Hi, I recently bought a used 1080ti, evga sc black. Ive had it for about 2-3weeks now. No problems everything checks out.
3dmark firestrike score is 17370 (23209 graphics, 12674 physics)
but ive noticed a drop in fps in the games im currently playing (Overwatch, cod4)
I am getting 70-90 frames on both games. I have both games on max settings but i am sure that i was getting at least 120~ fps on both games with the same settings. (1080p btw)

The only thing that ive done was update windows? ver 1803 (I think ive had 1803 for a while now though its prob just utilities that was downloaded the other day)
and game update

all drivers are updated. 3d mark score is still the same. no issues honestly aside from the sudden dip in fps in both games.

I just want to make sure that its not my gpu/computer having problems.
