In the case of AMD, the Gallium-based open-source OpenGL drivers also manage to compete very well with AMD's proprietary OpenGL drivers, both in terms of performance and features, despite the fact that the proprietary drivers are much more mature. See: https://www.phoronix.com/review/radeon-spvp2020-linux https://www.phoronix.com/review/radeon-spvp2020-linux There's even a working Direct3D 9 driver based on Gallium3D. With an appropriately patched WINE, you can use it to run old Windows games quite nicely even on integrated graphics or with low core count CPUs. Here's some reporting: https://www.phoronix.com/news/Gallium-Nine-Better-2021 https://www.phoronix.com/news/Gallium-Nine-Better-2021 I hope that with NVIDIA's new open-source kernel drivers, now Nouveau can push forward and get good performance like Mesa's open-source drivers for AMD. That'd be awesome, and it could pave the way for mainlining NVIDIA's new kernel driver.
