I expected latest updates to correct a bit of it, waiting with hope, but still not...
Even with the ED planes from genuine DCS (no mod at all) with the latest updates, I get so many changes in replay, I never could get even one video of the key instants of an interesting fight.
As far as I understand it from replay viewing (even more obvious when comparing tacview files of fight and its replay) the track files store some controls but not position-attitude and events (impacts, damages), relying on AI and physical computing to estimate intermediate replayed position. Theoretically, it would work in a realtime engine, but it's not one.
Since tacview gets position data from DCS engine, I suppose these could also be saved in replay... strange.
Yet, while not storing all position-attitudes in the replay, maybe some key steps (used like i-frames in compressed video streams) would correct unexpected changes and would allow extracting more of the interesting parts of the track than the current replay tool does, stacking errors on errors.
I long for the replay update.
