When testing AMD 3D and NVIDIA 3D Vision we are quite limited in the scenarios where the two can be compared. This is due to the limitations of AMD's implementation which uses 3rd party drivers to enable the 3D effect. These 3rd party drivers lack the support and polish of the NVIDIA alternative and since we began testing this aspect of AMD cards around 8 months ago the situation has not improved significantly.
So we opted for Left 4 Dead 2 as our comparison as it is one of the few games we have seen work on AMD and NVIDIA hardware in 3D. We are using the iZ3D driver which costs $30 after the initial 30 day trial for this test as it gave us the best results on AMD.
Configuration and software issues aside the performance of the HIS Turbo allows us to play Left 4 Dead 2 in 3D at our chosen settings with decent image quality. We do need to tweak the stereo effect in our drivers before playing to get the best 3D effect though.
