I have seen the option under Settings- Developer options - Force GPU rendering - use 2d hardware acceleration in applications.
Should that option be checked ? What exactly does that do ? Sounds like would make phone snappier/ smoother ? But does it chew up more battery ?

I believe it works in a way that if a dev hasn't added hardware acceleration to their apps yet, it will attempt to do so.. but I could be wrong. I see no ill effects doing this either.
I enabled it, see if it helps ? So far it makes scrolling through XDA posts more fluid smooth. So must be doing something.
I am on ROM Android Revolution HD 2.1.3.

I see it in developer options but I don't know what it does
Does it make the phone faster or something?

I don't exactly know, but I always keep it unchecked because it likes to make a lot of apps look wonky or not work. I suppose we'all know soon enough, though.

It forces 2D hardware acceleration in older apps that aren't hardware accelerated. Sometimes it'll make older apps behave weird because they are not built for HW acceleration. I always leave mine checked and haven't had any real issues thus far.

Been thinking about this for a while. Exactly what type of apps benefit the most from having GPU Acceleration enabled and what type of apps have bad side-effects from having it enabled? I noticed that if you have it enabled and try to click on the weather graph in the "News&Weather" app it produces a foreclosure.

Hi,
I take you mean "force GPU acceleration"?
The setting in the dev section of the phone just forces it on, it doesn't "enable" it...
What I can think of is "old" games and graphic intense apps, not supported and developed anymore ... or very rarely apps that don't support this GPU.

You're right I did mean to put "force GPU acceleration" lol. It just seemed weird to me that it borks the weather graph in the News&Weather app and causes it to force close. I've had it enabled for a while then I disabled it didn't really see any difference in most apps[games & everyday apps] I've tried.
Double Post
Yeah I just left it off and I never had any problems ... if there EVER occurs to be any lag or something in a graphic intense app I'll turn it on.
As long as there aren't any problems, I'll just leave it off, I don't think there is much benefit, if at all, for 99,9% of the apps
Try Facebook without gpu acceleration just scroll down and look at the frame rate its just not smooth. Enable gpu acceleration swipe Facebook off from task and do the same scrolling again.
By scrolling I mean. Flick your finger and let go.... difference is massive in smoothness . If you can't see it theres clearly something wrong with your eyes

i just tried it, its horrible.
out of curiosity, leaving gpu acceleration on will impact battery life no?

Turn on {} Developer Options -> Force GPU Rendering
I'm a tinkerer and had turned that on a while back when dinking with the stock settings. I started having freezes, Home Page reloading, slow everything, HORRIBLE power useage, and I was basicly just hating my phone.
I was to the point of thinking about selling it and getting a SGS3 but I went into the settings and saw that was still on, turned it off, and haven't had any problems since.
Obviously this is one of those YMMV type options. I'd say stay away from it.

ive always left force gpu rendering on. Never had a single problem. I keep it on simply because of the transitions seem another. Weird that yours did that. In all honesty i think its pretty standard default setting to be on on asop roms

I've had apps that tell me to turn off rendering before using. The one I can think of is picsay pro. I know there was one more but I can't remember.

I've been using gpu rendering since ICS released for my former nexus s. Never ever had an issue. But the again I've been using the same palette of apps forever lol

Never noticed that message till now. Also never had problems using that app with it on. Then again all I really use that app for is to resize things and fix colors on occasion.

According to pocket now force gpu rendering is basically used to off load the graphical tasks given to the CPU in apps that aren't optimized for ICS. ICS has this option enabled by default when writing apps for it but with apps written on GB down to cupcake 1.6, gpu rendering when writing apps is off by default.
Basically, leave it on as its probably helping your CPU run older unoptimized apps more efficiently since it doesn't have to process the graphical UI for that app too.

Doesn't disabling hw overlays in development options do this or similar?

Idk if it is. I have been waiting for someone to chime in who has more knowledge than me..
Sent from my SPH-L710 using xda premium
this is not necessary. the s3 has enough cpu and gpu horsepower to handle most anything you can throw at it, unline the adreno220 of the original Evo.
As this may pertain to samsungs internel hardware, i just wanna confirm if anyone on these launchers on this phone has experinces this little jitter lag when you scroll thru homescreens..seems as if when you swipe the screen stutters and doesnt move to the next one..also when u scroll fast thru homescreens it does this..if there is a fix please direct me to it..its so annoying when i cant find anyone talking about this.. Thanks
I used my friends phone on Apex and Nova and it didnt stutter at all.... and besides, its a dual core processor Snapdragon™ just powering a launcher, i dont think lags would occur. Even if they would, i find it minimal.
EDIT: my friend's phne is the intl version with the Exynos 4412 Quad so i dont know if it applies to ya. You could try flashing MPEngine™ 12SE because the script minimized lags on my phone clocked at 184-921MhZ
Sent from my R800i using xda app-developers app
A stutter here and there isn't abnormal. If you are getting stuttering on almost every transition, that definitely isn't normal.
Assuming you are running stock, you might want to consider a custom ROM which tend to be smoother. You could also try just rooting and playing with your CPU clock settings.

Thanks guys..i been runnin custom roms and launchers since day one.dnt knw what could cause it..maybe ppl dont notice it..it isnt lag really it seems like sometimes it seems like it doesnt make a complete transition idk its weird..gs2 after ics update had the same issue
Sent from my SAMSUNG-SGH-I747 using xda premium
Try changing the animation and transition speed. Lower the number, faster it is. Also, if that doesn't work you can try disabling hw overlays. All those are under Developer Options. Here are my settings on Paranoid Android, but i use the same settings for any ROM i run (i did not disable hw overlay, but there's the option)
I think it may be with the hardware..its more of lil stutters in transition pages than lag..havent seen samsung addresss it thou :/

I'm on Apex, no issues at all. Make sure if on Apex the setting "Use Alpha Effect" is disabled in the Home screen Settings.

I've been on TSF Launcher for 5 months now. No lag whatsoever.
Expensive, but we'll worth the money IMHO.

Animation and trasnition speed are the first thing I did. haven't noticed much lag on Apex.
