This has been happening for awhile and I've not been able to find any help, but whenever c4d runs an auto-save, or when I undo for the first time after a period of time, c4d lags hard and/or freezes for 15-30 seconds, and it will also run a refresh of every single material I have loaded in to my material manager. It's beyond frustrating, especially when it's occuring every ten minutes when auto-save is set to run.

I've tried going back to older versions of C4d, I've tried deleting preferences, reinstalling display drivers... I don't know what else to do.

If anyone can provide assistance, I would be greatly appreciative if I could get this resolved.
