I still see unnecessary keyframes
After a second look - "Too many vertices in one geoset: 9203" - this will cause glitches in-game. Split the geoset or reduce overall vertex and poly count.
Why the model has 21000 polygons thats way too much. Polycount isprerefeable to be reduced.
Also why you have so many collisition shapes? 2-3 at best should be enough. The collision shapes are not positioned correctly.
Change the format of the used texture from DDS to BLP to be compatible with older patches
overhead Ref is positioned too low
