Phoronix: Much Faster MSAA Anti-Aliasing Is Coming For R600g/RadeonSI

Marek Olšák posted a patch today to significantly boost the performance for games using multi-sample anti-aliasing (MSAA) on both the R600g and RadeonSI Gallium3D drivers...

excellent news. This change concerns also with rv670 amd gpus? thanks

One of the most needed improvements, nice work.

Nice. Does this require kernel 4.6/4.7?

This looks pretty nice, can't wait to see comparisons once this hits git. After offchip tessellation, another nice performance step. Also yesterday there seems to have landed a commit promising some enhancements e.g. for The Talos Principle: https://cgit.freedesktop.org/mesa/me...d61252e1cffb98

I'm loving all these performance improvements coming through, I can't wait to test them. I would be surprised if by next year mesa isn't leading on the majority of games benchmarks.

Good one, Talos is one of those games that run much slower on Radeon than on old fglrx. I wonder if this patch would improve other games with the same problem, e.g. Witcher.

From https://lists.freedesktop.org/archiv...ne/119461.html :

Please ignore this patch. It doesn't work.

One of the patches was ditched(?)

I know with Shadow Warrior, enabling Anisotropic textures drops the games speed significantly. As in, same settings, 720p+anisotropic ~= 1080p-anisotropic in performance...
Changing from FGLRX to RadeonSI, I was quite surprised at the performance loss.
