RADV+Zink vs. RadeonSI OpenGL Performance On Mesa 23.2-devel

Xonotic was running well on Zink relative to RadeonSI with these RDNA3 GPUs but still there is room for squeezing more performance out of this Mesa code.

It looks like Mike Blumenkrantz has some work to do with tuning Zink for glmark2.

Here's where the geometric mean stands at the moment for Zink on these Radeon RX 7000 series graphics cards while using the RADV Vulkan driver. But no doubt this positioning is likely to improve once Blumenkrantz reads this article. Overall Zink continues to show that it's increasingly capable of serving as an alternative to hardware-specific OpenGL drivers.
