Stuttering, Small freezes and framerate Issues

[plutomaniac]

Have you tried different settings at .cfg file for StreamBufferSize? You have to proceed with 1024 intervals meaning 1024 -> 2048 -> 4096 -> 8192 -> 16384 -> 32768 (stutter5fix current value).

As I already said, you don't have to uninstall the game every time. It's not needed and you are getting tired for no reason. You can simply edit your current main_settings.cfg with the values mentioned above (first try 4096 & 8192 as lower than that will most probably cause sound issues), make a new profile and start a new game.
