29-Way GPU Comparison On Linux From Kepler & Cypress To Today's Pascal & Vega

Metro Last Light Redux requires at least OpenGL 4.1, so it can't run on all GPUs supported by the R600 Gallium3D driver until if/when the "soft FP64" support lands for allowing OpenGL 4.x for the entire Radeon HD 5000/6000 series. Metro Last Light Redux at 1080p can get by with around a 60 FPS average on the GTX 750 and HD 6950, but the performance with newer GPUs has come a long way.

A fun look at how fast Portal runs at 1080p with current graphics cards and Linux drivers... It is interesting to note in this heavily CPU limited game, the RadeonSI Gallium3D driver stack was outperforming the NVIDIA OpenGL Linux driver.

Or even at 2560 x 1440, Portal runs fine on all of the graphics cards tested. Though it was too fast with the GTX 1080 Ti that there seemed to be an odd race condition hitting with the driver and the speed of the game that it would crash, though the GTX 1080 was working.
