Also, the text object is differenced from a plane. Since a plane is 
infinite, the combination of plane - text object is tested for every 
pixel. If you used a large box instead of a plane, you would probably 
notice a big increase in rendering speed, since the object can be 
bounded so it is only tested for in a specific area. To possibly get 
even more of a speedup, use a separate box for the area with the text 
object differenced from it, and surround it with other boxes to create a 
seamless floor.(confining the area with the text object CSG to as small 
an area as possible)
