20-Way NVIDIA/AMD Vulkan Linux Gaming Performance Comparison

With Thrones of Britannia at 1080p and ultra quality settings, the Vega + RADV performance is very competitive against NVIDIA with the GTX 1080 and RX Vega 64 even competing... But as mentioned at the beginning of this article, this is one of the games where NVIDIA is currently investigating, so the NVIDIA performance may be more competitive once getting to the bottom of that situation.

The situation at 4K with low quality settings is similar...

Long story short, if looking for the very best Linux gaming performance, it's no competition that the NVIDIA GeForce GTX 1080 Ti by far is the best -- assuming you have no issues with their closed-source driver approach. With these tests of NVIDIA 396.45 vs. RADV Mesa 18.2-dev, the RX Vega 56/64 were still generally performing in line with the GeForce GTX 1070 except for a few rare cases like Thrones of Britannia that are being investigated. The RX 580 Polaris graphics card with its quite mature AMDGPU+RADV open-source driver support was meanwhile very competitive against the GeForce GTX 1060 on this latest driver stack.
