I have a game built with Javascript and HTML <canvas> that utilizes the EaselJS rendering engine. After upgrading from Consumer Preview to the full version of Windows 8, my frame rate has been cut in half. I've tried enabling and disabling the use
of requestAnimationFrame with no change, and so far I haven't found any notes about major changes to the <canvas> implementation.
Has anyone else faced similar issues, or know of any possible things to try?
It's always possible that it could be an external issue (GFX driver, etc), but it will take a while before I'm able to cross those all off.
