As far as I can tell, this method removes the standard additional 0.1s interpolation between positions, so the gain is a maximum of 0.1s. You also showed some results, but I don’t think they’re a good representation, as a simulation inside of Roblox Studio is far different from a real game with players that have a far more unreliable connection. There’ll be many more visual glitches than normal, so I doubt that this module is worth implementing, unless I see evidence that proves otherwise.
Yep, I have had these reports coming from multiple people. Which is interesting as my own R6 ragdoll system does not break (even though I use the same source code as the others). Will have to do a deeper dive once I find the time for it
