Performance drop

So Firefox and IE are fine? So it must be a Chrome issue, not a C2 issue. I'm reading there may be some issues with the latest Chrome 30 update: http://www.html5gamedevs.com/topic/1589-chrome-30-performance-drop/ - hopefully they'll have it fixed soon...

Actually, I can confirm: Chrome 30 drops most games to 30 FPS instead of 60 FPS. The workaround in that thread is to disable GPU compositing. Firefox and IE are fine still at 60 FPS, so it's definitely a Chrome issue. Perhaps your system restore put you back on Chrome 29.

Thanks! It's a Chrome issue. I updated it now and my game works!

uh-oh. Hope this doesn't roll over to Node-webkit.

Many thanks for the head's-up on this issue!

We'll avoid the version of node-webkit that is based on Chromium 30 to try to avoid this affecting it. If we just skip over to Chromium 31 hopefully it will be OK.
