[Qemu-devel] GTK: default display refresh rate at 60Hz

[Chen Zhang via Qemu-devel]

Hi,

It’s observed that GTK display performs poorly compared with native 
environment. The display refresh timer fires at a interval of 
GUI_REFRESH_INTERVAL_DEFAULT milliseconds which is defined as 30 in 
include/ui/console.h. This throttles refresh rate to 33Hz.

Changing its value to 16 (i.e. 60Hz) seems reasonable and may actually improve 
performance.

Best regards
