Doom 3 lockups in stereoscopy
I have a laptop with a GeForce 6200 Go video card, and the latest (=78.01) stereo 3d drivers installed.
I noticed some strange lockups when playing Doom 3, which always occur in the same places. For example:
1) when you meet the first revenant and you go up the balcony to shoot him from above
2) in hell, when you look at the wall where the first hell knight of the level will appear
3) in hell again, when you look at the berserk powerup

If I play in stereoscopy and I reach one of the aforementioned situations, the image freezes and the sound starts looping. Sometimes I can unlock the game by disabling stereoscopy, if I hit CTRL-T fast enough. Most of the times, though, Doom 3 crashes after a while and I return to the desktop with a flickering screen. The crash report states that the problem is in nvoglnt.dll. This problem does not occur at all if I don't play in stereoscopy.

Is it a solvable problem?

EDIT:
I might need to add that the problem is strictly related to where I am [b]looking at[/b] in the game. I made the following test:
1) I entered the level "game/hell1" in stereoscopy. Everything ran fine until I reached the corridor just before the part where the hell knight should appear.
2) I disabled stereoscopy and turned 90 degrees to the right, straight toward the wall hiding the hell knight. Everything kept running fine, so I turned 90 degrees to the left, so that I'd have the "hell knight room" to my right.
3) I enabled stereoscopy again and SLLLOOOOWLY turned to the right. As soon as a glimpse of the wall hiding the hell knight entered the screen, the game promptly locked up.
4) Quickly, I disabled stereoscopy, unlocking the game.
5) I proceeded to kill the hell knight, playing WITHOUT stereoscopy.
6) I enabled stereoscopy again. Now that the hell knight was dead, everything was running fine.
