There’s a lot to bitch about!

To each their own, of course, if you prefer not to use the features. But it’s not actually simulating any gameplay, it’s just interpolating new frame data from already-rendered frames. The actual game logic isn’t being simulated or affected at all. You can think of it as just smoothing out the end result, which has already been computed by the game engine.

That being said, I’m not sure how it would impact a game that has incorrectly tied its game logic directly to the framerate. My guess is the interpolation step still happens after all that occurs, which means it would still not affect actual gameplay, but someone who knows more can correct me if I’m wrong.
