GRID Autosport was out in 2014 as a racing game powered by the EGO 3.0 engine. This was another game port carried out by Feral Interactive and was released for Linux in December 2015. GRID Autosport on Windows uses Direct3D while under Linux is obviously using OpenGL.
With minimum image quality settings, the game was able to deliver playable frame-rates at 1080p on both operating systems with the GTX 1060 and GTX 1080. However, the Linux performance was much slower. With the low quality settings, GRID Autosport on the GTX 1060 was about 70% the speed of the Windows build when using Ubuntu with the newest NVIDIA driver. The GeForce GTX 1080 was also around 70%.
When increasing the game quality settings to ultra at 4K, the GTX 1060 was above 60 FPS on Windows but dropped to 45 under Linux with the GTX 1060. The GTX 1060 on Linux was 65% the speed of the Windows GTX 1060 performance while the GTX 1080 was also at 65% the frame-rate.
