I've been playing over 200 hours with multiple mods with no major issues up until now. After updating one of my mods (Project Commonwealth) I can't seem to move 2 feet without my character stopping dead in his tracks and have a seizure for a few seconds before he can move another 2 feet and have the same thing happen. I Returned the mod to it's previous version, same problem. I uninstall it completed, it's still an issue. I even disabled ALL of my mods and started a new game just to test if it was even a mod problem and I was having a seizure all the way over to the wee baby Shawn. I've used the resetini command and tried running it in borderless mode and I'm still having seizures all over the place! My fps is stable and all the npcs are moving around just fine, and like I said before everything was peachy-keen yesterday. Anyone have any ideas?

Edit: Well I solved the issue, I tried playing some Binding of Issac and found the same issue with movement. Turns out it was my keyboard wigging out on me. Unplugged/replugged it and everythings fine now. Mods, please feel free to close or delete this topic

Might be worth leaving open just to demonstrate that terrible performance is not always Bethesda's fault - unless they snuck in your house and damaged your keyboard. Glad you got it sorted.
