Lately I've noticed that my frame rate in my app drop from 60 to 40. Any suggestions on a method for tracking down the problem?
The scene is pretty simple nothing animated in the scene just working on HDR rendering.
Ways to find cause of huge framerate drop?

Start with very sleepy: http://www.codersnotes.com/sleepy
Or gprofile on Linux.
For more details the new profiler in Irrlicht svn trunk can also help (you can even get some profile data from Irrlicht itself now if you compile it with a corresponding define enabled).
If it's on shader-side I don't know. Only thing I found there was measuring times - modifying code - measure time again - etc.

I'll checkout that app you posted. I not so sure it's shader as my scene only has a plane in it and a sky. I think it has more to do with using floating point render targets that might be the problem.
