I'm interested to know how the netcode works, playing in burger servers (~100/120ms) I had absolutely zero issue shooting, moving and rocket jumping.
It could mean that it's entirely client predicted (moving and rocket jumping isn't delayed) and heavily lag compensated (favor the shooter), the former is great, the latter is mostly fine until you get railed behind a corner or rocketed without seeing it being shot.
It's also possible they're blending in server-side extrapolation just like Reflex did, maybe with a different or no upper bound (Reflex has 80ms). If that's the case, then awesome.
