> that does not change that it is not related to GPUs or the graphics stack itself. Working in the Linux display server space makes me quite comfortable in my understanding of GPU's display controllers.

I didn't mean to suggest some sort of fundamental limitation in GPUs that makes it impossible to synchronize this. If you take a look at my previous comments, you'll see me explicitly pointing out that I'm talking about Windows, specifically, and I'm only using it as an example of how short a latency is still perceptible. How exactly that latency happens is almost certainly not a hardware issue, however, and I never meant to imply such.
