hey man, thanks for the reply! unfortunately, I am already running Shadow Boost and the problem persists with/without it. I've noticed that opening up any kind of menu, like workshop, pipboy, etc. seems to bring on the "bug" or whatever it is. One of my GPU's usage goes down to 30-40%, and the game lags like crazy for a bit even after I close the menu. But the problem does happen during regular gameplay as well. I probably should have posted my load order and mods. Vogue ENB 0.13 Vivid Shadowboost MSI Afterburner OSD (toggle off and on) Mod load order : Again, this didn't happen a couple months ago and I can't for the life of me figure out whether it's a MSI problem, patch that screwed something up, a mod, etc. If anyone has anymore ideas, I would greatly appreciate it!
