I had a few jitters but the jump mechanic seems entwined with the entire screen, I'm not criticizing maybe that's fine.
My table used WebGL
I tested on a lenovo with a 1.0ghz processor and 1gb ram. I got up to 26%cpu and as low as 18% with an average of 60fps, with drops down to 58fps after a jitter. and a massive drop to 48fps upon start of layout.
Again, you would of had to specifically select the c3 runtime to test the new set-up.
