Hi,

I made a few fixes to my demo, and it now appears to run on par with Java. It seems I made a very rookie mistake on my main demo loop.

Check out Blaze demo #3: http://svn.dsource.org/projects/blaze/downloads/blazeDemos.zip

Cycle through (with arrows) and compare it to the Java pyramid stress test: http://www.jbox2d.org/v2demos/

Thanks for all the suggestions..... Although I may still take a stab a profiling to get even better performance! :-)

Maybe if you have spare time, you could write a blog post or article on performance gotchas you encounter while porting?

Why do you use lines with a thickness of 2?
Antialiasing too may be good.
Have you tried to compile it with LDC on Linux?
