    Phoronix: ATI R300 Gallium3D Driver Seeing A Big Performance Fix After Being Regressed For Years

    For those still running decade and a half old ATI Radeon graphics hardware like the Radeon Xpress 200M found in numerous notebooks back in the day, a performance regression in the R300 Gallium3D driver is being sorted out after concerned users on this vintage hardware began bisecting and testing patches for a regression to this old ATI open-source driver that appears to have been adversely affected back in 2017...

    In the end R300 will get a fix and possibly an perf optimization enabling the disk shader cache? So you can teach and old dog new tricks after all

        a little while ago I tried blender 2.8 on a radeon hd 2000, I don't remember if it is based on this driver, it worked, visually, but it had problems with the selection of the objects .. I hope they solved even with these small defects

          Nope, that uses the r600g, not the r300g driver.

            Just recently I put x300 on a "power supply test rig" , just to check if power supply works. I booted recent ubuntu and I was shocked that desktop is totally snappy and scrolling 9gag on firefox was without lag. I did not test any games though.

              What I really want fixed is the ability to use KMS on the old PowerPC CRT macs. My eMac has a Radeon 9600 and when KMS loads the screen goes black. Only way around is to use older software with UMS support, or nomodeset and fbdev.

                We'll be waiting for extensive benchmarks with PTS.

                  Good news.
                  Improving the drivers also for older hardware makes Linux a real all-rounder.
