Hmm...very interesting. Since 1.22b I've been getting random freezes and crashes, usually when switching areas (so it happens a lot in town). The game will either lock up completely for 20-30 seconds (sometimes crashing), or it won't load the new map, so I'll hit an invisible wall for 20-30 seconds (sometimes crashing).

On my old laptop, which is using Mobility Radeon HD 3650 graphics, I have no problems. This led me to believe it's a thing with the latest Nvidia drivers on my desktop and their new Adaptive AA and FXAA things.

But I do have an old Nyko AIRFLO comtroller plugged in...I'ma try unplugging that tonight and see what happens.
