framerates differences in browser and nodewebkit

I am wondering why my game runs so much smoother (framerate wise) when I export it to Node-Webkit, but it relatively choppy when I am testing it in the browser (any browser). This holds true for both my laptop and desktop.

I understand that when published to the desktop my game is essentially running on chrome which is wrapped in an exe.

Could spyware and other secretly running things in the browser be to blame? I am considering doing a clean install of windows but I want to know if it will be worth it <img src="smileys/smiley5.gif" border="0" align="middle" />

I've done some tests 4 different machines, and got a 50/50 experience.

Sometimes, Chrome is 40% fastest than Node Webkit, sometimes Node Webkit is 40% faster than Chrome. And it doesn't seem laptop/desktop related.

So, I guess it's just hardware related, and you don't have to worry about spywares or hidden software :)

Are you on a laptop? If so did you open your browser while running I battery power? On my laptop if you open certain applications(like browsers) while running on battery power it will throttle them to try and increase the batter length.

I know you can turn the setting off altogether. Ashley talks about it a bit here: scirra.com/blog/ashley/7/nvidia-hobbles-webgl-performance-on-laptops

If you're not running on a laptop I got no guesses. Good luck!
