Disable V-Sync (option)

Edit xorg config, add Option "Dri2Vsync""FALSE" to /etc/X11/xorg.conf.d/20-modesetting.conf

Section "Device"
Identifier"Rockchip Graphics"
Driver"modesetting"
Option"AccelMethod""glamor"
Option"modesetting""2"
Option"Dri2Vsync""FALSE"
EndSection

Then reboot the system, let xserver loading new config.

Set CPU governor to ondemand (option)

Set to ondemand

echo ondemand | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

Reset to interactive

echo interactive | sudo tee /sys/devices/system/cpu/cpufreq/policy0/scaling_governor

* We need set TinkerOS’s CPU governor as same as Competitor SBC.

** TinkerOS default enable V-Sync technology to provide a smoother vision experience. V-Sync technology can prevent frame rate stuttering and screen tearing depend on the display device and GPU, software in use, and the nature of the video material.
But if we need to compare with Competitor SBC, we need to set the same setting with them.

*** Some platform do not load GL driver on default, because the GL driver may still be developing not official release.
