After a driver update, two updates ago, for my nVidia RTX 2800 certain textures started shimmering/blinking. I first noticed it in De Other Side dungeon, where the big troll was blinking from dark blue to even darker blue.
Doing a bit of research, I found some posts from several months ago that said MSAA was the culprit, but I had MSAA off. So I turned it on, and the blinking stopped. But when I went into The Maw I saw large, white, horizontal flashing bars, and turning MSAA off eliminated them, however later other textures were flickering. Now certain textures flicker whether MSAA is on or off, and toggling it temporarily fixes the problem. It would be nice to find a permanent solution, as it is quite distracting and annoying.
Any help would be greatly appreciated.
