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
