In first person, it's a jerky motion as my character tries to holster weapons while a few under water colored bars flash on the screen like I’m getting ready to go under water. If I try to move forward, it is an extremely slow jerky hoping motion. Switching to third person, shows my character having what looks like an epileptic seizure, and I still get the flashing color bars. Sometimes, if I try to walk forward, the character will go into a swimming motion in mid air. It will also cause me to fall through thin, wood plank bridges.
I first noticed it while I was in the lowest level of Shroud Hearth Borrow. Now I'm in Fallowstone Cave and the game is unplayable. I can hardly move, and I'm unable to use any weapons or spells. The seizure like motion keeps me from doing anything productive.
I’ve tried multiple things, from reseting all graphics to basic settings and removing all tweaks (including resetting ini's), to removing all mods (which are only texture related, so I didn’t think they would be affecting this); but nothing is helping. I haven't tried reinstalling, but I did verify the steam cache.
I thought I'd try some beta graphics drivers next, but I really don't think that's going to help.
If I come across something that works I’ll post it here.
