Testing Out Mesa's GLSL-To-TGSI Translator

The VDrift racing game also did not have any major advantage for GLSL-To-TGSI. Worth noting is that Bryan Cain has said within our forums, "I've run some tests with the nv50 driver on my NVA5 card, and like you said, there's no real difference. This is probably because unlike r600g, the nv50 driver has an optimizing shader compiler. The performance being similar is the reason that I emphasized GLSL 1.30 support instead of performance in my original message to the list - performance-wise, there are maybe a few gains to be made from GLSL->TGSI over GLSL->Mesa->TGSI, but not incredibly. I didn't think to test the CPU usage in my tests, though."

There was nothing interesting to see out of the average CPU usage.

No clear findings from the GPU usage, either.
