I recently got my 4070 and it didn’t have that kind of issue at the start. Trying to find a solution to this for a while now and couldn’t find anything that would help. I had an RTX 3060ti and an RX580 as well before this, and the artefact problem was still present on my PC then. I don’t think that might be a GPU issue… Cause I am not using GPU light mass… Am not sure
