Everything in this game seems to work, however rendering to screen can be so slow
it makes the title anything less than enjoyable to play ; some would consider it
unplayable (certainly docking & tug boat operations suffer badly)...
The only things I have discovered that help, is to turn off all graphics effects
in the ingame video options menu, decrease the draw distances to minimum, and if
you don't overlay the controls that helps a little as well. However, even after
doing all this (and lowering the screen resolution itself), the best I was seeing
was 5~10 frames per second on a 3.2gHz quad-core with nvidia 9800gt/1024mb.
