Ping/Velocity Interpolate

In the debug menu there is an option for Ping Interpolate, and for Velocity Interpolate.

Can someone explain what they do?

In particular, because I use satellite internet, my ping times tend to be around 1500ms. Bandwidth is high, but latency is poor due to the long distances.

So, I am wondering if some combination of interpolation methods might be better or worse for me.

Turning velocity interpolation off tends to make things more jerky than having it on.

Turning it off will also break llTargetOmega rotating prims.

Damn.. 1500ms pings? To use an interactive online game, I found it was like treacle when ping timmings went over 300.... .

SL is not a game, it is a place.


Yes, it is tricky. I avoid anything fast twitch.

Turning that off also tends to stop "rubber-banding". Instead of sliding along and then bouncing back, you see things simply freeze in place and resume once the lag/network spike is done. It actually comes in handy for me, since I do a lot of melee combat in-world and would rather know where my opponent *really* is, even at the cost of the experience being a little more jerky in appearance.

Based on my experience with using SL with velocity interpolation turned off for most of a year now, it appears to me that Velocity Interpolation just makes the client keep rendering an object on it's last trajectory and velocity between the more authoritative updates from the server.

And yes, turning it off breaks all appearance of llTargetOmega making things rotate

.

So, does anyone know what Ping Interpolate does?

What happens if you have both, or Ping but not Velocity? I have experimented, but cannot really see any difference.
