Hey!
For about six months now, since I upgraded to a GTX 1080 & i7 8700k, my fps has been considerably lower than it should be. For example, when playing black ops 4 max settings, I should be averaging 130-180fps, However, I am averaging 60-110 fps. Another example is CSGO, where in all maps I am getting 200-300 lower fps than I should be.
My GPU runs at about 70-75C when playing.
My CPU runs at about 40-50C when playing.
I have reset my PC multiple times but ultimately end up with the same issue. Any thoughts?
Thanks.
