Thread: Flash Player Lags

Open the error console in Firebug, perhaps the flash plugin is throwing errors.

Is it possible that you have multiple flash players rendering the same thing? Open your process tree and be sure that Quicktime or Real Player isn't running behind the scenes. Trying to render the flash with two different programs at once would certainly cause a lag.

Nope, I'm just rendering it in my browser (Firefox at the moment). And how do I check if the flash plugin is giving errors?

Also, here's a CPU graph of Firefox while playing "Use Boxmen" on Onemorelevel.com:


The sudden drops in CPU usage is where it suddenly isn't laggy, and as you can see, they're very short compared to when it does lag.

What I meant is it might be possible that the last time you updated quicktime or something, it hijacked the flash rendering. Maybe your browser is trying to use both quicktime and flash at the same time. Do a ctrl+alt+del and look at the processes.

Nope, Quicktime isn't running.

Reset your browser to the defaults. Something is running along side your flash plugin.

But it does this in all browsers I've tried.

Uninstall flash, the remove all traces of it from your registry, then reinstall. When reinstalling and uninstalling, Windows leaves a ton of stuff behind in the registry, possibly including some settings.
