QTimer isn’t reliable #16
Description
When a QTimer is used for timing frames, either in the viewports or the demo player prototype, frames can lag
The error / deviation accumulates too.
We could look at the time taken to execute functions tied to the timer and compensate for the deviation
Or asynchronously run the functions with a 1 frame delay, showing the previous frame (double buffering) some kind of “delayed execution” QTimer subclass (GFrameTimer?) could be useful
