At some games (Heroes of the storm / Witcher 3/ sea of thieves) I have some major graphic problems. 2-3 years ago when I bought the Graphic card I played witcher 3 without any problems so this worries me. I see 2 problem reoccurring in these games.
1st problem: It often flickers. It comes from a light source always and it this is horribly annoying. in Hots smth like this happaned occensionally (Video below)
2nd problem: In witcher 3 (screenshots below) / In heroes of the storm it was far more distracting as an a slice of the object went through the whole screen. Looked like a line in the same color as the object and it was very distracting....
Games I can play normally: Ori and the blind forest, various fighting games, various other metroidvenias, League of legends , Hearthstone
What I did to solve the problem: I reinstalled drivers. I opened the pc and cleaned thoroughly. I am unfortunately not very knowledgeable how to solve this kind of problem though.
Graphic card: Radeon R9 280x
