Other information

Launch parameters

You can launch Zombie Panic! Source with launch parameters - these parameters dictating how certain aspects of the game behaves (outside of gameplay).

Launch parameters are typically prefixed with - (dash), however you can also set console commands by providing the console command with a + (plus) prefix.

How to add launch paramaters^{[citation needed]}
Find Zombie Panic! Source in your Steam Library. Right-click the game name. Select `Properties`. Select `Set launch options...`. Add your launch parameters and press `OK`. Next time you launch the game the properties will come into effect.

Useful launch parameters

If you experience stuttering disable Windows Aero from the video options menu.

Parameter	Description
`-autoconfig`	Restores video and performance settings to default for the current hardware detected. Ignores settings inside any .cfg files until this parameter is removed.
`-console`	Starts the game with the developer console enabled.
`-dxlevel xx`	Forces the game to launch in a specific DirectX version, where `xx` is: "80" = DirectX 8 (however this is potentially buggy, use 81 for better performance) "81" = DirectX 8.1 "90" = DirectX9 with Shader Model 2 "95" = DirectX9 with Shader Model 3 "98" = DirectX9 on DirectX10 hardware Shader Model 4 Remove this argument after starting Zombie Panic! Source once or it will keep reseting your other settings.
`-h height or -height height`	Forces the engine to start with resolution set to `height`.
`-w width or -width width`	Forces the engine to start with resolution set to `width`.

Console Commands

Games running on the source engine can utilize Source Engine Console Commands for various tasks.

These commands can be saved into <path-to-game>\autoexec.cfg to be executed when the game launches.

Enabling the console in Source games^{[citation needed]}

Launch the game.
From the main menu select Options.
Select the Keyboard tab.
Click the Advanced button.
Check the box next to Enable developer console (~).
Click Apply.

Notes

Press ~ to open the console.

Some commands may first require you enabling sv_cheats. You can do so with sv_cheats 1.

Many servers will not allow you to play with cheats enabled, or will disable them upon entering the server.

Users without a US keyboard could experience some problems.

Useful console commands

Command	Notes
`net_graph 1`	Can be used from 1 to 4 with higher numbers providing more information. This code enables you to view in-game FPS, ping and more. There may be a performance loss from using this.
`ping`	Shows the ping of all clients connected to the server in the console.
`cl_showfps 1`	Shows the frames per second, 1 = exact frames per second, 2 = average over the last second.
`snd_async_fullyasync 1`	May help you are experiencing freezes when some sounds that aren't cached are playing. Allows sounds to play when ready if loading it is too slow, instead of freezing the entire game until it is.
`fps_max 144`	This code sets the maximum frame rate for the game and it can be changed to any value up to one decimal place, in this example the maximum frame rate would be 144.0 fps.
