Cyberpunk sneaky-shooty game Deus Ex: Mankind Divided got another patch today. The new version, 1.9 build 582.1_P9, adds official support for the DirectX 12 API that's been in beta testing for a month. Developer Nixxes originally intended to fully launch the DX12 codepath on September 19, but as it turns out, that goal was a bit optimistic.
Nixxes also meant to have DX12 multi-GPU support in for the official launch, and that goal appears to have been a bit optimistic, as well. The official release only supports single-GPU configurations. There is a beta branch (selectable under the Betas tab in Steam) that offers multi-GPU support, though. Nixxes has asked that users with multi-GPU rigs try out the beta branch and report any issues they encounter. As before, users having trouble with DX12 should simply switch back to DX11, because there are no gameplay or visual differences between the two render paths.
Besides the DX12 support, the new build also fixes some bugs. Diagonal walking will no longer cause Jensen to mysterious alert enemies, and the persistent shooting range crash bug should be fixed. The "Hold E" sub-menu prompts have been moved to the tab key to avoid interference with dragging bodies. Finally, some errors in a few missions' scripts have been fixed. Steam users should already have the new patch queued for download.
We're in the midst of a full-on review of Nvidia's GeForce GTX 1060 as of this writing, but some informal testing with this latest patch suggests that the pronounced stuttering on Radeons we uncovered in our early testing of DXMD's DX12 mode has been more or less eradicated. Some rough performance we experienced with the GeForce GTX 1080 under DX12 mode has been eliminated, as well. We'll be adding the game's DX12 path to our benchmark suite for that review, so stay tuned while we gather some data with this patch.
