[Q] Will Accelerated 2D drawing improve app GUI/UI? - Android Q&A, Help & Troubleshooting

Can somebody explain to me how the new Accelerated 2D drawing implemented into ICS is going to improve the quality of apps? will it improve the GUI/UI? If so how?
I know the basics about it, i just want to know the extend to which is can be used. Will better graphics and animations be possible?

Bump bump bump

It will make scrolling and animations look smoother and lagfree iirc

[Q] GPU rendering/Rosie Scroll

The major thing I look at with roms is the smoothness of the rosie scroll. A lot of roms are perfect but I can't stand the laggy/slow scrolling. I noticed that even if there's a smooth/ultra smooth rosie option on some of these roms, it is still slow, but on other roms like Prime XL, it's smooth as butter ( I don't use prime because of all the random reboots). Is this because some ROMs don't have GPU rendering? If that's the case, how would I go about enabling it or forcing it?
Find a Rom that has it check the build.prop copy it (it should be labeled) past it into your build.prop if you can't do it I can do it for ya
Sent from my mom's Nexus S 4G..... It's True lol
Nevermind, I found the build.prop. debug.sf.hw = 1 enables GPU rendering right? Is that it?
I'd be willing to bet that a tweak such as forced gpu rendering would maybe make the scrolling smoother, but I can't imagine it being more stable or safe than without.

[Q] Implement CRT off screen animation without turning off GPU GUI acceleration

Hi, I have a P500 and have successfully applied the mod for the CRT off screen animation. But what bothers me is that in order for the mod to work, one must disable GPU GUI acceleration by adding a '#' to the beginning of the line in build.prop containing debug.sf.hw=1, making it a comment. Is there anyway to implement this mod without disabling GPU acceleration?
no replies huh. ugh.

stock settings Developer options. Transition&Window Animation

has anyone ever bothered to go into developer options in settings and turn off transition animations scale or windows animation? to see if things are speeded up even more so. I noticed with windows animation off, the setting screens just pop onto the screen vs. a more gradual appearance of it. I'm trying it with those off to see if any noticeable increase in UI speed. although my UI was fast n lag free before, I'm just curious to see if speed increased even more. Someone brought up a point before that one reason IOS UI is fast because they don't have fancy transition animations n such like android. so cutting those off "should" theoretically improve ICS UI.
I just use the app "spare parts" to speed up the window and transition animations.

I have that app also. but instead of just speeding them up, you can completely shut them off. things do move alot faster as far as ui goes. if you put the transitions to 10x you get this cool slow mo fading effect when switching to certain tasks or apps. but going into developer options and cutting off windows animation and transition animation does speed things up. they pop on the screen that much faster.
I might try out the spare parts thing to see how that fares. reminds me of an app I had on Ipad, jailbreak needed, that was like a fake gpu accelerator. all it did was speed up window animation and transition animation. it worked well so ill take a look at this. I'd still think completely shutting them off is the fastest method vs. speeding them up.
edit update: I just tried out spare parts like you said. Do you know what speeding up the windows n transitions animations really does in that app? lol all it does is change the developer animation settings. I compared it. OK for example stock developer settings has windows and transition set at 1X by default. now if you go into spare parts app and put those animations to fast, all it did was change developer options animations to .5x speed. so really that spare parts app is not even needed for that. you can go straight into developer options and change this without needing that app. I did it a few times and looked back n forth at spare parts settings then developer options and all it does is change developer option speed. which I can do within Asus settings itself. even in the app description it says cutting them off brings fastest device performance.
I still wish we could find out a more technical answer on if Forcing GPU rendering helps or not. and if it does, is there extra battery drain? only seen mixed answers. nothing concrete yet. I have noticed in the developers section there's a custom rom calles WSG rom. one of his features is that he basically cut off CPU rendering and forced GPU rendering full-time. been hearing good things about how fast it is. I wonder if its the same as going into developer options and forcing gpu rendering. Anyone has any technical insight into this?
I think I was the one who mentioned the screen transition in a thread where someone was calling the TFP laggy.
I have mine set to none. I don't see why anybody would use screen transitions. Isn't instant screen changes what everyone wants?

cutting off those animations does bring instant screen changes. I think I will leave them off. UI is even faster than before with them off. everything, as far as UI. launching apps, etc..is instant.
here is technical info on what happens when you Force GPU rendering. I asked the developer MasterZen about it in his thread. He isbthe Creator of WSG Rom, where he added the feature of removing software(CPU) rendering and forcing GPU rendering full-time. here's his quote:
" FULL GPU rendering puts our tablets into a state where all the rendering steps, both rasterization and scene composition, are handled by the GPU. The rasterization step in the rendering phase takes all the display list objects, either vectors and bitmaps, and creates textures to be rendered. Then the textures are copied on to the buffer. Thus freeing up our CPU for more excessive task"

Is this how iOS does it? Are there any drawbacks to full GPU rendering, more crashes..ect?

That's how apple does it! I am telling you guys why do you think they use extensive amounts of VRAM and also why they leave their CPU clocked so god damn low!
We should start forcing that in all roms and send a letter to Andy Rubin if we find it helps a bunch!

I'm not noticing any drawbacks at the moment on full gpu rendering. MasterZen said in his thread that he will put together a beta team to see if it has any drawbacks or improvements to battery performance.

good idea. plus people should definitely go into developer options and cut off the windows and transition animations, tablet is Wahhabi more snappier now. add force gpu rendering and UI n everything becomes really fast. mines was already great before but cutting off those animations took it to another level. I'm forcing gpu rendering also to see how that fares also. we might be on to something
Wow... i just changed the Windows and transition animation setting to 0.5 instead of 1.0 and enabled the force gpu option. There is a Noticeable improvement in GUI speed for the interface. I like the eye candy so didn't want to completely turn them off.
Thanks for the tip!
Def a speed boost when turning off animations.

OK. ill do it tonight. I doubt the animations would affect anything but forcing GPU rendering could have dramatic effect for the positive in the benchmarks. as far as gpu side of things goes.

what is HWcomposer

hey guys
can i know what is HWcomposer actually? what work it does? i know it doesnt work in JB but dont know what it does actually . what features i may miss without it?

HWcomposer enables UserInterface (UI) rendering via GPU
u can see the link below to understand more about the same

hi there! I have been wondering what this means too.
What are the effects of having HWcomposer not working? Laggy graphics?
Force GPU rendering isn't enabled by default, so how will this impact performance? Battery life?
Thanks!
According to the HW composer link HW composer is there since Honeycomb so how is it a JB enhancement all of a sudden?
So, SurfaceFlinger in Android is what actually puts together the different screens and surfaces, using OpenGL (the GPU).
Hardware Composer (HWC) is a little module that plugs into SurfaceFlinger, and helps offload some of the surface compositing onto specialized display hardware. Usually this is just a 2D GPU, but sometimes graphics parts have special "overlay" planes that can be used, instead. This lightens the GPU load in several ways, potentially improving performance.
It's been present since Honeycomb, but the API is updated once in a while to support more features. The [Android Sync infrastructure] was added in JB MR1, and requires a whole bunch of new APIs to be implemented for this explicit synchronization. It also relies on some Linux kernel APIs which are only present in v3.4+.

{ICS}{Misc} -> Force GPU Rendering

Hi all, I would like to have opinion from you guys.
Under Development Settings, There Is a Force GPU rendering option
Force GPU Rendering []
Use 2D hardware acceleration in applications
Is it good to enable it or not ?
Some of my friends say Yes, some say No.
Well, I would like to have opinion from you guys now

Graphics are handled in one of two ways, "software", which means the primary CPU does the heavy lifting, and "hardware" which means the GPU does the lifting. Hardware rendering is better because it frees up CPU clock cycles for other stuff, so the phone moves faster/smoother (plus GPUs are designed to excel at the types of calculations graphic intensive applications do). This feature supposedly forces programs to use the GPU to paint 2D objects on the screen (2D was previously unsupported, so most apps and the base UI were software accelerated, 3D should be hardware by default), but it can cause crashing, bugginess.
Devs have the option to enable hardware acceleration with a simple line of code (according to Google at least.) If they choose to enable it, the app will be hardware accelerated regardless of what you set in there.

Thanks for your info, mate
So that's why some app behaves weirdly, right?
My camera behaves weirdly. And the black background of apps tends to have a white gradient from bottom up.
so, you enable it or not?
Your Sound Mod rocks too, waiting for Clear Audio+

No mate I dont have those problems
Yeah i enabled it
Are you using Chainfire3D?
You can try to compare and contrast with GPU rendering on and off.
Eg the back ground of root explorer. There will be LIGHT WHITE GRADIENT from bottom up.
No, I'm not using ChainFire3D. But I've tried it before. It ruins my graphics, games don't function properly even.

YOU HAVE TO INSTALL PLUGINS FOR THAT
You can run tegra games on ray
Yeah, I know. But it still don't function properly. Sheesh...
I only use it while I'm gb where everything works fine.
Mate, spare our poor Qualcomm S2...
Playin Tegra games on ray it's like pushing it to the limit ouch
If it's Qualcomm S4 with Dual Core 1.5GHz Krait Processor. You're good to go
