Thanks for the reply. I disabled PhysX on my GPU but it had no effect. After turning it back on, I went into the game and tweeked some settings.
I turned off HDR and removed the frame rate cap (I moved the slider to 0). That appears to have fixed the problem with sticking on terrain, although I only had time to play for about 20 minutes after the tweek.
I'll play around a little more to see if I can isolate exactly what setting was causing the problem and then try the support tool to send you a report.
Thanks again.
