An HTC represesntative in attendance at the HTC Aria event in Chicago last night, reportedly provided some insight into the 30FPS limitation that has been reported on the HTC EVO 4G. As was suspected, the 30FPS limit is imposed via software, but it is a hardware limitation that lies at the heart of this issue. Though the smartphone is capable of much more than 30FPS — as shown above — the EVO 4G is throttled down to support the 30FPS limitation of the HDMI hardware that is included on the handset. EVO 4G owners will be stuck with 30FPS on all their games until HTC decides to throw in some code to dynamically adjust the FPS based upon the presence or absence of an HDMI cable. Of course, there is always the folks at xda-developers who have already been working on this limitation and most likely have some hackery already on-hand that will give you both 30FPS HDMI out and 60FPS gaming.
