RADV+ACO Outperforming AMDVLK, AMDGPU-PRO Vulkan Drivers For X-Plane 11.50 Flight Simulator

At 4K and even with very high visual settings, the NVIDIA performance still appeared to be CPU bound for X-Plane 11.50 with Vulkan. But worth noting and the focus of this comparison was the RADV+ACO Vulkan driver continuing to deliver higher frame-rates than the official AMDVLK and AMDGPU-PRO driver options. But the results against NVIDIA show that even RADV+ACO still has more room to improve in delivering higher performance.

But exciting for the Radeon Vulkan performance is even at 4K having lower peak frame times on Radeon than the NVIDIA GeForce cards tested on their proprietary Vulkan driver.

Across these resolution/quality tests and others, RADV+ACO on Mesa 20.1-devel was showing measurably better performance than the AMDVLK and AMDGPU-PRO options. This largely jives with what we have been seeing in other Vulkan-powered Linux gaming tests with RADV being quite good across Polaris/Vega/Navi with only a few exceptions and when enabling the ACO compiler back-end pushes its capabilities even further.
