[SOLVED] Good enough specs but bad performance?

Admittedly this is my first ever self made rig so I might have overlooked something obvious idk.

I got an RTX 2080, i5-9400f, 600 Watt PSU and 1x8gb of ram but I can barely play COD Warzone on the lowest possible graphics. Shouldn’t I get more performance out of this?
