    Phoronix: Performance Work Coming Up For Mesa 7.11

    While Mesa 7.10 was just released, there's already been some work beginning to land in the mainline Mesa code-base for the ATI Radeon Gallium3D drivers to improve the performance...

    r300g seems rather stable in most situations, so any performance gains are welcomed.

      Yeah, I wonder how well r300g/c compare to Catalyst 9.3. I know we've had that r600g comparision recently, but the r300 drivers seem much more mature and prolly have seen more optimization as well.

        Yeah, if only r300g was any usable on my laptop with an Xpress 200m, instead of displaying fuzzy random horizontal lines...

          The last comparison i saw had it between 50-60%. With the recent optimizations Marek has committed I'd guess we might be over 60% now. It would be an interesting test for Michael to run again. Especially if he could do it on a couple machines - one with a really fast CPU and another with something much slower, to see if the driver is CPU limited.

            Don't forget that r300g covers a very broad hardware spectrum

            r300g covers old R300 chips all the way up to more recent R535+. And it must be difficult to get meaningful comparisons anyway, when Catalyst 9.3 is only compatible with horribly outdated X servers.

            Personally, I'm much more impressed with the functionality and stability of r300g than I ever was with the Catalyst drivers, even if r300g's 3D performance has not yet been optimised.

              I think a comparison would still be useful. Even if other components have helped to speed-up r300g we'd still be able to confirm that there is room for improvement.

                There is always room for improvements. ATI were developing their proprietary driver with a huge budget for 8 years I think? We can't surely compete with that, we can only get closer to its speed...

                I think Dave Airlie compared performance between r300g and fglrx some time ago and the numbers weren't very good. I can only say that there has been some new optimizations added recently, so it's now probably better than it was.

                  Well you guys tried really hard and did a wonderful job. It's just too late. The military beat up people, sociopath lie constantly model doesn't work at these population levels. They'll kill a bunch of people this year and those people will simply drop out of the collective conciousness by not returning to source. Kind of like the 60's drop out but with teeth.
                  Linux will likely get swallowed by apple in a couple years who will use python to spy on everybody.

                    Give us some of that stuff you're smoking, dude.
