Jesus christ, It's like 30 different issues.

Yeah, Double Agent got the worst PC port of the series. Great game but this port can be infuriating at times.
Sucks because the game itself isn't even that bad. It's still pretty Chaos Theory-like, maybe with more action. Well, at least it's finishable with the patches, fixes, and if you're careful with the bugs.
