AMDVLK vs. Mesa RADV Radeon Vulkan Driver Performance On Linux
With the demanding GravityMark benchmark, both the Radeon RX 7900 XT and RX 7900 XTX were performing measurably faster on the Mesa RADV driver than AMD's own official AMDVLK driver. GravityMark was a clear-cut win for RADV.
Running Counter-Strike: Global Offensive with the Vulkan rendering option yielded similar performance between RADV and AMDVLK.
Cyberpunk 2077
Wioth Cyberpunk 2077 the results were a bit odd for the RX 7900 XT but nevertheless a clear win for RADV. What was odd was the AMDVLK vs. RADV difference with the RX 7900 XT... AMDVLK with the RX 7900 XT was much slower than with RADV and in comparison to the RX 7900 XTX results. It's like the AMDVLK driver on the RX 7900 XT had a missing optimization or incorrect handling in this case.
In any event, RADV continued leading the driver race for Cyberpunk 2077 on Linux thanks to Valve's Steam Play.
