Hey @Ateria! The rubberband-ish movement in the video is probably due to frame-rate drops due to my recording software (OBS Studio) eating a lot of frame-rate. Without OBS Studio running, the game seems to run smooth. There are occasional prediction errors in position/rotation, especially with time and lag spikes. Usually, the position/rotation error is under 1e-6 Babylon units.
I haven’t developed with nengi before, though I’ve played zombieswithguns.io made with nengi, and the gameplay is really smooth.
If you posted a question about your experience with prediction errors, we could help out!
