First, game runs rather slow, 30 FPS average, usually lower.
Now, after playing for a few days, no matter what I do, FPS stays at 60... DA FPS HAZ FIKSED ITSELV!!!
In fact, just for laughs and wanting to see this game cry for his momma, I decided to record a video of it! No lag. No lag at all for over an hour of recording.
Yez but munky lag is online nut single plyr! Yez, I no, no s-s-s-s-s-s-stuttering or s...l...o...w framerate @ all.
No, I didn't secretly update my DirectX, drivers, or anything else. MY BOY, WE'VE GOT OURSELVES A GENUINE MISTER Y!That is, the bugs are still there (random crashing) but it's not as bad as it was before.

I had heard somewhere that leaving Vsync ON during that mission might also have allowed you to progress, which it did for me. Yay!
Hope that might help those of you that still have the issue.
