NVIDIA GeForce GTX 1660 Ti Linux Gaming Benchmarks
A Total War Saga: Thrones of Britannia was running well on the GTX 1660 Ti at 1440p with high quality settings where this EVGA graphics card was about tied with the RX Vega 56.
Warhammer II, another Vulkan-powered Linux game port, put the GTX 1660 Ti up around the RX Vega 56.
When running the Unigine OpenGL benchmarks on these cards for fun, the Radeon cards on the RadeonSI Gallium3D driver continue to perform extremely well and beat out the NVIDIA competition. Too bad though the Unigine engine is mostly used by industrial/simulation applications these days and not any popular games.
