The INI edits are already in place, so that's not it. I've even tried setting the Affinity to two cores with no luck. Everything in my Steam folder and below is listed as an exception in my A/V. I'm using the fnv4gb patch, specifically the one for NVSE. I've not heard of the fake fullscreen trick, got any details or a link? I've tried selectively disabling mods to try and locate the culprit, but I've been unable to determine which mod does it. I'll go back and try again. The freezes are just so random that it takes a long time to realize whether or not it's fixed. I've tried to remove all the mods in an effort to load them up a few at a time but the saves won't load. I'll see about dismissing all companions and waiting 72 hours in a small world cell and trying again. I was wondering about the Canteen and Timescale mods. I'll try removing them as well. Should I be bulding bashed/merged patches for each test or just leave them off until I find the culprit? Thanks for the reply! Cheers! Skunky
