If anyone wants to help test:
SpecialK64.7z (7.6 MB)
This version adds a Paper White Luminance slider (default = 250 nits) to control the mid-tone luminance level. Setting this lower is important in some games (i.e. NieR: Automata) that do not handle gamma correctly in their original SDR form (lol).
This should become the official release of 0.11.1 as soon as I re-write this calibration guide. Make sure to reset HDR preset values, especially paper white.
