I do believe I've found out how to get a true delta time, and it doesn't even require an update.

First number number is dt

Second is FPS generated from it

Third is the internal fps expression.

EDIT: Would everyone be willing to test these in your browser?

"Get Milliseconds" Delta

I can't offer the .capx for the second one. I had to monkey rig construct to make it.

That's interesting, it looks like some browsers have a high resolution timer on their ordinary time expression. I didn't realise they did that! I only tried Firefox 4 though.

Have you tested this on a range of browsers? I'm not sure if all modern browsers implement this.

I'm a regular Chrome user, and it works fine there. I couldn't tell you about the rest. But I originally got the idea from studying a list of javascript time commands. I realized while toying around with it that I was getting a much more precise number than expected. I wonder if getmiliseconds() could offer a universal solution if there's compatibility issues with the way I have it implemented now.

EDIT: Chrome version is 11.0.696.16 beta
