Too much information to process...
Latest driver: which one? There are at least 6 latest drivers and I didn't count drivers for different operating systems.
Operating system: not even mentioned. Maybe XP and blonde hair? Or Vista without the platform update? Maybe 7 or 8 and the problem is something else?
It must be kobolds again. I suggest you do what you should've done before posting the thread.
PS: C3 is a beta. It's also possible that your system is fine and it's the game f************ing with you.
