Ah ok i was typing and didn't saw your post. Understand. How you can see the diff is maybe not with a performance boost but visual input lag. I usually pull the steering wheel fastly left and right and it reduced the lag for me, as the overall performance is great with my settings on my machine. as well. I do realize that everything under. 90+ fps leads to a stutter fest in rf2 or at least isn't as fluid as with greater fps. I also do feel the diff while driving with or without the reg entry. What i can't say is wether the value has a different effect on diff hardware. Maybe you should try diff values.
