Where to begin battling horrific overuse of CPU

[Keltyrr]

Sunday campaign is sure a slow game. Using in the ballpark of 60% CPU, 3.5gb ram, but GPU is only operating at 10-15%. Setting vsync4 does not help in the slightest.

Here is it.

Player here: Lag takes the form of 5+ seconds of FGU simply being frozen and unresponsive, and when it freezes is erratic. Sometimes it occurs quickly after the last freeze, sometimes it freezes after 10-15 seconds. Most inputs are dropped during the freeze and the textbox cursor often resets to the beginning after the freeze ends, causing mixed up messages. Between these freezes, the game runs as smoothly as I'd expect. So there are brief moments of fluid gameplay. All players experience the lag/macrostuttering, even on powerful computers, and this problem started somewhat recently possibly around the time we moved to a new map. Fantasy Grounds freezes indefinitely upon trying to close it, requiring a forced close.

The log files show hundreds of errors being caused by an out of date extension (or probably more than one). Try disabling extensions or testing in a new campaign without them or make sure that the extensions you are using are still valid or are up to date.

@Keltyrr - please ZIP up your campaign and post it here so we can review to see what might be causing the issue. Details on how to ZIP your campaign can be found in the FG Wiki here: https://fantasygroundsunity.atlassian.net/wiki/spaces/FGCP/pages/1725825027/How+to+ZIP+Your+Campaign+for+Support+Developers

If the ZIP file is too large to attach to a forum post, please upload to a cloud storage solution and share a link to the file here.

Alright, may have found the suspect. I still had the bmos version of Advanced Effects.

Tested with just one player at this point, but lag seems to be effectively none now. Real test would be this sunday when next session is, but so far looks promising.

I've been getting similar issues to this as well. Through troubleshooting I had isolated it to what seems like some sort of incompatibility with FGU 4.6+ with my audio interface (A focusright scarlett 18i20.) What CPU are you using and what is your audio setup?
