Disable HW overlays + force gpu rendering
- Thread starter Underground_XI
- Start date
rendering a view goes through layers or abstractions, even passing through dedicated hardware doing the job. hardware overlay allows the renderer to take a couple of regions aside and treat them optimized. then theres the cpu and gpu. usually android decides which abstraction is best for each view, taking things like transparency into account and what not. you switch hw overlays off, project butter goes out of the window but cpu and gpu still do the job. you force gpu, the composition will be done by your gfx chip. just don't touch it - its meant for developers picking up debugging output.

I am rooted, and I'd like to know wether this does improve performance of the CPU cuz the GPU is rendering the stuff. I don't care about the battery.
Thanks in advance

You won't notice any considerable improvements. But can cause unintended side effects in apps (mainly embedded images not displaying)

dear Mr Alex you are right you may not notice any discernible difference but you free up to cpu to do more especially if you're writing intensive apps.my advice keep it on free that cpu baby
Indeed. I specifically logged in, just to be able to thank the dev. I reject the whole "take and run" thing.
Simple way is to use a working init.d script. Open it using a Text Editor and erase all lines. Copy the lines from sgatechwork to the file and save it to /system/ect/init.d. There are some Apps to emulate init.d if your ROM/Kernel does not support it.
But if you don't know how to use it, why do you want to use it? Do you know what it does?
Thanks @sgatechwork !
Odd. I don't recall ever seeing or posting in this thread, and I haven't installed the script. Seems about par for the course for me. Anyways, I read about it, and it sounds like a nifty script. Since you say script (and I would concur, based on the lack of a file ext., and the file size)... it would be placed in the init.d folder in system/etc/init.d, as long as your kernel supports init.d. If not, there are apps to run scripts w/o init.d support. The one I know of is Boot Shell [ROOT]. Also, there's an app that lets you choose which folder you wanna run your scripts from, called init.d Scripts Support. However, the most recommended init.d managing app, based off of what I've read most people recommending, is Script Manager - SManager (there's also a paid ad-free version Script Manager-SManager(NoAds)). Hopefully at least some of this is found helpful. Sorry the response is so late. :?
Thanks so much, it worked nicely on my Sony Xperia S (aka Lt26i) on stock rom, with init.d support (Universal init.d support)

Hi there. I wonder if it's possible to disable GPU rendering in lollipop. My phone is still using gpu to draw the UI even after I uncheck 'disable HW overlays' from developer options. I am having lag issues while playing games. I think it's because System UI is always using GPU and as a result my games are laggy, but those same games work perfectly fine on kitkat without any lags.
I can see GPU usage curve spiking from 40% to 80% all the time in system monitor.

Don't touch force gpu rendering. But disable hw overlays reduces lags in system animations when u browse your phone. I use this cause I hate animations lag. But note that when enabled it'll cause little lag in gaming.. so it's your choice.
