Recent, clean install of FS2, loaded up with nightly: http://www.hard-light.net/forums/index.php?topic=86779.0
and MV_Root.VP only (don't ask why).
Training mission 2: Rate of fire borked (high) and varies throughout the mission. Proof:
Pretty sure the Subach isn't that peppy.
Then again, it might have been the game speed that was broken. Flying around the station in that mission felt fast.
No debug log because none appeared in my fs2 directory yet. Perhaps because it's not a debug build/not actually a crash. Midrange AMD gaming pc (955 BE, HD5850, 8GB ram)
Sorry for the unhelpful description/if someone else already reported this.
