I recently upgraded to a rx 5700xt and ryzen 7 3700x but I realized that the gpu runs nowhere near 100% in most games, LOL runs at around 30% which im fine with because i still get 200fps but i played Arma 3 today and the gpu barely went above 50%, I was getting frame drops and terrible fps. How can I make it run at full utilization?
