NVIDIA GeForce GTX 1660 Ti Linux Gaming Benchmarks
The GTX 1660 Ti still kept up with more than 60 FPS for Dawn of War III on Linux rendered using Vulkan when running at 1440p with ultra quality settings. The RX 590 fell just below the 60 FPS average threshold.
With the Mad Max game on Vulkan, the GTX 1660 Ti was competing with the RX Vega 56 when running on RADV.
Rise of the Tomb Raider, the latest Tomb Raider game available for Linux and rendered with Vulkan, was a bit much on the GTX 1660 Ti when at 1440p with very high quality settings but for what it's worth the performance was still around that of the RX Vega 56.
