Since I changed the nVidia card to GTX 285. On the screen during start game or switch it off game. Began to appear a strange "noise/glitches".
The problem is only in games. "Noise/glitches" after a while they disappear automatically. Some games do not have that "noise/glitches". The problem occurs from the beginning - no matter what my drivers (apple or nvidia).
Game that has a problem with "noise/glitches" when i run it in windowed mode - working properly. This problem occurs only in full screen mode.
MacOS 10.6.7 64 bit
GTX 285 1 GB
nVidia latest driver 256.01.00f03v7
