Are Nuts&Bolts and Perfect Dark Zero working now?

Has anyone gotten to try these games since BC officially launched? The frame rate was awful when I tried them through Rare Replay.

I've been playing Perfect Dark Zero since summer on X1, through Rare Replay and the performance has been fantastic.

Just tried Nuts and Bolts, it's still the same :( framerate can get all sorts of messed up from time to time

PDZ plays great, Nuts and Bolts still not so much.
