Viewport Ghosting and Flickering in 5.4.1/5.4.2 Possibly Rect Lights

(post deleted by author)

For anyone having this kind of issue, your GPU is probably overheating and thermal throttling. It was wasn’t noticeable at all regarding frame rates on my side, but thats what was causing these ghosting glitches, I opened and cleaned my pc pretty hard until I couldn’t see any dust, the GPU isn’t throttling anymore and the issue is gone, this isn’t related to any game ready/studio driver versions or w/e bs.

I’ve tried that, but it did not help. Only switching to the older game ready drivers helped.

Turning off ray traced shadows on overlapping lights also helps if you absolutely need to be on the latest drivers.

It is absolutely related to drivers and lights that cast ray traced shadows. Maybe you have overheating issues, but that is not the root cause of the problem.

There are no overheating issues to speak of, and your explanation does not account for it suddenly becoming better when you downgrade your drivers or turn off ray traced shadows on overlapping light sources.

Then we’re all on different situations I guess, the only “fix” quoted above that worked for me was the console command, but that isn’t a fix as it just totally wrecks the shadow quality. I’ve tried the oldest driver version available on both Studio Drivers & Game Ready using DDU, that didn’t fix the issue at all. I clealy had overheating issues as I don’t clean my pc often enough, and this is the only action that I took that provided a real fix, I’m not having the ghosting issue anymore at all, even with the latest Studio drivers and regardless of how many light sources I throw in there.

its not a hardware issue i have this problem too on my rtx 4090
