I've figured out how to recreate the low frame rate problem on my MBPR.

Steps:
1) Connect the power adapter to the MBPR. Make sure the light on the connector is turned on.

2) Reset SMC to clear the problem. Press the Shift-Control-Option keys (on left side of built-in keyboard) and the power button at the same time.

3) Turn on the MBPR.

4) Run game and login. The frame rates should be normal. Make a note of the FPS. Notice how the fans spin up loudly.

5) Put the MBPR to sleep by closing the lid.

6) Disconnect the power adapter.

7) Wake up the MBPR by opening the lid. I left it awake for about 10 seconds.

8) Put the MBPR to sleep again by closing the lid.

9) Connect the power adapter. Again, make sure the light on the connector is turned on.

10) Wake up the MBPR by opening the lid.

11) Run game and login. The FPS will now be about 1/3 of normal. Also notice how the fans barely spin up.

If you command-tab out of game, the entire Mac feels laggy. Menu bars drop down more slowly than normal. Dragging and resizing windows in other applications also suffer. As soon as I quit the game the Mac feels normal. The game will continue to have the FPS problem until I reset the SMC again.

The usage pattern that I've described above is one that I do all the time. At my house, I use the MBPR while connected to a thunderbolt display which provides power. I sleep the MBPR, disconnect it from the thunderbolt display, and take it out of my house. I use it away from my house on battery power. When I'm done I put it to sleep then go home. After I get home, I reconnect the MBPR to the thunderbolt display while it's still sleeping. I then wake it up using an external touch pad. I go to play the game and get terrible frame rates. I reset the SMC and all is well. Until I repeat the pattern again the next day.

I'm pretty sure this started after I applied the 10.8.2 and firmware updates.
