Upon further review, however, Concentrated fire seems to be working, and not the others. Sorry for that. Is this patch worth the trouble to get, since my level 20 wasteland monster is killing Deathclaws and enclave soldiers in his sleep?
Sorry...
*EDIT* S'pose I shoulda read the post...
Concentrated fire uses a different http://geck.gamesas.com/index.php/Entry_Point than Gunslinger/Commando/et al (which is Calculate To Hit Chance). That's why it still works.
For your maxed character, probably not. But if you were to start a new character, you'd have the messed up VATS to deal with.
It's more than just the perks, there's a noticeable pause in activating VATS. I've noticed two kinds of VATS loading pauses: There's one where the screen gets stuck momentarily in some super-fuzzy deal (it occasionally completely borks up all my AA settings, so I think it may be video card related), and then another where you see a jaggie-infested thin green outline around your target before it suddenly turns into the usual green aura around the body part being moused over (which I think may be some sort of visual silhouette check for visibility calculations). All versions may suffer the AA pause, but only those beset by the VATS bugs introduced by v1.1 will have the "Calculation pause". You see the jaggie-infested green line for a split-second in the un-bugged VATS, but sometimes for 2 or even three seconds with the bugged VATS.
And then there's the calculation errors and 0% chance to hit grenades and rockets.
