Thorsten, this is just amazing!
One question I need to ask:
What is the recording frequency? Can it be adjusted by the user?
cheers

> avoids copying data around. It'll also use less memory, since most

> tank/gear/engine/propeller properties. On the other hand, most jet
> engine properties weren't recorded so far - this will also improve. And
> the obvious advantage of the new system is the option of recording
> custom properties.

> Finally, the new system also comes with a new replay "dialog". Looks
> more like a video player, provides a "time slider" and, also new,
> introduces slow-motion play back. Sneak preview:
