Win 10 Insider Preview build 16291 is now released to Insiders on the Fast Ring. Microsoft blog gives details here: https://blogs.windows.com/windowsexperience/2017/09/19/announcing-windows-10-insider-preview-build-16291-pc/#iRQVlOVWTsescv4b.97
I just changed my Windows color setting.
Usually I have it set to RGB.
Now I changed it to NVidia Color Settings YCbCr422 in Windows, then chose HDTV (rec.709) in the game and the colors are now fine for Fullscreen.
The colors are bad when YCbCr444 (rather than YCbCr422) is set in Windows and HDTV (rec.709) in game.
In the past I was able to choose RGB in Windows and HDTV (rec.709) in game.
I have to use Limited Output Color Range though. Not Full like usual, because it's not a choice for me when I'm set to YCbCr422.
But I guess I have to set Windows to do NVidia Color Settings YCbCr422 (not YCbCr444) with Limited Output Color Range if I want to play CoD BO3 in Fullscreen, but not necessary for me to do that if playing Windowed (Fullscreen).
Something is majorly different for Black Ops 3 with this driver.
The colors are weird when I'm set to Fullscreen, and the fonts are fuzzy.
My mouse cursor is not visible either.
As soon as I change to Windowed (Fullscreen), colors, fonts, and mouse cursor are showing correctly.
Black Ops 3 having trouble with WDDM 2.3 I think.
Somebody (ARandomDolphin) in the NVidia forums said: "Tom Clancy's The Division has this issue too! Switching to windowed (fullscreen) in The Division fixed the color distortion issue. Battlefield 4 is not affected by the color problem even when running in fullscreen mode."
Call of Duty Infinite Warfare does not have this color issue when running fullscreen with this driver.
