So "GX" should be turned on when playing Openal games (ie Stalker: CoP)?
I've seen Talons/Eclipses that could beat that Lambo......nothing impressive performance wise.
Creative Vision: M 30GB....in ultra cool mind bending black of course.
I would also check your alternator output voltage. Should be 13.8 - 14.4 with the motor running. Check your electrical system ground for corrosion...
