Zink OpenGL-On-Vulkan Benchmarks Are Very Competitive To Radeon OpenGL Driver
When running Dawn of War III as one of the more demanding Linux-native games with an OpenGL renderer, at 1080p with ultra quality settings the native RadeonSI driver was just 14% faster than the Zink+RADV OpenGL-on-Vulkan combination. But even with a 150 FPS average, the Zink implementation still was very playable at 1080p.
But when increasing the resolution, Zink's spread against RadeonSI widened to at 4K being 68 FPS with Zink to 102 FPS with RadeonSI. However, this wasn't the case for all games.
With the ET: Legacy game continuing to let Wolfenstein: Enemy Territory live on as open-source, Zink and RadeonSI were running at around the same speed.
Or with Half-Life 2: Episode Two, it was the opposite of DoW3: at 4K, Zink was providing faster performance than the RadeonSI driver.
Or with Half-Life 2 Lost Coast, the RadeonSI driver maintained a lead over Zink but still both drivers led to results in hundreds of FPS.
