Hi all,
I've just finished and pushed YaGL optimizations work. Here's a short overview
of what we have.
Generally, we have performance increase up to 50%. Here're some comparisons:
before | after
ChameleonMan 280fps | 420fps
Water 220fps | 330fps
GLBenchmark 141fps | 186fps
GPU top now shows 95% (previously ~60%) usage for pure X.Org and ~85%
(previously ~50%) for Tizen FS when running the demos.
TLS usage has been replaced with simple global variables.
There're also many other changes that are described in commit messages, the
changes improve code quality as well as prepare ground
for GLESv3 implementation which I'm starting right now.
P.S: The changes were verified using all our usual tests, including khronos
conformance, GL benchmarks, WebGL, etc. Tested
on linux and windows, 32-bit/64-bit, nVidia/intel GPUs. I didn't test on mac, I
guess once we have FS for emulator on tizen.org we'll
be able to test...
