NVIDIA vs. AMD Linux GPU Performance For THRONES OF BRITANNIA
If wanting to run A Total War Saga: THRONES OF BRITANNIA with extreme settings at 1080p, the GeForce GTX 1080 Ti is pretty much needed.
At 1440p with high quality settings, the Radeon RX 580 was coming in at just above 60 FPS and running in line with the GeForce GTX 1060. The RX Vega 64 was in line with the GTX 1070.
For ultra quality settings at 1440p, a GeForce GTX 1080 or better is pretty much needed for this Vulkan-powered Linux game.
