I have recently upgraded my GPU from the RX 590 to the RX 5700 and for some reason, i haven't gained any frames, Gmod only runs at 110 frames at the most, when with the RX 590 it went up to 200-300, GTA V runs at 30-45 FPS unless its set to low and then it hits 55-60 frames if im lucky, hitman 2 runs at 25-30 on both high and low settings. i am also running with 16 GB of RAM and my games are running off of an SSD not that that makes much of a difference in FPS. Portal 2 runs at 70 FPS with my RX 590 and 50 FPS with my RX 5700. I've closed most of my background apps that used it to the point i have 3-4 % background use and when gaming my CPU is only hitting 60-70 % usage in most games and my RX 5700 is running at 40-50%. neither the CPU or the RX5700 is overclocked, but my RX 590 was overclocked an extra 175 MHz. any ideas why?
