im literally losing my mind here mid-match my screen suddenly filled with flickering triangles. it looked like this:

this happens only in one specific game. the card is a used RTX 3080. my heart dropped cuz I know artifacts can mean dying VRAM. I dont have money for a new card right now. is there any hope?
i already tried a fresh driver install and a different game. the artifacts show up there too after a while. im hopnig someone can tell me teh right order of tests.
