Use quickres.ini, it comes standard with POV-Ray.

Sorry, I assumed that when you read "Command-line settings are: +w800 
+h450", you would realize that I was giving *all* command-line settings. 
  In other words, just the first frame (clock=0).

Well, I didn't expect it to be a "smoking gun" or anything, I just 
thought it would be an interesting example of 3.7 not behaving as expected.

Again, what really surprised me is that the sse2 build, running with a 
single thread, was still about 7-8 times slower than 3.6.
