timescale causes choppiness

[Remixful]

Altering timescale will cause choppiness in movement and looking. Setting it to something low like 0.3 will cause connection problems (even on lan)

Update: This only occurs when connecting to local server

Okay, connected to a server with timescale 0.3 and then when walking, at some interval, the movement skips forward in time. As a guess it might be transitioning to the next server gamestate snapshot too soon or something.

This issue also occurs using ioquake3.

Just for the record: maybe check this -> tendaikon/ioq3sim@a2572df to fix the timescale issue, idk.
@zturtleman I'm too low skilled with engine stuff, but the ioq3 fork I pointed to above looks interesting maybe (residual memory, enhanced performance, etc.).
