The Deus Ex: Mankind Divided patch released today doesn’t come with the usual set of patch notes, as it appears to be addressing one thing: SLI support in DirectX 12 mode. If you have a pair of DX12 capable Nvidia cards, you should be able to now harness both of them.
“Today we are officially releasing Multi-GPU support for DirectX 12 for NVIDIA GeForce users. This will mean that the dx12_mgpu_preview Beta branch will be removed,” the announcement reads. It adds that you’ll want to be using the latest Nvidia drivers (375.86) to be the most out of this update. You’ll also want to “confirm that your SLI is active in your NVIDIA Control Panel”.
Nixxes added DirectX 12 support to Deus Ex: Mankind Divided back in September.
