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.
So as we all know, that the iPhone Browser Safari offers a way smoother pinch to zoom and scrolling experience than the Android Browser (Especially on singlecore phones). So I head the only reason why the iPhone Browser is smoother is because it just takes a thumbnail instead of live rendering, so you actually only navigate on a thumbnail of the site untill you stop touching the screen.
I was just wondering if it's possible to change the Android Browser so it does the same thing, giving us a smoother experience?
Why hasn't anyone already done it?
Bump I guess
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.
Hi,
There seems to be some issues with animations (Both CSS and JS/jQuery, for the techies).
I can see it clearly with mobile menus animating in Chrome (and web view apps). The animation is really laggy compared to my 2 year old Galaxy S3, which is quite smooth.
It doesn't make sense
I've tried enabling forced GPU acceleration in the developer options, but no change.
Anyone else having this issue with the Z2 ?
It's the same with the Z2 Tablet for me.

What do you think about Scrolling on Android?
I copy and paste that interesting post from here:
https://www.reddit.com/r/Android/co..._source=amp&utm_medium=&utm_content=post_body
My question Is: It's possible, to tweak scrolling values? When yes, how could you modify it on Android?
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Original Post:
...I am generally very happy with Android's scrolling. I like medium to fast scrolling on Android more than iOS (iOS limits the speed to let things load and keep things smooth), it feels more responsive and when you flick it, you get the speed you expect.
But when it comes to slow scrolling (this is when you're focused and are looking for something) iOS has a small tweak that makes it very satisfying to scroll. And this tweak is with the inertia. On iOS, when you make a small flick, the screen keeps scrolling, it creates a feeling of whatever you're scrolling is "on ice" or like a cube of butter on a smooth hot pan, it keeps moving. This produces a very nice effect. On Android on the other hand, when you make a small flick, the screen stops immediately like there is too much friction underneath. It does not feel as "airy" and "slippery".
I've made a comparison video to highlight the difference:

It would be awesome if Google tweaked slow scrolling to be more like iOS and left fast scrolling as it is. I think it would create a better experience.
