Linux Gaming Performance With Radeon Vulkan NGG Culling

The newest performance optimization merged this week for Mesa's "RADV" Radeon Vulkan open-source driver is NGG culling for Navi 1x/2x graphics cards. NGG Culling "NGGC" isn't enabled by default at this time but can be easily activated and depending upon the software under test can provide some minor performance gains on top of all the other optimizations seen in recent times for RADV.
