Key points

Poorly optimized and very buggy, to the point of being officially disavowed by series developer Running With Scissors.[1]
For Windows 8.1 and later use POSTAL III NODRM to fix DRM compatibility issues.[2]

Name Notes
Fart Gun / Гамамёт Was originally a pre-order bonus for the Russian release of the game.
Later updates of the game broke the addon; fans responded by making a free remake of the addon that also works on the English version, available here.

Issues fixed

Game doesn't work on Windows 8.1 and later

Postal 3 has issues on Windows 8.1 and later due to the DRM being incompatible.


Various game mechanics such as throwing grenades, using human shields, etc. can crash the game with the NODRM fix. Various solutions for this exist, but most of them are not guaranteed to work. However, an grenade fix is available here as part of Sourcemod Template, which has been tested and worked with -game p3_gcf launch options.

FPS is unstable/game is laggy

Edit the autoexec.cfg[5][6]
  1. Go to the configuration file(s) location.
  2. Open autoexec.cfg (if it's not there, launch the game once).
  3. Change mat_queue_mode -2 to mat_queue_mode 2.
  4. Next, add the following lines anywhere you'd like:
  • physx_enabled 0 (the only noticeable thing this does is that it make the Postal Dude's jacket less flappy but it'll still move about, prevent animation problems and give the user a decent performance boost).
  • r_threaded_particles 1 (this allows for the game's particle system to be multi-threaded)
  • r_threaded_renderables 1 (this allows for the game's rendering system to be multi-threaded)
  • snd_mix_async 1 (this allows multi-core CPUs to run the sound engine with the renderer simultaneously)
  • ai_expression_optimization 1 (disables NPC expressions whenever those NPCs are off-screen)
mat_queue_mode determines the threading mode the material system uses. A value of -1 uses the default for your system, a value of 0 uses synchronous single thread, 1 uses queued single threaded mode, and value of 2 uses multi-threaded mode. The default value is -2, and reading the translated Russian within the default configuation files reveals that this was intentional: multi-threading breaks Postal 3's PhysX implementation when turned on (the coat detaches from the protagonist, along with other physics bugs).

  1. 1.0 1.1 When running this game without elevated privileges (Run as administrator option), write operations against a location below %PROGRAMFILES%, %PROGRAMDATA%, or %WINDIR% might be redirected to %LOCALAPPDATA%\VirtualStore on Windows Vista and later (more details).
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/10220/ in addition to or instead of this directory. The app ID (10220) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
