CFX/SLI Support

Unreal Engine 4 does, in fact, support a form of SLI. To quote from an article from Feb. of this year, "UE 4.15 introduces experimental support for HDR (high dynamic range) output, a new texture streaming system, and support for alternate frame rendering (AFR) in Nvidia SLI configurations." (Source)

4.16 just came out, which has further stuff for us, so we‘re eagerly awaiting to upgrade, although we‘ll be going dark for at least a month to upgrade. It would be longer if our sister team weren't handling most of the integration work, as they are building their game on top of our work.

Going black means no patches after we start. We can still run campaigns and so on, and enable content over time that has been deployed before that starts, but it‘ll be a dark costly affair.
