These days, I'm trying to solve performance regression problems. I implement my own performance counter and on screen graph. And I use Tegra Graphics Debugger and Tegra System Debugger. Finally Street Fighter Zero 3 back to 60fps.
It's very important showing what's going on inside.
I'm renting ASUS ZenFone2 for a month. a few fixes make uoYabause running on this device. But I found performance issue I may solve. I'll finish it, then release.
This is the BIG change for you can choose a game easily and delightfully. You can also choose game iso image directories and back ground image on setting menu.
