I'd like to know this too. I run the game from Steam, with an NVIDIA GTX 460 graphics card.
I have not had any problems before, but I recently bought a new monitor and increased the resolution to 1920x1080. Now I have the same dots and strange graphics inside the cockpit as ripmax has. Everything else looks fine.
EDIT:
I found this thread:
http://forum.1cpublishing.eu/showthread.php?t=27437, and can confirm that the problem goes away if I turn off the epilepsy filter. Why is this suddenly a problem for me? Does the increased resolution cause these kinds of things with the epilepsy filter?
