The fps cap that the game uses is determined by the your monitor refresh rate (typically 60Hz or 120Hz), and dividing it by the 'iPresentInterval' value. In general, you are advised to keep the game's default settings and continue to play the game with a 60fps cap. These types of issues can also occur if the game/launcher incorrectly detects monitors that are set to refresh rates above 120Hz as being set to 120Hz.
These issues can be caused by your video card outputting an excess of 60 frames per second, having mods, or your computer's video card drivers being out of date which can result in the game moving too fast or too slow.
