hi ive just recently built my computer a few weeks ago and for some apparent reason every game i run it dosent run smooth it would be laggy or when i move around with the mouse to look around itd be very slow. also its a pretty decent computer that was built around 1.5k gear. im very frustrated cause i asked around and i was told to just update all the drivers and gpu . and still it dosent work and im running everything under the graphics im suppose to be running, my friend has a slightly similar computer but less cause its a lil bit old and he runs everything on ultra. i am very confused did i do something wrong? here is a list of all my products in my tower
