Lucid HYDRA technology accelerates Eyefinity with NVIDIA GPUs
 

The idea is pretty straight forward: because Windows 7 sees the multi-monitor setup as a single contiguous display from the AMD graphics card, the HYDRA driver can accelerate it regardless of the complexity of the driver and hardware on the AMD side. The system on display was using a Radeon HD 5770 from ASUS to run the two monitors and also included a GeForce GTX 26+ graphics card in the secondary PCIe slot. This was of course all running on the MSI Big Bang Fuzion motherboard with the HYDRA 200 chip. The performance scaling ratio here about 32%. That's impressive (but not incredible) and it is tangible and noticeable benefits on a 3840x1200 display configuration.
