Internet Explorer: CPU Usage: 49~53 FPS: 60
Node.js : CPU Usage: 35 ~ 38 FPS: 60
Chrome : CPU Usage: 65 ~ 72 FPS : 60
Game Image Memory : 49.7mb
I made a test to compare the CPU Usage now: It shows here that Chrome does use an awful of CPU compared to the others but not noticeable in my case. I really can't say more because of our test result difference but if there is something wrong with Chrome then we can't do anything but wait.
Though, It is quite surprising that IE beats Chrome.
