I’m not sure what the expectation is here?
I might point out that game engines in general don’t work like regular desktop applications, and Defold is no exception.
In short, he goal is to run as fast as possible, to have as smooth framerate as possible.
E.g. disabling vsync, is one way to make it run as fast as possible.
Try removing that variable (it’s deprecated, it’s equal to swap_interval = 0) to see if the project will ease up on the cpu usage.
