The short version
Does the NVidia Quadro NVS 450 have more than one GPU in a single card?
The long version
I'm setting up Linux (Fedora 19) on a work computer which has a NVidia Quadro NVS 450 installed. I have set up the NVidia drivers (the nvidia module rather than nouveau) and am running Gnome 3 with 2 screens. However I've found that the performance is weak compared to even my old GeForce 8600 running Gnome 3. I found an old post about the Quadro NVS 450
which suggested that the card has more than one GPU and that Linux might not detect the second one properly, since I don't know much about the card I was wondering if that was possible?
