1. Download L4D2VR.zip and extract the files to your Left 4 Dead 2 directory (steamapps\common\Left 4 Dead 2)

2. Launch SteamVR, then launch Left 4 Dead 2 with these launch options:

   -insecure -window -novid mat_motion_blur_percent_of_screen_max 0 crosshair 0 -w 1280 -h 720 mat_queue_mode 0 mat_vsync 0 mat_antialias 0 mat_grain_scale_override 0

3. At the menu, feel free to change these video settings.

4. Load into a campaign.

5. To recenter the camera height, press down on the left stick. To see the HUD, aim the controller up or down.

• The host must have the mod installed and the server must be set to local. Other players can play in VR too (if they also installed the mod).
• To host a local server, click Play Campaign -> Play With Friends -> Create new campaign lobby -> Server Type: Local Server
• You can make your game public if you want.
• Versus works but it's barely been tested.

If the game isn't loading in VR:

• 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
• Re-installing the game

1. git clone --recurse-submodules https://github.com/sd805/l4d2vr.git
2. Open l4d2vr.sln
3. Set to x86 Debug or Release
4. Build -> Build Solution

Note: After building, it will attempt to copy the new d3d9.dll to your L4D2 directory.
