|First off, that is an interesting article, and if it is correct, I stand corrected that your graphics engine does effect how far your jump.|
However, please notice that your jumping distance is apparently erratic.
At fps of 145, you have this value that adds to your jumping distance: 46.83. @ 161, it's 3.35.
It would seem to me that you would probably want more consistency in your jumps, not expecting to jump far only to happen to get a few more or a few less frames that causes your jumping to be reduced. If that's the case, VSync capping your frames would ensure your fps would be a consistant number if your system can render at or higher than that speed.
I'd also like to point out that most people aren't very particular about being able to jump a little bit farther, but they do notice image tearing.
