    Phoronix: A Look At The Huge Performance Boosts With Nouveau Mesa 17.0-devel On Maxwell

    Landing this week in Mesa 17.0-devel Git was OpenGL 4.3 for NVC0 Maxwell and a big performance boost as well for these GeForce GTX 750 / 900 series NVIDIA "Maxwell" graphics processors. Here are some before/after benchmarks of the performance improvements, which the patch cited as "1.5~3.5x better", when testing a GeForce GTX 750 Ti and GTX 980.

    I was wondering if it is possible to edit the actual BIOS on the card to have higher frequency on boot.

      As much as I despise nvidia, it's good to see its open source drivers make progress.

        Back in the day, yes, but these days I don't think so. Not sure nibitor or whatever that third party Nvidia bios editor is even maintained anymore.

          for the first time nouveau on gtx 750 / ti can be considered for gaming

            Yeah, you can do it. Use nvagetbios, nvbios and an hex editor to edit the bios in the way you want. Then you can ask nouveau to use a certain bios file instead of reading it from the GPU. This way, no risks outside of the thermal/power ones.

            All the nouveau-related tools are in envytools, found on github. Have fun!

              Unless you have a pascal card then it's perfectly possible to use nvflash (cracked linux version exists) and MaxwellBiostweaker(wine+dotnet30 required), for Kepler cards use KeplerBiosTweaker.

                That doesn't do anything to the boot process. It just adjusts parameters that the driver reads out from the various tables that say what frequencies to use for when it decides to change clocks. To adjust the boot clocks, you have to change the boot scripts.

                  I'm so glad I bought a GTX 970 last year. Seems like Linux will always make things run like its 1995

                    Is it really too much to ask to add a bar of the performance with the closed driver? Nice to see there is an relative improvement but it totally unclear what the absolute performance of this driver is.
