Gianluca,
it should.
But yesterday I found the way of avoiding flickering in the original method (Mode B, the one most similar to the stock working of the game). So now it's perfectly possible to record movies with Fraps (and basically any other program of that sort), because it didn't work in Mode A. So now we have these modes:
0-Stereo Disabled - Stock visuals and behaviour.
1-Stereo Mode A (the one appeared in V4, default, highly optimized, 5%-15% fps improvement, not Synchronized, no videocapture).
2-Stereo Mode B (the original v3 but now WITHOUT FLICKERING, perfectly stable. Synchronized, no fps improvement, videocapture mode).
3-Stereo Mode C (a variant of the V4 with an intemediate buffer, not Synchronized, no Videocapture, usually slower than Mode A).
4-Stereo Mode D (a two combined frames version that still doesn't work very good. Based in Accumulator Buffer, not universal).
5-Stereo Mode B- (the original v3 flickering one, for the nostalgics) Synchronized, only method possible to take independent Red / Cyan ScreenShots.
For those with TrackIR 6DOF, if you don't get the basic MOD working with the 6 axes, use the patched 6DOF set included in the .rar (read above for details).

Pablo
