Continued from 0003418: (3.1 alpha) Stuttering ingame

There's currently some bugs fixed and readjustments being made to Zandronum's unlagged system, which required changing some time functions and make them similar to GZDoom. There was some stuttering caused by a bug which was fixed later, however, after the fix and the change in code to make the timer the same as in GZDoom, it broke the turn180 command and made it stutter compared to before. As reported by the user below, the command causes the view to jitter compared to before when using the command.

To prove that the suttering is not completely gone, i had to do this:
In console, bind "Turn180" to any key
Spam such key and you will notice your screen suttering.
(This doesnt happen in 3.0 and lower versions of zandronum)
Edit1: The suttering is even worse if you try to move while spamming turn180

It seems that it has been broken since forever in (G)ZDoom and earlier compared to Skulltag/Zandronum. It's very easy to see the difference between Zandronum 3.0 and GZDoom when using the command side by side. In Zandronum 3.0 the view remains completely smooth whereas in GZDoom it looks like it's locked to 35 fps while using the command.

There's no interpolation.

Could this be replaced with A_SetAngle?

Shouldn't any bind that touches the player angle trigger the interpolation anyways? (LocalKeyboardTurner variable I think)
