Modern mobile devices and smartphones are reaching the computing capabilities reserved until recently for desktop PCs. Windows 10 phones and tablets with 8 CPUs and very powerful GPUs are expected soon. Despite significant progress in reducing power consumption these devices are able to draw more power under sustained load than can be safely dissipated with current passive cooling technologies. Windows 10 and the hardware it runs on are designed to safely handle such situations, mostly by reducing the system performance — which could affect game-play negatively. Learn to counter this effect by designing games that achieve sustained thermal-to-quality tradeoffs in these systems.
