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
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.
I've seen a tweak included in some ICS rom's that state they have Enabled Hardware acceleration, which is something I think was there by default in gingerbread.
Can someone tell me how I can apply this single tweak to my rom myself? I don't like the other changes custom roms include would just like this tweak done to mine.
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
HW Composer
and can we dual boot jb and ics? is it possible?

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+.

Hi all.
I was wondering,what "homemade" tweaks like init.d/script manager scripts or build.prop do you use with your S3...
When i say homemade i mean tweaks you apply on your own,not any tweaks that come with the rom you use.
Tweaks that you've tried and liked,tweaks that you'd recommend.
Here's the things i do to make my S3 more lag free:
-Use Greenify
-Custom script for script manager attached below(updated 27/3/13)
-Build.prop almost clean as i found many of the tweaks unusable in 4.1 or to interfere with the System.
-No init.d tweaks currently (sometimes zipaling and sqlite defrag)
-Custom STweaks settings(Perseus) including overclock,they're too many to write if you want i can attach some screenies.
-Currently testing Crossbreeder mod but with the above my S3 was already fast enough so not much differency,if any.
-zRam 650mb script for a kernel that supports zRam attached below also to be used for script manager.

This one is for the soft keys, tablet-like home, menu, back buttons on screen (with respective screen reduction). Adding the line on build.prop:
Enable
qemu.hw.mainkeys=0
Disable
qemu.hw.mainkeys=1
Popular tweak, for the sake of those who don't know them yet.

So that's my list right now.
Got anything good to share?

Thank's,i read many guys use this one.
Bump?
No one uses his own tweaks,only what comes with the rom?

well, yes But i'm interested in the script you posted. What exactly did you change the minfree values and ratios to ? Would these values give more multi-tasking or are they engineered towards having free ram ?
Also Greenifying google maps (as a user app) gives a huge boost to battery life, unless you have Google Now enabled

Hehe..
Well this is leaning towards better multitasking and most importantly lag free system and multitasking.
I lowered the adj values a bit because stock S3 were killing my apps a bit too fast for me,they're "inspired" from the original Galaxy S only a bit modified to suit the S3.
I found them to be working nicely for me,give them a go if like and post here or pm me.
Except from the adj values i modified a bit the values of sysctl.conf like dirty ratio vfs cache pressure and some nr_request config.
I changed my values a bit right now and also disabled iostats to make it even more less laggy so i'll upload this when i get home.
I usually have around 70mb free ram but my S3 doesn't lag at all,yay!
Now trying 500mb zRam and it's going very nice...i may add it to the op soon...
