When I was testing with my new 120hz laptop display and a DLL injector that unlocks the frame cap, I noticed that Motor6Ds in an upcoming game go a lot faster than they should. The video above shows a green part with a BodyAngularVelocity (expected result) and a red part with a Motor6D. The speed of the red part decreases when the frame rate decreases, and increases when I unlock the frame rate.
