Video freeze after 2:25 for 3-5 seconds

It always happens to me when bombs explode for the first time in a mission. It should depend on the video card memory, mine is just 1 GB.

Thanks for the reply...
This delay is not caused by explosions or other special effects. Rather, it is always at the 2 minute 25 second point after the mission flying begins.
I have just tweaked my processer to 4.2 GHz which vastly improved smoothness and general game-play, but the action still stops for 3-5 seconds every time after taking control of the plane.
I have not noticed this delay in "Campaign" mode and have not watched for it when flying multiplayer online. I'll check it out today...
