Those who play Wolfenstein II will be happy to hear it no longer crashes when using the RADV drivers. There's also a DirectX to Vulkan fix for Intel gen7 iGPUs and some fixes for the Freedreno driver for Qualcomm's Adreno graphics hardware.

The Mesa 19.1.x back-port copr for Fedora does not yet have this technology but it will likely be the quickest way to get access to this given that Fedora 30 is still using Mesa 19.0.x.
