I get this with some FPS games on PC, seems ok on PS4 though. Seems a bit better these days since I got a 144hz screen, as for Fallout 4 I have it increased fov and also set the frame limit to 70fps I think it is as it was running too fast. I also tend to limit my game time but as previously mentioned playing frequently I think you may get used to it so maybe build up over time, tend not to have too longer sessions though and I turn off if I feel I'm going sideways. Hope that helps.
