I am having an issue with my driver lately, i cant alt+tab out of a game when im playing since it does not take much for the computer to start freezing everything as if it was becoming slower and slower until it freezes completely, but the problem stops when i alt+tab back to the game. In warframe, when i alt+tab back, its perceptible that the graphics became poor when its starting to freeze but it slowly goes back to normal since i came back to the game. i had sudden freezes in other games too that made me incapable of playing. It makes me think that its a driver problem because i havent change anything in my setup and i didnt have this problem earlier.
My setup:
motherboard: asus M5A78L-M LX-BR
processor: amd Fx-8300
graphic card: amd RX 570
