That's not how latency or responsiveness works.

Dan Luu did cool experiments with input lag (https://danluu.com/input-lag/).

It's a much better estimate than hand waving about memory isolation.

If we want to talk about how things work directly, my program can get things to the GPU in far less than a millisecond. The safety layers are not the problem.
