I've seen various questions about this issue, but no conclusive answers that work for my case, which is about as simple as it's possible to get. I find it difficult to believe that this is an actual issue that cannot be solved, it's so fundamental to 2D games.
If I move a sprite in code in the
_process(delta) function, using the delta to control speed, the result is unacceptably "stuttery" or "jerky". I've created as simple an example as I'm able to here, https://github.com/pgregory/godot3_tests/tree/master/stutter, which is simply a sprite, being moved across the screen.
If you run that, you'll see that rather than a smooth continuous movement, it stutters at irregular intervals.
This is currently a showstopper for a 2D game I'm working on, so any advice very gratefully received.
