--- Comment #1 from Roland Scheidegger <srol...@vmware.com> --- My guess would be the test is invalid. The "mrd" meaning is very precise both in d3d10 and OpenGl, and we were being sloppy there before - it really should be exactly one bit (for unorm depth formats). I quickly looked at the test and I don't quite understand what it does to find the ideal mrd. I suspect the math doesn't work out somewhere because the float math is right at the limits of depth buffer precision (24 bit in this case). Do closed source drivers actually pass this (and if so I wonder what their calculated ideal/actual mrd values are)? -- You are receiving this mail because: You are the assignee for the bug.
