So I've found my way around a few other glitches, turning the PhysX off and what-not, but I cannot figure this one out. Right at the beginning of Chapter 3, either after the first big jump, or after climbing up the small pipes shortly after, my movement speed will go to a crawl. I walk ridiculously slow, can't do slide/jump moves of any kind, and even looking around is a lot slower too. Obviously I cannot get anywhere when this is happening, so I'm pretty much stuck.

Anybody have some ideas that might prevent this? Thanks in advance...
