Edit -> I can get some basic tinting working, then it fails and reverts back. Also enabling WebGL gives me a 50% reduction in performance, and no noticeable performance increase in canvas performance on ARM. Pretty disappointed atm.
Getting the following errors with WebGL enabled:
WEBGL11095: INVALID_OPERATION: validateProgram: Method not currently supported
WEBGL11094: INVALID_OPERATION: texImage2D: Enum UNSIGNED_SHORT_4_4_4_4 is not currently supported
Edit-> For anyone trying to install Windows 8.1 on an English GB device, you'll have to reinstall Windows 8 and select a different language on install. I chose Dutch. Then you can install fine and change language after.
