Its now been more than a year and half since Ice Cream sandwich was released. While many apps now use gpu rendering, the older ones that don't get a huge smoothness increase when this setting is enabled. I have been using this setting since I got my galaxy nexus over a year ago and the difference between on and off is huge. Its even worse on devices like the nexus 10 where without the setting on many apps are almost unusable but become butter smooth with it on. I think it is time for google to enable this setting by default, especially now that they hid the developer settings menu away.
Does it increase battery usage?
No they shouldn't. If an app benefits from GPU rendering then that's up to the app developer to implement. Forcing it causes problems with some apps.
Is op to lazy to turn it on every time he/she flash a ROM ? Lol

No, I always have it on. But most people don't even know to turn it on (people that aren't into tech) and it makes a huge difference when its on. Also I have yet to see any apps that have issues with it on and it doesn't increase battery life. In fact it improves it in many cases. Go use a nexus 10 and open adobe reader without the setting on. Then use it again with it on. The difference is huge. It goes from like 5 fps to nearly 60fps. Many app developers are still targetting gingerbread which means that gpu rendering is off on those apps. On these 720p and 1080p phones it makes scrolling very laggy when performed in software.
Yeah, viewing pdf files without gpu rendering on is pure nightmare. Just like scrolling in xda app. The difference is huge.

Yeah, the benefits far outweigh any cons and for every one app it breaks (i haven't found any in over a year) there is 1000 that it improves greatly.
I forgot about this option thanks for reminding me
How beneficial is the force 4x MSAA do you think?

This is a developer setting and apps who are intended to be accelerated, already are. There are too many fags playing with those options and then ranting on the Play Store about app behavior. Dev settings were hidden with a reason with 4.2.2. Jesus, there just isn't a month where this **** isn't brought up again.

Name me an app that doesn't work with it turned on. I haven't seen any.
The issue is that there is no way to turn on acceleration by default in an app unless you target honeycomb or higher which means you'll have to make a seperate gingerbread app. The pros of making this on by default far outweigh the cons and any apps that don't work with it will finally be pushed to update to use it.

Well then google should make it an opt out setting for app developers and not an opt in. I still haven't seen any other apps with the issue. This is how it is when targeting ice cream sandwich but for gingerbread theres no way to enable it.
Even if that one app has issues, thousands of other apps get huge performance increases and no issues. I'd say the benefits are still worth the drawbacks.

Do many people use this option or is it just more trouble than its worth? Are their any real benifits?
Sent from my Galaxy Nexus using xda premium
Very little benefit for much trouble.
I don't, I find it makes many apps more laggy. So I just leave it off.
The CPU is good enough to handle the rendering by itself.
it depends on whats running, as it makes some old apps run much better. however going and ticking and unticking the box all the time is a pain, so i just leave it off
leave it off bacuse many apps don't work well with this feature enabled
If the app supports this, you will find that it runs more smoother.
But it runs good on the MIUI, but I didn't try on CM9.
On or Off is depends on you, but if you just use GN to call and SMS, you don't need this

One would hope that the app would be compiled with GPU support so that it wouldn't have to be checked ever.
I have a couple of questions regarding some options under "Developer Options" in the settings menu. The first questions I have is regarding GPU Rendering. Should we enable it and has anyone noticed any positive/negative effects after enabling it? The next question I have is about the option to limit background processes. I have been limiting the processes to 4 but it seems like every time I go back into this sub menu. it is always back to it's stock setting of "Standard Limit'. Does anyone know how to make it stay on 4?
Force gpu rendering in theory makes ui more responsive and fluid, but if apps are not specifically coded for that, they can look weird with black bars and abnormal colors. I noticed this in few apps and turned it off. I am not sure why ur background process number is not sticking, but honestly u will be more happy if u leave it at default coz with 2 gb ram there is enough memory to run all ur background services and some more.

Dude my background processes keep reverting back to i noticed when i went back in i know it stuck for me on complete stock but i am on free gs3 rom right now and think it might be something conflicting with the modified build.prop tweaks he may have in there. ??? Anyways that switched to limiting 4 background processes and putting window animation and transition animation to 0.5 i noticed a difference . Although i dont really think our phones need this because of the 2gb of ram now maybe the g2x did and as far as gpu rendering u will only notice a difference in some apps that are optimized for this. If not u will notice some artifacts on the screen thats usually your first hint to switch it off because it isnt playing nicely with that particular App. But yes especially in some games u should notice a slight difference. Again if it was the g2x having no hardware accelaration then having it u saw a big difference....our gs3's our such beasts that its minimal to our eyes

All hi tech games like asphalt,spiderman, avatar. cs portable, gta3 all play great. Videos do too. You can also add debug.composition.type=gpu to build prop and delete any other composition type that's in build prop to force gpu rendering for graphics

Thank you. Every one thinks it will break things. It is like saying I have a Land Rover with 4v4. Now, you're going up a hill and to run it up, you buy newer and better wheels. It still gets up, but slower. It would be a lot smarter to enable 4v4 so it can climb faster and more efficient. So GPU is supposed to run the Graphics Interface. Not the Processing Unit. Does it make sense? Of course not. Using GPU for its dedicated reason it is a way more reasonable thought. So why would you want it disabled?

Because you're probably not using any old apps that haven't been updated for ICS. Not jumping on the OP I'm simply stating this mod isn't needed because the GPU is already rendering everything. CPU will only render old apps so if you don't have any old apps then this mod is essentially useless. You're not forcing the GPU to do something it isn't already doing.

OK.. then riddle me this.. Using the option in development settings breaks my XDA and my FRF app, meaning they wont load pictures in the app.. However this mod has not caused this side effect..
RushAOZ said:
This mod isn't needed. The whole reason GPU rendering exists in ICS/JB is for apps that were written on GB. GB written apps didn't support GPU acceleration by default. With ICS and JB apps are written with GPU rendering on by default.
Basically these settings ONLY effect old apps that haven't been updated to ICS/GB. This is why disabling CPU rendering will break some apps as experienced by some of you above. GPU rendering is supposed.to force the GPU to render old apps and while it works most of the time there are apps that you can't force and you get errors and artifacts. So many misconceptions with this setting lol. Just leave it on. Problem solved.

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.

Its also pretty hilarious that you say this and are bending it to make your self correct..
YES newer applications that are based on the newer SDK have the ability to do this Nativity regardless of what you have checked or unchecked..
BUT it is not ONLY going to be beneficial for apps that are not.. it will force ALL rendering through your GPU and leaving the computation to the CPU giving your system an edge.. while be it a small one, but never the less an edge as far as CPU processing times and Graphics quality output ..

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.

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"

Lag...
I have read a lot on the lag seen in Android as compared to something like iOS specifically. There is lag and there will always be more lag seen in Android as apposed to iOS, due to how the OS was designed, and priorities of certain system functions. iOS gives full priority over any other process to the GUI functionality, which gives iOS a major smooth GUI (so what right??). Android gives priority to other processes, and the GUI falls near the end, I don't think it even gives a priority other than the standard Linux process priority, so the GUI appears to have lag at times, especially if something else has priority over the GUI.
Personally, I feel it was done this way for many reasons, to include helping with battery life on a Linux based system. On my Note 2, I feel there is lag where there should not be, but it does not bother me like it may others. If you have a iPhagot standing next to you, they will always point it out. We are running quad core processors that should not have lag as the power is there, however, because of the priority of the GUI being lower than many other Android system services, we see it here and there.
As far as this program... I believe it is doing some CPU governor tweaking, possibly even freezing programs on sleep. I have seen some programs that trim what the vm's can use for memory as well, so I wonder if this could be part of it. Could simply be disabling certain GUI functions which allows the GUI to appear faster. There are tricks in this forum that show you how to disable some lockscreen functions which allows wake time to be almost zero, but I like the lockscreen functions, so I can deal with the sub second lag... who cares really you know?

while the gui priority lag theory is true, this is not what lag free is doing..
If you download the app you see that it works with fstrim. Some sort of memory trimming utility that helps the os make faster decisions cause it trims the fat.
im not sure all the technical details but when you download it it gives you a brief description.

I think any lag that anyone experiences is mostly caused by tw launcher. I use nova and have all settings set to faster than light. I have zero lag. I can max out my cpu and force lag but for the most part it is non existent.
