Portal 2 VR

Use this mod at your own risk of getting VAC banned. Use the -insecure launch option to help protect yourself.

Apparently Portal 2 doesn't have VAC, but just to be safe you should still run the game with the insecure flag.

This game contains flashing lights and fast motion sequences.

• Disable SteamVR theater in Steam settings

If the game is stuttering, try:

• Steam Settings -> Shader Pre-Caching -> Allow background processing of Vulkan shaders

If the game is crashing, try:

• Lowering video settings
• Disabling all add-ons then verifying integrity of game files
