"Fallout 4 has been widely lauded in the gaming press as a stunning achievement, but performance issues and stuttering have negatively affected the title on all three platforms. The situation was particularly bad on the Xbox One, but the PS4 still struggled to maintain smooth frame rates as well.
On the PC, the situation was even more erratic. The Nvidia GTX 980 Ti I’ve used to test the title was more than capable of maintaining 100 FPS, the maximum refresh rate you can use to play the game without running into problems related to physics and engine issues. But there were many areas of the game where performance cratered to 25-30 FPS.
