Hi, i was curious to see whether the vsynch that is default on all devices is actually a hardware limitation of a software limitation. For this i first tried to get EGL_MIN_SWAP_INTERVAL. Neither EGL10 nor EGL11 expose that constant. Fair enough, the official EGL headers show me the constant value. I was surprised to find that my Hero has a EGL_MIN_SWAP_INTERVAL of 0. So you could in fact disable vsynch.
For that you need eglSwapInterval. Only problem is that it's not exposed in the Java interface. It is however in the latest r5 release of the NDK, the first one to expose EGL functionality on the native side of things. Is there any way to backport this to to native code for say a 1.5 device? Or a 2.1 device? I know that turning of vsynch is probably a bad idea on a battery powered device. But i'd still like to have complete control if at all possible. The LG Star (Optimus 2X) featuring that shiny Tegra chip seems to have vsynch disabled by default, running at higher framerates than the display is capable of handling (a lot more than 60Hz).
