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

I understand what you are saying about the perpendicular surface optimization but to me it seems more a progressive behaviour related to the angle. Actually I was mistakenly using 32 bit textures but I changed them to 16 bit ones and the numbers remain the same. The square is large as the

Thank you for the reply and the suggestion. It seems to me that changing the mag/min filter to nearest was a test I've already done in the past together with other combination of options but I retested it anyway and there is a slight improvement that is the fps at 90° pass from 8 to 11 for the 1

2010-03-01 Thread Michele Scorcia
Hi, I've found that if I rotate a square textured with a 512x512 texture by 90 degrees, the frame rate goes from 60 fps in the case of the 0 degrees rotation to 8 fps in case of the 90 degrees rotation. Just to be clear the difference between the two cases is just a value of 0 or 90 for angle in
