The PC release of Halo: The Master Chief Collection will not support either SLI or AMD Crossfire dual-GPU setups.

Revealed through a blog post on the Halo Waypoint blog, the PC release of the Halo collection went support dual-GPU configurations.

While no reason was given for the lack of support on PC, we can assume that its due to the sheer amount of engines that run in the collection. With original engines for the six Halo titles alongside two remastered engines and an Unreal Engine 4 customisation engine, there’s a lot to work on. To get flawless performance on all nine engines is a tall task for any developer.

Thankfully, 343 Industries has said that PC performance is shaping up well for single GPU setups.

“We have been in talks with several video card makers to ensure we have as many cards as possible being supported for MCC on PC through both our efforts and theirs,” 343 Industries revealed.

“At this time, we want to let PC users know that Nvidia SLI and AMD Crossfire graphics card configurations will not be officially supported in MCC on PC. During our work back and forth with the card manufacturers it was determined that the performance offered by single card setups was high enough that SLI and Crossfire configurations would not be needed.”

Halo: The Master Chief Collection on PC is still a ways away until completion. While the series’ pride and joy Halo: Reach should be releasing before the end of the year, the rest of the game will be releasing piecemeal over the course of the year.
