Many fans have speculated that Fallout 4 on PC will run at 30fps just like it’s console counterparts after an article popped up on Digital Spy claiming this to be the case. While 1080p at 30fps is confirmed on both Xbox One and PS4, it is however not the case with PC. Bethesda addressed these reports via Twitter saying..
“Fallout 4 is 1080p & 30fps on Xbox One and PS4. Resolution and FPS are not limited in any way on the PC.”
