I'm still learning the ropes, but the game seems to crash every once in a while with the following error.
DX Error: Invalid call
Everything else is in ordnung = hardware is rock solid, no other problems of any kind with any other software.
I used to know my hw configuration by heart, but I guess ones capability to remember things recedes with the hairline.
My display card seems to be Nvidia Geforce 8800 GT and I'm running some sort of Intel based platform with Windows 7.
I've had two crashes in about an hour and plus. So for time being, it is mostly an inconvenience.
