I haven't checked to see if this is the case specifically in the Tizen
environment, but in other WebKit based systems most CSS transformations
aren't hardware accelerated by default. You have to use a little hack of
specifying a Z translation of 0 ("translateZ(0)") to force them in to a
3D context in which they can then be accelerated.
None of the demo games that I've seen implement this optimisation, and
so can end up with quite poor performance.
I made a quick comparison video showing the improvements possible with
the hangman demo (running under TizMee, my Tizen compatibility layer for
You can grab my modified version of the hangman app here:
Which might help you to find out if this hack will be of assistance on
