GLAMOR 0.5 Acceleration Library Released
Phoronix: GLAMOR 0.5 Acceleration Library Released
Intel's GLAMOR 2D acceleration library over OpenGL is further glamorized by its new v0.5.0 release...
Time for some new benchmarks? ;-)
I might actually be home this weekend, so maybe I'll try to do some comparisons on my 6850 (EXA vs GLAMOR 0.4 vs 0.5).
Great, please report your findings.

SNA is a highly hardware specific optimized solution, currently tied closely into Intel chips. It has heuristics in it that try to determine whether an op should be passed into the GPU 3D hardware, 2D hardware, or performed on the CPU. That can vary between GPUs.
SNA was started a while ago to try and wring out any extra performance possible from Intel chips. Glamor started later on, as people thought that SNA was too complicated and should be dropped, but it seems that SNA has caught on with some people and proven itself good enough that Intel will likely go that direction. But it's essentially a fair amount of work that will have to be done every time they bring out a new GPU generation, while Glamor would basically just work without much effort.
