Over the past couple of months the top runners of the game have decided that to make competition, especially for world records fair, we need to introduce an fps cap at 120 fps. Its a fact that higher fps increases the speed with which the AutoHotkey skips through cutscenes and slower PC's with older equipment are at a big disadvantage. (An example of how big the difference can be, 120 vs 200fps loses up to 20s in the first 12 minutes of Old Patch). So, to meet a compromise between fast dialogues and hardware, and also to make the dialogues consistent for everyone, we decided to introduce an fps cap at 120. This will apply to all runs in the Main Categories if you use the AHK(All Records except NG+ are already played with the cap), and it needs to be shown on screen.

Tl;dr:

Capping your fps at 120 is now required due to hardware differences and to create an equal playing field in general.
