Hello Dear Pc Master Race ,
Here is the problem , I have Gygabite Rx 6600 Eagle , Paired with r5 5600x , 16 ram , Gta 5 was freezing when loading city or something , 0.1% fps dropped to 0 , And Then I played fortnite was freezing in lobby , spawn map , landing and after that It was having good fps , When I turn on dx 12 It showes this type of "artifacts" , Also in shadow of tomb rider It showed some kind of lindes on npc and lora , and on boxes and everything . I reinstalled drivers Installed first ones , then I updated again and It helped with only tomb rider artifacts. Can this be that my NEW Gpu is dying or needs to be replaced or Its broken ? , Temperatures are good , 3D Mark Timespy 7500 without overcloking , when overclocked 8300.
(on last video black lines are from monitor and bad phone camera , the bugs are on the top of laras head )
