More optimizations on the way for Dawn of War III in Mesa

By - | Views: 5,053
A Mesa developer has put out a set of 42 patches to help improve Dawn of War III performance on Linux using Mesa. It focuses on the use of KHR_no_error to save some more CPU time.

The patches landed earlier today in Mesa-dev, so they are not yet accepted into Mesa-git. You can find the start of them here. Below is what Mesa developer Samuel said:
QuoteThis series adds KHR_no_error support to various GL calls, mostly
the ones used by the DOW3 benchmark. Piglit* updates are coming shortly.

I didn't do any benchmarks, but this should save few CPU time here and there.

*Piglit is a set of automated testing tools for OpenGL

The KHR_no_error extension, from my understanding, removes certain error checking to allow for more performance.

Fantastic to see performance continue to be worked on! Article taken from
