installing HyperDroid ROM (AOSP) fixes the stutter(but no motion, s-pen stuff etc I miss).
I want to use Samsung ROM source but all ROM's on XDA have this issue. Anyone encountered this silly problem?
PS: I always wipe and format all partitions before flashing.
I know Note 2 is a high-end device, but I never had this sort of LAG/stutter not even on 600MHz phones running 2.x Android.
I tried setting CPU on performance @ 1600MHz fixed frequency but scroll issue still the same as @ 200mhz. Seems not CPU related, and also not GPU related. Bad code optimisation I think.
Lol this is not iOS or WP, it's Android. Completely normal.

I agree with him. I had a desire z which was single core 800mhz and it never lagged. It is rather annoying considering the power of the device and not being able to perform simple tasks lag free. Maybe its something to do with project butter not working fully with the device?
since i dont have the whatsapp couldnt test that but my contacts show absolutely no lag, and i hate lags / stutters even mini micro ones. im on 4.1.2 btw
I have no lag in contacts either
