si_edgey So dependent on the hardware.. 4475 doesn't exist for the broadwell generation, but 4474 on the 20.* branch does. It sucks. I didn't try force-installing the 21.* version, though I probably could. 5166 is latest, but it's just a lame security update and meh. On the HD 6000, the Windows catalog wants to serve up 4531 which is ok, and as an optional, 4624 which I find to be the best one I have seen to date on a HD 6000 in W10. It's disappointing that there never will be driver updates for this GPU other than in the Linux world (slowly).
KM I believe the findings. I often use the 4624 driver in YCbCr mode, and it does not use dithering in that mode but RGB does.
