I'm working on a CPU-intensive HTML5 canvas game that uses Createjs and Box2D.js
The game runs at half the frame rate on AMD-processor computers compared to similar spec Intel ones and I can't figure out why.
Is there any reason why CPU architecture would affect either Canvas, CreateJS or Box2D.js performance?
The game is an early prototype found at ==> http://niboon.x10.mx/deluge/game/
I have turned off the intensive custom shader before but there was still a big discrepancy between AMD and Intel CPUs.
Please toss any plausible ideas my way, I'm stumped.
