@kmega99:
You should reduce the polycount on your ship.
It's too much detailled ,specially if you want 50 or 100 ships at screen (you'll have to use LOD also).

Your actual version should be for cinematics or very close
camera view !

Don't forget you'll have HUD, path finding, network, 3D special effects etc ... all that running at same time.

For the rear cylinders elements of your ship you shoudl have :
- 8 or 10 side cylinders for close view
- 5 or 6 sides for mid range
- 3 Side for very far range (or another type of optimisation)

Perhaps you can make it detailled like now, then use it like that in your game ; than decide after if you have to weld vertices to decrease the polygon number depending on frame rate.

Don't forget :
Your model don't need to be so rounded, faces smoothing and shaders will make it smooth on surface even without beeing well rounded !

Here is what i made in 10 minutes maximum :


You can see it looksvery similar to your ship model !
But the polycount is very low compared to yours



Even this polycount should be for close views or near, for distant it should be reduce a lot !
The texture and shaders will make all the work to make it look very detailled and rounded.
