[TF2] Walking/standing on moving objects causing view jitter #4186

Open Thespikedballofdoom opened 2 years ago

Thespikedballofdoom commented 2 years ago

It's not an FPS or lag issue, it is tied directly to the game and scales with host_timescale too. I started noticing this after upgrading from an intel i5 and rx 580 to a Ryzen 7 5800X and RTX 3070. It wasn't caused recently, as I tried this out on the pre-JI demos beta and it was bugged there too. Tried changing cl_smooth and even setting cl_smoothtime to 2 but this still happened even on those settings.

To reproduce this, just get on any entity like a payload cart that moves and walk on it while it's moving.

Can confirm with my GTX 650 Ti Boost and my Intel Core i5-3470 CPU

This happens because cl_interp/cl_interp_ratio being lowered either by the user or the server enforcing a lower interp value (my definition of "lowering" equals to lowering a value)

This is the same reason why the skeletons minions stutter in Halloween. (and changing to stock cl_interp/ratio value and stock cl_updaterate/cl_cmdrate value just to have a smooth cart and smooth skeletons, is something that nobody would like to do anyways)
