But there will be no 85 FPS either, because buffer flips will be synchronized with the monitor vertical refresh (assuming that fb0_framebuffer_num is set to 3 in fex and /var/log/Xorg.0.log does not complain about problems with zero-copy buffer swaps).

Quote from: wickwire on October 17, 2013, 08:33:26 amWith ssvb's help, I managed to get a stable Qt5 Cinematic Demo running, I had to set the memory clock speed to 384MHzu-boot-sunxi from git, find the board/dram_cubieboard2.cand adjust the speed from 480 to 384and then burn it on the SD Carddd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8update: this instability issue seems to only affect about 20% of cubie A20s around, guess mine is one of those - so "underclocking" the dram clock speed solved it for me.
