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:

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? -- Daniel

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?
