no under the differents browser on my PC windows 7, is really fluid i have no problem at all, my problem come when i export witth cordova, and after inside intel xdk i compile to crosswal android.
my game has just 1 level with 1 sprite, and just moving platform, how this is possible?
i mean when you look at some games 1gb in size hundred of ennemies the game stay very very fluid, no lag at all,
in my little game 800x480px with 1 sprite and moving platforms its terrible sloow.
