So this kind of came out of nowhere. at first I thought it was a problem with a specific asset, but getting it everywhere on all installed UE engines (latest UE 4.18 & 19) and even old files.
Not sure what happened but just looking across a room I can see the lines and edges of some far walls vibrating, and sort of “flashing” like its z-fighting, so it throws off the lighting. It’s worse with reflective surfaces - for example, it seems to affect the lines between tiles, rather than the tiles themselves. It doesn’t seem to affect the lines directly in front of me, but a few steps ahead (in FPS view for example)
Setting temporal AA samples to 0 seems to stop the shimmering/z-fighting when I’m just standing there, but the flashing remains/gets worse when moving.
Any ideas? I know it’s not the assets as they are fine in previous videos I made. Some UE config change? I did reinstall my gfx card drivers recently, but I went back to an older version and the problem remained. Not having any problems elsewhere, so not sure what’s up.
