Hi, did you check the cpu frequency on both phones while the test was running? You can from the shell on the phone run the following command that check the frequency every second: while true; do cat /sys/devices/system/cpu/cpu0/cpufreq/ scaling_cur_freq; sleep 1; done
Maybe they have done some optimization on the 2d graphics part that makes everything use less cpu and as a side effect the cpu governor lower the cpu frequency in response of the lower cpu need. Maybe the cpu and the 2d hardware frequencies are related each others. I own a Nexus One and not a Droid but some 3D tests that make an intensive use of the gpu but not of the cpu run with higher frame rates if I do something that keep the cpu busy just to keep the cpu freq high (just as a test). On my Nexus One your test gives the following results and the fps is not steady but really variable: avg=53 min=35 max=70 Bye Michele On Apr 2, 7:29 pm, Phil <[email protected]> wrote: > I have observed a marked difference in frame rate of 2-D (Canvas) > graphics following a 2.1 update on the Motorola Droid.
