That does not sound like a frame rate issue but as a input lag issue. |
It was per illustration of why I think a steady frame rate is essential. If the slight difference in input lag between tvs already makes a difference, then dropping frames or variable frame rate would be just as bad for precision. With a locked frame rate you can expect to move exactly 1 meter forward each frame at 216kph (60 m/s). That steadiness makes it possible to fine tune brake and turn in points to the cm. But if say you have VRR going between 40 and 80 fps, now each frame you move between 1.5m and 75cm forward. Or when dropping to 30fps (dropping a frame) now the next frame you make a 2 meter jump, while the last 1 meter jump appeared 17ms too late.
30fps racing works fine too as long as input lag is kept low and zero judder. 30fps gets problematic when the frame time is sometimes 17ms, mostly 33ms and sometimes 50ms. (Delivering 30fps on average). Higher frame rates decreases judder (as well as VRR) but the real problem is needing a steady locked fps.
