Predictions are on. Also I think this may not be entirely attributable to ASW. I found in one of my old vids that the stuttering in vehicles wasn't present in my early vids, the hl2 buggy worked before, I guess I must have broken something somewhere. I wonder what though... The template SDK for alien swarm by Doplhur seems to have the same problem, the jeep is doing the same thing.
I printed the velocity of the client and server to the hud, and they're identical, cl_pclass isn't reporting the velocity correctly for some reasons... Also here's the full code, some of it is from Eternal Silence, its pretty messy though. : http://pastebin.com/eMcKh1YL I used a CPhysicsPropMultiplayer as the base prop, because the other prop types made even weirder stuff.
