I mention that mostly couse from the passed time and all little bugs it had with Magna Carta I wouldn't really use it to increase playing quality as fps increase isn't all soo important when the game works as desired, but it for sure is a good way for desperates with very old/weak hardware as anything is better than slow motion and this really was better than built-in pcsx2 frame skipping. Soo yeah like in that example you can use this adress in both ways, the other meaning decreasing requirements(for both cpu/gpu) by accurate frameskipping.
Just an example of same thing forgotten in time. I bet this would work with other games too that you have control of their ingame speed.
