DCC with mimaps had been disabled in the RADV driver for the latest-generation AMD Radeon graphics hardware. This was done some time ago but the underlying issues have since been resolved for about a half-year. With no problems occurring anymore for games like Hogwarts Legacy, Hi-Fi Rush, and Sonic Frontiers, Mesa 23.3 is going ahead to re-enable delta color compression with mipmaps for GFX11.
No performance numbers were provided as part of the merge request , besides Pitoiset ending the MR with, " More DCC perf! "
Mesa 23.3 is shaping up to be another great quarterly update to the open-source OpenGL and Vulkan drivers and should debut as stable around the end of November.
