I know it will be choppy since i have a NVIDIA GeForce FX 5200, i have nvidia drivers and all settings on low.
And yes the only requirement i have a problem in is the graphics card, no other.
Though it's still playable, i just want to enjoy the scenes of the battles im in maybe 10-100 ships.
Is there any program or file i can download to decrease the graphics even more, or make it less laggy/choppy.           
I done this before when i was playing Earth 2160, there was a file i downloaded to make the game less choppy/laggy.
