What is your system like (cpu, gpu, os)?

The only situation in which canary gives me the result you are getting (dt's at whole number intervals) is when I run it full screen (F11). Don't know why that would be.

Please can I ask everyone to reduce the sizes of their screen captures - it's hurting my brain....

Ya, will do. Sorry 'bout that

Canary updated today to Version 40.0.2209.0 canary (64-bit). Tried your new test windowed and got this:

Seems like the new improvements work in window mode now.

Give the new canary a try?

The weirdness continues. I just ran Colludium 's second test, but with Canary windowed this time, and got similar results to eli0s:

The reason I tried it windowed? When I try to load the test with Canary maximized, it won't load (huh?). I have to make it windowed. However, after it loads I can maximize it and run the test, which gives me this:

I guess Canary's new V-Sync improvments only work with the browser maximized for now...

EDIT: Did you run you tests with the browsers windowed? If so, try them Maximized/Full Screen.

Just don't know what to make of that. What is your exact version of Canary (Toolbar -- About Google Chrome)?

Colludium

Could you post a version of your second test that only runs for 20 seconds? Or even lets the user specify run length?

Two approachs. One with instance vars for the array, one with globals.

Here, look at this:

Capx please...

And the rest...

Have you tried Canary yet? I ran your test and it confirmed my subjective opinion: Canary now vsync's about as well as IE.

EDIT: Whoops...you posted right before me...

Wow, that's really neat! I was looking around for something like this recently; my space based shooter would look great with an animated nebula in the background...especially since the working title is 'Nebular Drift'

Any way to get it moving?

Yikes. Is this for a game, or are you doing a database app? If it's a game, web-workers might let you offload the heavy lifting to another thread. That would require plugin work though.

Also, if you have a lot of objects, or are generating a massive amount of entries in an array/dictionary, debug mode can slow your project down radically, because it's creating a visual representation of all that data (even if you are not looking at said array/dict).

Any way to update your database across a number of ticks (limit the maximum number of operations per tick) like rho suggests? Sometimes browsers will crash or throw errors if you try to do too much in a single cycle.

Easiest way to do this is to use the turret behavior:
