There have been issues of performance being poor on KYRO II based video cards. The good folk over at the PowerVR Rev forum, (a member named dfua) has found a quick solution.

Enable defer render until flip, and don't show any framerate counter. Enabling the framerate counter drops framerate by almost 95% on KYRO II based systems. Can you guys check it out?
