Exposed: 5 methods to create game loop: which is the best?

Edit: fixed broken links

What is the best method to create a game loop?

I created a small experiment comparing 5 different animation methods.

The results, along with code samples and test screenshots are summarized in this document:

5 Game Loops in Silverlight: Which is the best? (PDF)

5 Game Loops in Silverlight: Which is the best? (DOCX)

Sample test app (requires reading the document above to understand the setup): https://nokola.com/gamelooptest

This is part of the test app startup screen before measurements begin:

I hope this will shed some light on Silverlight game loop that several people on this blog asked so far!

Please let me know what you think!

    Nikola, I'm anxious to see what you have found, but the links to your document seem to be broken.

    Hmm... I get 404 errors when I try to download either version of the documents.

    I can't reach livefilestore.com. Can you make the docs available somewhere else?

    I have much much lower aveage with CompositionTarget.Rendering than any of the other examples, probably because it runs with a greater framerate for me. But thats the great thing about that loop... you only set the translate when you need to, and as often as you need to; no more, no less. Also I noticed that if I drag the browser window around, the stability of the other methods are all over the place, while CompositionTarget stays constant.

    Your links are broken... again.  Would really like to have this information.  Is it possible to just cut-and-paste the info straight to the blog and not worry about it?

    Hi J, I'm sorry that the links didn't work for you. I just tried them now and they take me to the right .docx/pdf file- what is the error message that you see? I'd like to just be able to copy-paste the info in the blog too, but unfortunately this blog has a restriction - 1 picture per post and some other formatting restictions which makes this very hard... Thanks for the patience and sorry that the links didn't work! Please let me know if they work OK now?
