Well guys, my comp specs are
AMD XP 2400+
512 DDR333 RAM
nVidia GeForce 6200 256Mb Graphics
Onboard sound

As you can see, below the specs but after patch 1.2 my FPS increased by 2 - 5.

Although I've never had the opportunity of having 20-30 FPS whilst on the bridge,

I now have 15 in Control Room 30+ on the map and 10-12 on the bridge. A major improvement on my comp from the 7 FPS I had on the bridge previously. The game is running relatively smooth for my standards. Of course I cannot relate to any other comp as I've never had a major upgrade thus far.

I run at 1024x768 60Hz
Environmental and Fog the other stuff except 3D ship wakes and Normal ship maps (still haven't worked out what this does) turned off because I get clouds, rain, and fog anyway with those settings off. I have v_sync on.

I don't loose any fps when it rains and foggy and overcast.
