This probably won't solve the problem, but you may as well try it anyway. Start the game in windowed mode and set the program's affinity to only one core instead of the default four.

ok thanks. how do i do that?

To set the affinity, first launch the game then Alt + Tab out of the game and open your task manager, find Postal under the process tab (if you cannot find the process go to the Applications tab and right click Postal 2 then select "Go To Process") then right click it and select "Set Affinity" and uncheck the boxes until only one of the boxes remains ticked.
