Reports are flying in from across the internet -- and by that we mean the xda-developers and Google Code forums -- that the EVO 4G might have something of a framerate issue. It seems that the device is "locked in" at 30 frames per second both in 2D (Canvas) and 3D (openGL) modes, while anecdotally, a phone like the Hero hits 54fps on average and has "smoother scrolling" in the menus. This apparently is visible both with the standard Sense UI installed and with the Froyo preview build, although in the latter case the Nexus One bootup video is 60fps before halving upon reaching the home screen.
So, wherein lies the culprit? For Google's part, Android framework engineer "Romain Guy" responded to one thread reasserting the platform team's "target was, is and will be 60fps." We can't imagine it's related to the hardware given the EVO's impressive specs. Some fingers, ergo, are being pointed towards firmware. This wouldn't be the first time HTC's handsets have come under scrutiny for troubling graphical performance -- 2008 was not the company's finest year in that department. Whatever the reason is, we just want a quick resolve -- after all, it's just not fair when our Hero-carrying buddies are scoring better benchmarks.
