0003317: Gametic-based unlagged does not respect cl_ticsperupdate
Quote from Watermelon
- Takes into account cl_ticsperupdate
The user can change their ticsperupdate at any time and it will work just as it should. This is due to it being bundled with the movelocalplayer command, the client gets the server gametic as needed.

Turns out this is not true.
Using the test wad and the debug commit referenced in 0002859:0018627:
-host a server on MAP01 with sv_unlagged_debugactors true
-connect and join 2 clients
-turn cl_capfps on (this will make it much easier to see what's going on)
-change cl_ticsperupdate to 2 or 3
-notice the gametic debug actor rapidly jitters
-you may also try to hit (provided 0003316 is fixed at the time) and you will find that hitting your target is very difficult
This is because the clients re-send the same server tic 2 or 3 times (depanding on the setting) since they receive no updates in the meantime.
No tags attached.

I tested with r200329-1854 and had both clients running 3 ticsperupdate. The linked gif is my result. [^]

Seems the red debug actor still jitters.
