I know in the end I need a new PC, but I am holding off for as long as I can. I am running Tower 3D pro and using voice. I run dual monitors and like to put the ADIRS window to the second screen. When I do that my frame rates drop dramatically. I have turned all video settings down to the minimums and it doesn't help. My video card is a NVIDIA GeForce GT 710. PC has 12GB of ram. CPU is a an AMD A10-7800 Radon R7. Any help would be great, thanks in advance. Larry Johnson
