After a delay of a few seconds you will be presented with a breakdown of your FPS with various game options enabled / disabled. Use this information to help you tweak your FPS.
kpix shows the benefit of reducing screen size / resolution
no Diffuse shows the benefit of disabling diffuse lighting
no Bump shows the benefit of disabling bump mapping
no Specular shows the benefit of disabling specular lighting
Driver overhead, if this is high it may point to a driver issue
