I have a I7 2600K and 2x GTX670 running in SLI. I tried to plug my monitor directly into the motherboard so I can take advantage of the great video encoding of the integrated GPU using LucidLogix Virtu MVP. I read that I would lose between 3% to 5% 3D performance. When I ran 3DMark I am losing more then half FPS. Do you know if I am suppose to do something else to increase my graphic cards performance? Thank you.
I think I found out the answer to my own question. The LucidLogix software does not work with dual GPUs (Crossfire/SLI).
That would make sense... LucidLogix Virtu MVP is great but introduces even more software/driver headaches, so it comes as no surprise that multi-GPU systems are not supported. I would have loved to use it too but I didn't even try because I knew it would just give me headaches.
