So I've had a problem with my game since the beta version, a lot of characters and parts of the environment was pink/purple and the audio had a lot of problems (1 sound at the time). I've tried everything but wasn't working until I saw a thread that said the problem came from the dual CPU. The trick was to physically disable one CPU.
So I've done it in a easier way :
Go to windows, type msconfig , go to the boot tab, choose Advanced options and then just divide the numbers of processors by two, in my case 12 (2x12=24) and then reboot your computer (you're just disabling one of your CPU)
This fixed my graphic problems and I now run at 60-100 fps with no graphic and audio issues.
I hope this helped
Don't do it if you're not comfortable trying it and I'm not responsible for any damages to your hardware.
