Low FPS / Stutter FIX

Does Postal III run terrible and tend to freeze? Don't worry, this method should make the game run a whole lot better.

The method

The steps below should make this game run a whole lot better as Postal III was not really optimized for multi-core CPUs. You shouldn't run into any issues, and if you do, you can easily reverse the following steps:


1. Navigate to: C:\Program Files (x86)\Steam\steamapps\common\Postal III\p3\cfg\ , and open the "autoexec.cfg" file (if it's not there, launch the game once OR create a file with the same name).

2. Change the line "mat_queue_mode -2" (without quotes) to "mat_queue_mode 2" (again without quotes).
NOTE: as Steam user Toploader stated in the original thread with all of this information, it's likely the developers meant to type -1 instead of -2 which makes the game use queued single-threaded mode. Now, however, the game will run in multi-threaded mode and it'll hopefully give you a huge performance boost like it did for me.

3. 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 (I didn't need to add this line, but if you're really struggling with low FPS this supposedly disables NPC expressions whenever those NPCs are off-screen)

4. Once you've added what you want, save the file. That's all there is to it!!

Is it possible to make the resoultion go down less than 1024xsomenumberIforgotwhatitwas? It might make my game go faster but it will only let me go down to that

That sucks :(

It didn't my game run faster at all, just same slowness as usual.

Yes. To be fair, both Postal 3 and Bully are horribly optimized for PC so you can't blame your laptop entirely.

Is this guide meant for people who's Postal 3 runs incredibly slowly? I can't run high powered games like Postal III and Bully because my PC is total garbage.

Yeah, that can help in some situations. I hope you enjoy the game :)

Thanx! I have moved yet in the task manager on a core, now it runs much better. But if too many bodies lie around it jerks, nevertheless.

Odd. Because that looks correct to me.

You're very welcome. Hopefully the experience for you will be a bit better now.
