I wonder if there's performance being left on the table because of the way programs and games are designed. It's no secret Qualcomm's mobile chips will run like shit when you try to use desktop code on them, because they're designed differently. I wonder if we're seeing aspects of that here. It would explain why Qualcomm convinced their press team of impressive numbers that nobody in the real world has been able to replicate.

There was a whole comic about design differences when porting desktop style games qnd shaders to mobile (I can't find it for the life of me) which was a pretty good beginner's guide to porting that stuck with me.
