5 years ago Please report the water problem to the amdgpu guys. This is very likely a driver bug, it doesn't happen on any other configuration & I don't see how anything would cause that.
Gamma is identical to QuakeSpasm with OpenGL 2 enabled. It literally uses the same gamma shaders. vkQuake is not using hardware gamma ramps, it only has the shader path.
Im running the latest master compiled on my machine. My gpu is RX580 with opensource amdgpu driver. The underwater fx is bugged when the statusbar alpha is set to 0. i uploaded an unlisted video to youtube. Also a quick report of gamma settings are interpreted to high in vkquake. quakespasm with value gamma "1" looks right. But vkquake is way too bright and washed out. I have to increase gamma to 1.5 to make it look right.
