[Bug 42592] The Witcher 3 has poor performance ( buffer access flags are ignored)

--- Comment #74 from tt_1  ---
Anyone out there has a Polaris 11 based Card and got it working in playable
frames per seconds? Using amdgpu from kernel-4.14.21, mesa-17.3.5,
libdrm-2.4.89, and it is somewhat 1-2 fps with an rx 550 and wine-3.2 - this
plus the buffer patch gives me sort of deadlocks, black screen which can't be
killed with keyboard.
