'Android 4.3 and Nexus 4 are white on June 10' - tweakers.net

One of the improvements that will be in 4.3 graphics performance. There had Romain Guy and Chet Haase yesterday a session, which they did these improvements explained

Halfway through the session I had unfortunately to a meeting so I did not catch the whole story, but the improvements include at least.:

(1) Display List re-ordering. That is, graphic operations are performed in a different order on the GPU apps then they perform. For example, for example (and if possible) first signed all nine patches, then all bitmaps, and then all text. This does need to change, which is an expensive operation, the GPU is much less and therefore gives a performance gain.

(2) Display List merging. Now the graphics operations are grouped by type, different operations can be merged. As can be instead of one-by-one, which is a drastic reduction of OpenGL calls has caused. Several lines of text at once, for example, signed Who has experience with GPUs will know that it is much faster to make signs than to implement. 100 calls 100 things in a single call In the demo with the Google+ app, this was reduced by half the number of GPU calls.

(3) Multithreaded rendering. The actual GL calls are still running on the main thread, but some calls also require some software-based calculations – they are now multithreaded run

These improvements are all the way. ‘free’ and sit in Android itself, an app have nothing to do. Hopefully nothing breaks the src=”http://tweakimg.net/g/s/wink.gif” The exact performance gain will be is also the question, but it looks very promising.
