Are you "shelling out" to Windows? ie: With the game running, use Alt-Tab or Windows-D or anything to go to the desktop or another app? Do you have much running in the background of the computer (systray) while playing the game? Had you emptied the Save folder prior to using FotRSU? I had four computers (a moment of silence for the recently departed one) running FotRSU, and none had issue as you describe. I don't know about others' experiences, of course. My weakest machine was a Core Duo quad 2.1gHz, 8 gig of ram, 2x 2gig 7200rpm HD, with an nVidia 560Ti. The recently departed was a Core i5 5th gen with 8 gig of ram, a 1TB 5400 HD and onboard Intel HD Graphics, nothing spectacular as far as hardware... ??
