A frame-limiter and fixed-timestep are not the same thing.
Now that makes sense. This was the comprehension that I was missing.
That said, I’m not sure how best to implement a frame-limiter in Monogame. As illustrated in my earlier posts, I would like to have some sort of Sleep between updates, but the Tick method is not accessible in subclasses. @Jjagg, would it be beneficial to mark it as protected in the Game class to allow such alterations?
