What is this "rolling" I keep hearing people refer to? I notice that people move faster than I do in this game but I haven't seen why

Hey SuperBlitzCraig,

BFG Edition of Doom3 on steam is faster than the original version (referred to as vanilla version) of Doom3 from 2004. We are using a source port for BFG Edition Doom3 (RBDoom) which you can find a setup for in the guide section.

I'm not exactly sure what "rolling" is though. What's the context of that?

Greetings qd
