I think, there will be no need at all to port a game to an ARM architecture very soon. The chinese market is floated with tablets/phablets supporting win 8/win 10. People are playing dota 2,team fortress and CS:GO on those devices already.
if the bge has the shader model updated,and a android compatility shader mode is added, and then multitouch is added, and some library work is done, then any game will be able to be exported.
I am told it will be alot of work,
but…
The render being updated is on the developers radar for sure, but
I have seen no plans.
there is talk of ‘rethiking logic’ but I have not seen any plans.
about libraries, I am just going off what I have been told, and I don’t know anything specific.
