Impact with 5000 series doesn't seem to work - LN2 mode off = high CB, LN2 mode on = 92 every time you try to set anything in BIOS (even vcore!). This is on latest BIOS.
Score averaging in the 4K stage is screwed, e.g. USA has a full set of subs averaging out to about 7 FPS but the stage shows 1.08 fps (I can't believe I'm helping mortal enemies ?)
