Vietcong & G450 ... very, very slow...!?

[netdh]

Does everybody have an idea why "Vietcong" is running realy very slow on my PC (G450, P4 3Ghz, 1Gb) . Other games (Freelancer per example) are running in absolutly correct manner.
Thanks!

Try lowering the settings to a minimum. (G450 not a gaming card)
