    The Oculus branch of ETS2 & ATS now have experimental Vive support: http://steamcommunity.com/app/227300/discussions/0/648814844007204502/#p77

    To enabled it you need to use the -openvr command line parameter and also it is likely a good idea to disable the "Desktop Game Theatre" for the game as the game is not marked as VR-compatible in Steam.

    Currently there are several modes you might try to see which works best for you. They are controllerd by new config parameters o_openvr_independent_timewarp ando_openvr_interleaved_reproject

    • o_openvr_independent_timewarp set to 1, o_openvr_interleaved_reproject set to 0. This mode is the default one. It tries to do "poor man" asynchronous timewarp. Note that there is still some issue which I need to investigate so it might be crashing sometimes.
    • o_openvr_independent_timewarp set to 0, o_openvr_interleaved_reproject set to 0. Image is directly passed to the compositor. The compositor will try to run at 90fps and fallback to interleaved reprojection at 45fps when framerate goes low. If the game stops updating the screen for some time (e.g. during loading screen) the image will temporarily switch to the Vive room.
    • o_openvr_independent_timewarp set to 0, o_openvr_interleaved_reproject set to 1. Image is directly passed to the compositor. The compositor is forced to always use the interleaved reprojection. This is probably the mode to try if your system can consistently maintain more than 45fps. If the game stops updating the screen for some time (e.g. during loading screen) the image will temporarily switch to the Vive room.
