For xVision 1.21 and XP11 – and no other shader add-ons.
Tested using ActiveSky and ORBX TEGB (photoreal).
I generally use XP11 with VMI Twick (which allows much greater control – and in “real time”). This is my first attempt at a “native/no frills” preset – and some of the night lighting functions need further testing.
NOTE: There are substantial differences in lighting between default XP scenery and photoreal (eg. ORBX TEGB), so the preset comes in two variations:
Basically the same preset, but with tweaked brightness and saturation Photoreal->Standard
