If it is ROTTR or Windows fault I can't say for sure but so far ROTTR is the only DirectX 12 game I've had this issue with. As such I suspect this is a DirectX 12 related bug introduced or perhaps exposed by a Windows 10 Update after July 2019 which is the last time I played ROTTR and it did not have this issue then. In the end switching to DirectX 11 was the only thing that seemed to fix it on my end.

I also tried lowering everything and increasing everything, cleaning up shaders, reverting to the same video drivers I had the last time I played, older builds of ROTTR and more. I monitored my video card temps and it never went beyond 55C. It tends to be things like smoke, mist, water, hair, fur, webs while the rest of things like rocks, trees, dirt, walls, etc are all normal. So the beauty, realism of the game and immersion are ruined by lack. The AA modes that you offered are all ineffective in removing temporal aliasing. HBAO+ is per pixel, but it's screenspace so it can't catch ambient occlusion on objects that the camera can't see and it tends to be view dependent. Now I am seeing the same thing for some parts of the screen while the camera is turned in certain directions. Hello Nixxes, You made the game extremely demanding, apparently, for the sake of beautiful and realistic graphics, but at the same time you didn’t implement a proper AA mode such as TAA - the only method that completely eliminates any aliasing. VXAO is a bit more blurry by its nature because it's sampled in larger sizes. When I played before I didn't have this issue.
