Nvidia discontinues in-house support for three- and four-way SLI
Fans of extreme graphics setups, get your handkerchiefs ready. Nvidia is largely killing off its in-house support for three- and four-way SLI today. First, some background. During its Pascal announcement, Nvidia announced a new SLI HB (for "high-bandwidth") bridge that would be required for optimal GeForce GTX 1080 SLI performance at high resolutions. Later, in its GeForce GTX 1080 whitepaper, the company advised that two-way SLI would be the default supported multi-GPU configuration, and that three- or four-way SLI would require signing up for an "Enthusiast Key" that would need to be loaded into a GTX 1080 somehow. That website never materialized, and now Nvidia appears to be dropping three- and four-way SLI support from future SLI profiles altogether. In a statement to PC Perspective, the company said that it's "focusing [its] efforts on 2-way SLI only and will continue to include 2-way SLI profiles in our Game Ready Drivers."
