Testing 60+ Intel/AMD/NVIDIA GPUs On Linux With Open-Source Drivers

GeForce GT 520 - The GT 520 Fermi graphics card would hang while loading Unvanquished.

GeForce GTX 550 Ti - This mid-range Fermi graphics card would hang while loading Reaction, Unvanquished would fail with Nouveau DRM errors about failing to idle the channel, there were similar problems with Warsow and Xonotic too.

GeForce GT 610 - This low-end graphics card was extremely slow and the monitor would stop displaying after a while.

GeForce GTX 750 / GTX 750 Ti - Nouveau's Maxwell GPU support is still in its early stages. The GTX 750 Maxwell series still requires the proprietary driver's microcode for this latest-generation GPU and its Gallium3D support is in early stages. The Nouveau Maxwell support will hopefully be better by the end of summer and into a usable state on par with Kepler.

GeForce GTX 780 Ti - I was running into mode-setting issues with the Linux 3.15 kernel, but after a few attempts, I got it to light up but it was running with only the LLVMpipe driver and not the NVC0 Gallium3D driver.

GeForce GTX TITAN - Bad rendering with Unigine tests and Unvanquished.

Those are the main issues encountered with the different NVIDIA GeForce graphics cards tested using the latest Nouveau stack supplied by the Linux 3.15 kernel and Mesa 10.3-devel Git. Now onto the open-source AMD problems...
