Hello, I’m Using 4.17.2 and still have the same issue. I’ve experienced that issue back to 4.15 and could fix it by magically just checking/unchecking the “smooth Frame Rate” box. Although that wouldn’t work each time.
Now I’m using 4.17.2, that “trick” doesn’t work anymore, the frame rate is still locked at around 120 fps, and if I check the “Use Fixed Frame Rate” box, I can have my desired frame rate (Which is 90fps as I’m working in VR).
However, I almost have the same issue as @lennysunreal have mentioned before (Mar 28’17), My physics is completely messed up, but not like @lennysunreal, it hasn’t been speed up but slowed down, like everything was underwater.
Another Oddness, this happens only when the physics is played under a certain height (around 50~ 60 cm).
I hope my report helps to find out what happens, because it’s already been a long time that this issue has stuck around.
Max.
