Hello! I had replaced some old things in my old computer with some new budget products from Newegg. I predicted FSX to be at full power with the new things I purchased (with the exception of a video card) but my performance was still pretty laggy with fsx.cfg tweaks and some setting tweaks applied. And since I heard FSX ran mostly on CPU power and not much on GPU, I really didn't consider a new card until now. I was wondering what the problem could be and would I need a new video card? (specs below) Thanks!
