You're 100% right, it's pinpoint accurate. My fault. When I first played it almost 2 years ago for a youtuber event I must have missed something since I set up my game in such a rush.
As for the BFG Edition, I see now thanks! Kinda neat the sens in DOOM (1993) and DOOM II is pinpoint accurate too, something the newer official ports can't say lol. Only problem is, I think they struggle with higher polling rates.
