First, can you confirm that you still don’t get this artifact with other 3D software in conjunction with your triphead2go device? It seems to be an interaction between the triplehead2go drivers, your display drivers, and possibly Vizard. This will be difficult to replicate without the exact same hardware.
Second, it’s a bit of a shot in the dark, but have you tried exporting the IVE with DXT1 compression?
