Reports are surfacing from XDA-Developers and the Google Code forums that the HTC EVO 4G has major framerate issues. It seems that the device is some how locked at 30 frames per second both in 2D (Canvas) and 3D (openGL) modes. Interestingly, the HTC Hero hits 54fps on average and has smoother scrolling in the menus compared to the HTC EVO 4G.
Why exactly is this happening? I doubt it is the hardware. Many at XDA and the Google Code forums are saying that it might be a major firmware fail. Hopefully this is fixed as soon as possible. It is kind of ridiculous to have the HTC Hero score better benchmarks than a device with a snapdragon processor!
First WiFi, now this? Is your EVO having any issues?
