RADV Vulkan Gaming Getting Closer To RadeonSI OpenGL Performance

Dota 2 at 1080p is now performing closer with RADV to the RadeonSI performance level than in the past. But RadeonSI is still leading to faster results. RADV's slower performance is also due in part to some game engines not having their Vulkan renderers as tuned as their mature OpenGL support.

Dota 2 at 4K saw significant benefits from the delta color correction code that landed a few days ago, but still not enough to push it over the edge. Especially with RX Vega GPUs their Vulkan driver support is much less mature.

Dawn of War 3 is still significantly slower with RADV than RadeonSI for AMD Linux gaming.
