Was watching this run and noticed he paused his split but so did what appears to be his igt

IGT stops for cutscenes, radio calls, pausing the game, and during loads. The autosplitter in its current form displays that same time. So, yes his timer is pausing, but that’s because anyone with the autosplitter setup and is comparing game time will see the timer pause a lot in this game. That’s the same as someone who isn’t using livesplit to keep track, it’s just how the game works.

Yeah im just using the SRT and keeping a mental track for now

Yeah, the autosplitter feeds in the actual game time. So when you see Livesplit's timer pause, that's because the actual game time is pausing too. This happens during cutscenes, pausing the game, and radio sequences.
