So very recently I dipped into speedrunning the game and actually got some really good times in the underworld but I'm faced with a rather major problem as I'd like to submit theese runs to speedrun.com - the entire playthrough everything is smooth sailing but as soon as I reach Tartarus I almost always end up getting some form of stuttering (which can be seen as edits/cuts/splices, making runs invalid for any official leaderboards)

Sometimes it's the entirety of the location except for the final fight, sometimes it's just the entry room, sometimes its a singular stutter but it happens much more often than not and ONLY there.

Anyone faced theese problems? Got any clues what I might look into within SL-OBS settings to fix the issue? (also sorry if this shouldve gone in the games forum section instead, i figured its more of a recording thing)

EDIT: thankfully my runs so far got verified and accepted however question still stands as I rather not submit stuttering video in the future
