SMC Update 1.1 Macbook Pro Retina 15" with Bootcamp Win 7 FPS in Games

Question

I have the 15" Retina Macbook Pro, and I have definitely had issues with framerate in games played on bootcamp windows 7. The game I am testing fps is Rift. I noticed when plugged in, the fps drops significantly compared to when it is not plugged in (on battery.) Running on ultra video settings at 1920 x 1080, when plugged in I am getting between 7 to 15 fps after about 3 minutes of sustained use. When unplugged however I get a sustained 34+ fps.
I installed the two new updates ( OSx 10.8.3 and MBPr SMC Update 1.1 ) in the hopes they would resolve my issue. However I am seeing the same fps problems as before.
Additionally while running the game the fan spins like crazy at all times and the power cord gets quite warm. Upon quitting the game, the fan continues to spin wildly with no end.
Can anyone else reproduce these observations? I had an open ticket with Apple to fix this prior to the update on my machine. I was so excited when I saw the release notes to these two updates as it appeared they would directly address my problems. Unfortunately there has been no significant change. Needless to say, my work order shall remain open...

Hi All,
I tried this and it improved my FPS in games yesterday, still not getting FPS I would desire, but its become playable.
Repasted here from another thread:
My retina MacBook Pro has had terrible graphics performance problems for a couple of weeks. I searched all over various forums and tried everything: resetting SCM, manually selecting discrete/integrated graphics card, deleting graphics kexts, etc. Nothing helped until I found this: https://discussions.apple.com/message/19880198#19880198
Now my rMBP has silky smooth graphics again!
The directions in that post are a little hard to understand so I cleaned them up here:
Step 1: Delete system windowserver preferences
In the Finder, from the menu bar, select "Go -> Go to Folder..."
Enter: /Library/Preferences/
Delete the file called com.apple.windowserver.plist
Step 2: Delete user windowserver preferences
In the Finder, from the menu bar, select "Go -> Go to Folder..."
Enter: ~/Library/Preferences/ByHost/
Delete all files that start with com.apple.windowserver   (On my rMBP, there was one file called com.apple.windowserver.12AFB147-95D6-5C70-8F62-C1E4F2BE81BE)
Step 3: Reset the PRAM    (These instructions are from http://support.apple.com/kb/HT1379)
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Hopefully this helps others with bad graphics performance on retina MacBook Pros.
For anyone that wants to check out the problematic plists from my rMBP, here are the files:
