I think Martin has profiled this problem and should have good data. http://faunalia.it/pc

I have done some tests and rendering with reprojection takes obnly about 10% more time. I was convinced that it must be quite time consuming. In fact, reprojection is a complex caclulation so I am wondering what can take so long time in rendering process so that the reprojection is not significant.
