But isn't that just for the cases when SRGB is actually used on these
formats, which appears to be quite a rare case? If that's still a
problem maybe we can advertise SRGB reads for Nvidia only?
Frankly I don't yet see any other way to fix that without some game
specific workarounds. And for that particular game only _R5G6B5 is
required, I don't have any real examples for the other formats the
patches concern.
