So hey guys...
I bought my pc 5 months ago back then i could play RL on 150 fps Rainbow 80 gta 80 smite 150 ...
And these days i can play gta on 70-50 rainbow on 60 (these are ven on lower settings when i bought i played on high and medium and for gta it's the same but for rainbow it is high and low) RL i get like 130-110 and smite like 130-70 and i think it's pretty weird i went down like 30 fps or like 10-20
Give me some advice plz :D
