And that, trucker, is the whole point.
You cannot just launch the standard Steam version of ETS2. The VR implementation is an open beta that has not been updated as frequently as the main branch.
Before diving into the setup, let’s address why you would choose a Pico 4 over a Quest 2, Quest 3, or a dedicated PCVR headset like the Valve Index for trucking.
| Issue | Solution | |-------|----------| | Game launches flat on monitor | Use -openvr launch option, not desktop mode. | | Head tracking drifts | Recenter view with F12 or remap key in controls. | | Stuttering / low FPS | Lower mirror quality, reduce scaling, disable in-game vsync. | | World scale too small/large | Adjust g_hmd_world_scale in config file (1.0 to 1.3). |
A: Go to config.cfg and adjust uset r_hmd_world_to_screen to your IPD manually (try 0.9 or 1.1). Alternatively, reset seated position via SteamVR (Long press menu button).
