Ubuntu 18.10 Is A Nice Upgrade For Radeon Gamers, Especially For Steam VR

With Dota 2 on OpenGL at 4K with the RX 580 and RX Vega 64, the performance was flat across the tested configurations... Dota 2 isn't the most demanding game and is rather CPU bound even with the AMD Ryzen 7.

Dota 2 with Vulkan also didn't see any real changes with the Ubuntu Cosmic Cuttlefish upgrade and overall the RADV Vulkan performance is a few frames slower than the RadeonSI OpenGL results.

When running Dawn of War 3, there is a performance boost for the Radeon RX 580 (Polaris) in upgrading to Ubuntu 18.10. Troubling though is both graphics cards regressed when moving to the latest Git stack.

With the F1 2017 Vulkan-powered racing game, the RX Vega 64 also regressed when using the very latest Git stack but at least the performance is stable on Ubuntu 18.10 compared to 18.04.
