I didn't want to make the thread title too long, but;
If you have MSI Afterburner enabled like I do, you won't be able to launch the game. You have to reset your settings, then close Afterburner. THEN launch the game, then alt+tab out, and relaunch Afterburner and put it to your stable settings.
If I do not use MSI Afterburner, the game freezes up and crashes. So it is required that I use it.
But, I'm not sure if that's causing my second problem;
About 20-30 minutes of playing in any multiplayer server, I will crash. I don't know what else to do. It just stops, I can hear some sound from what I was already doing, but then it just stops. I have to Task Manager and end process to get out.
Specs:
i5-2500k 3.30GHz (4CPUs), ~3.3GHz
4GB Ram
Windows 7 64 bit
nVIDIA 570GTX overclocked to I don't know what.
It's a great Alpha, don't get me wrong, but the optimization, and a hazardous amount of bugs are going to get people wanting refunds back.
