I don't have any of the problems you listed. But, I loose my custom keyboard key binding assignments in the canned cut-scenes when you have to interact (e.g., jump from the helo, or duck behind the fallen tree) and have to use the default key bindings to get through the scenes and back to regular game play and the bindings then revert to my custom assignments. That's really bad! Also, the AI is really, really stupid. Not a finished product.
All that said, I can play the game without constant crashes. I've got that going for me, at least
