Radeon Vulkan Variable Rate Shading Benchmarks For Boosting RDNA2 Performance
F1 2017 is a native Linux Vulkan-powered game port by Feral Interactive. This game was also seeing some nice gains out of the VRS 2x2 override.
HITMAN 2 via Steam Play was seeing just some minor changes in performance with VRS 2x2 enabled.
Shadow of the Tomb Raider, which is native to Linux and Vulkan, was seeing some decent speed-ups from enabling VRS 2x2 without much quality loss.
