Samsung Odyssey, first thoughts in Virtual Reality Posted May 28, 2018 yes you need steam, it uses steamvr. Stand alone works fine but it needs to launch steamvr Yep exactly. I'm DCS non-Steam user. What I did to make it run: - Configured the Windows Mixed Reality environment as instructed when plugging the headset. - From Steam, installed "Windows Mixed Reality for Steam" (had to search manually for it in the store) - When I play, I first start "Windows Mixed Reality for Steam" (which also starts the WMR envirnment), I wait for the headset to hook up and then I start DCS, works like a charm.
