The game/port has definately a bug on the VRAM. I started with 230MB free, accepted the Empire campaign, travelled to a lot of new galaxies (Moudar) and the VRAM ended up with only 15MB free (1024x768 24bit). For example, each time, I landed on a new planet to refuel my ship for a new space jump my VRAM got eatean around 10-15MBs. VRAM should be free every now and then. Hope beworld can take care of it because you have to restart the game every now and then and loading takes time away from the fun :(
