Now in 2004 NVIDIA has introduced their new SLI technology, but note that it does not stand for Scan Line Interleaving. This new technology is called "Scalable Link Interface" or SLI for short. Of course all of us old timers still get excited when we hear "SLI" and NVIDIA knows this. The new SLI is possible because of the new PCI-Express bus that was introduced last week. NVIDIA is telling us that when used with the Unreal3 engine, they are seeing increases in frame rate of up to 87%. To qualify this statement, I think it is needed to note here that an engineer stood behind this statement, not just NVIDIA's marketing department.
