Mmmm, seems like the issue remains there with the .88 too after I rolled back, or at least, something stayed behind, even though I did a full DDU Uninstall, I also Uninstalled the 23/07/2025 Microsoft update that "coincidently" launched with the nGreedia driver on the same day, no change (KB5062660)
Anyways, nothing seems to take away the issue now, I can fairly replicate it easily, especially near the Board Room / Central Executive Control Point (Seen in my screenshots), you have to stand in the "Fog/Smoke" and pan the camera, some weird frame drops/stuttering, colour issues. Of course, the game uses PhysX, so, I wonder if RT doesn't play well with the PhysX smoke effect? Anyways
I don't know anymore, I give up, too much crap, and reporting on the nGreedia forums is a joke.
*Edit*
I think, I will wait for the Windows 11 25H2 to be released in October, I will do a clean Windows Install and see if things change for the better, but I sure as hell won't do that now and do it again in 2 months or so. lol
