 - Install SteamVR
 - Download the [latest release](https://github.com/oneup03/VRto3D/releases/latest) and copy the `vrto3d` folder to your `Steam\steamapps\common\SteamVR\drivers` folder
 - Edit the `Steam\steamapps\common\SteamVR\drivers\vrto3d\resources\settings\default.vrsettings` as needed
+	- Set your window resolution to your full-screen resolution (i.e. 3840x1080 for Full-SbS or 1920x1080 for Half-SbS)
+	- Set your render resolution per eye to what you want. Can save some performance by reducing this if you're running a half-size 3D
 - Run SteamVR at least once to verify that you see a Headset window. This is usually not needed before running games.
 	- The Headset window must be on your primary 3D display
 - Try launching a VR game
