Dear Faisal Ali,
Dear Faisal, Since the HTC EVO 4G employs a unique HDMI output to deliver video in HD quality to an external display, the hardware graphics driver interface on the HTC EVO 4G uses significant resources for the HDMI output and therefore displays graphics at 30 frames per second on the integrated display. This is a hardware, and not a software, limitation. It’s important to keep in mind that content including most movies and television, are created to run at between 24 and 30 frames per second. The 30FPS is a hardware limitation. We have found that some games may be impacted by this limitation. If you have any other questions or concerns please Reply back to this email or give us a call at our HTC Technical Support Line, 1-866-449-8358. I want to thank you for contacting HTC.
