PhantomX2000

hi first time im posting something in this forum bur... im realitively new to FSX and obviously new to the whole tweaking. I have tweaked my cfg many times now and with addon scenery like kai tak ( Fly Tampa) im getting 9-12 fps with PMDG 77W. If my cfg or anything you need to help me get 20 fps or more in FSX, this will mean alot to me. Also I have heard p3d is harder on graphics card so should i invest in p3d with my pc setup or can i get what i want to get in fsx with your help
