Nope (still downloading because I dont let my laptop all the day on), but it's 6.5 GB so I presumed it was pretty good.
Moreover the file format is .mkv, so I guess the encoding is H.264 (mkv's are often in H.264 and it's the most efficient encoding yet).
On the torrent page it's said that it's 7 hours long (so I think there are also on-the-fly rendered cutscenes, and not only
full motion videos).
We have 7 hours and 6.5 GB, which gives a divx like time/weight ratio,
BUT in mkv (and H.264), there are HD movies (720p) encoded in ~1GB.
So approximately 1h30' for 1GB => the ratio is 1.5 hours per giga
With this ratio, 6.5 Go would give us 9.75 hours of HD video; and we have here 7.
In conclusion, I would say that
the quality is almost surely of 720p, but it's just assumptions
