Recently, it was discovered that when we adjust the CPU frame rate from 20 to 30, the driver overhead will increase, from about 20ms to more than 30ms, and the swapbuffer time has not changed. What is the reason?
Hi Shawn,
It's impossible to say without more info. What are you measuring and how are you measuring it? If you are not CPU-limited time will be a poor measure on most mobile devices, as the frequency will be scaled to fit the time available. If this is "real load" the common cause is dynamic data reuse causing ghosts to be created: community.arm.com/.../mali-performance-6-efficiently-updating-dynamic-resourcesCheers, Pete
