Most of the time, the game play is very reactive and smooth, but once in a while, mouse input is interrupted so I can't turn or look up or down with the mouse. Keyboard input is sometimes completely interrupted, but will sometimes work. Total time for interruption is about 5 seconds at max. If I haven't been blown away, play usually resumes smoothly as if nothing happened.
The event sometimes seems to be linked to crossing or paralleling an edge, though not always. It's not related to CPU overload as I can usually move normally in crowded rooms and bot activity proceeds normally while I'm frozen. (Bots, explosions, missiles, keyboard moves)
