COd just went from 10fps to 40.

Changed my config as suggested and did seem to get some improvement in fps and smoothness. After the computer had been turned off and I restarted the game I found the objects had gained icons when they were turned off before and also some dialogue windows had suddenly appeared. I turned off the icons again in options and that got rid of the windows as well. I think the improvements are still there but they are not very large, maybe 5 fps or so but noticable.

Thanks for the tip.
