So, im playing overwatch, i just recently upgraded my i5 6600k to an i7 8700k and i use an gtx 1080 and 8gb of ram, i have a custom water loop so the temps are low, i play the game with a 300 fps cap and when im in the practise range for example i get 300 fps but in more demanding maps i stay at 220 fps even though the gpu is only being used 50% and the cpu is also only being used 60% and only 4gb of the ram is used, i cant think of any way why my fps shouldn't go higher
