I installed Windows 10 via Bootcamp on my iMac Pro (8 Core, 64 GB Ram, Vega 64) and tested a few games and applications. Some of them are running great (e.g. Quake Champions), but some run extremely bad. Examples: - Doom (2016) is a slideshow, even the menu renders with 5 fps. - PUBG has sporadic but heavy frame drops. - Far Cry 3 crashes on launch I connected my Vive to try a few VR apps. While none of the tested apps stuttered, some graphic features were unavailable. For example, in "The Lab" (Valve) or "theBlu VR" (Wevr), many surfaces were rendered without advanced shaders, no bump mapping etc, so everything looked completely flat. All apps run fine under Bootcamp on my 2017 iMac 4,2 with the Radeon 580. Some have suggested to install the most recent Vega drivers, but the official drivers from AMD do not support Boot Camp (the installer does not recognize the Vega in the iMac Pro). Inofficial drivers from Bootcampdrivers or mXDriver are not available yet. So anyone who would like to run some games or one of the many VR experiences on the iMac Pro on Windows: It's probably a good idea to wait until Apple has released better drivers. Oh and by the way, I played some Fortnite on macOS with maximum details and it runs fantastic. However, the fans were really noisy while the game was running. I didn't expect that, as many of the early testers said that the iMac Pro is so quiet. Of course, it would be great if anyone has suggestions how Windows performance can be improved.
