Tell them to have a look into this thread ---> http://www.gamesas.com/index.php?/topic/1236685-ram-and-cpu-detection-problem/ - looks like the auto detect isn't working properly, many people reporting the game detects their CPU is 3MHz and they have 0 MB of video RAM.
Enable console via the launch options button: +set com_allowConsole 1
Open the game, open the console, then scroll to the very top. For most people (myself included), it says I have a 3MHz CPU installed, and 0 MB of video RAM.
Is this the reason for the incredibly shoddy PC performance?
For reference, here are a few of my PC's specs:
Core i7-2600k (Overclocked to 5.0GHz)
16 GB RAM
nVidia GTX 590
