Visionary Render 1.3.x constantly polled for new immersive device connections and would enable or disable the functionality when it detects a connection. Regularly doing this had an impact on performance and stability.
As of Visionary Render 2.0, the application no longer constantly polls for new desktop immersion devices. These should be installed and ready before launching Visionary Render. The system will still automatically launch SteamVR when enabling this mode, however, SteamVR needs to have already been installed and the HMD configured at some point prior to launching Visionary Render.
