        What do you think, smartass? Benchmarks with this patch. RadeonSI development is highly sought out by us gaming enthusiasts.

          You want a benchmark that says 0 (because it segfaults without transform feedback support) and some random number that shows it now works?

          Or did you somehow get the idea that this feature would improve performance of some game?

            Yesterday I did some tests with phoronix-test-suite applying the transform feedback patch from the mea-dev mailing list: 121 fps in Xonotic 1080p High quality and 102 fps in OpenArena 0.8.8 1080p. Card is an AMD Radeon HD 7950 with linux 3.12 (drm-next merged on top of linux-3.11).
            ## VGA ##
            AMD: X1950XTX, HD3870, HD5870
            Intel: GMA45, HD3000 (Core i5 2500K)

              Good to see this enabled... This gets us one more step closer to GL 3.1 for SI, and that would have us caught up to R600 (roughly).
