Linux Gaming Performance With Radeon Vulkan NGG Culling

For the Radeon RX 6700 XT and RX 6800 XT graphics cards there tended to be small but consistently higher frame-rates when NGG culling was enabled. For the Radeon RX 5600 XT there was virtually no difference with RADV's Timur acknowledging a very small impact on Navi 1x.

All of these small performance optimizations have added up quite well for the Mesa RADV driver over time.

In some games there was no measurable difference but at least we haven't seen any glaring regressions with the Radeon RX 6000 series.
