Poor Steam Performance Under 10.6.4 w/ nvidia GPUs

Valve Software has documented a known issue that causes severe performance degridation for 10.6.4 users with nvidia GPUs. Valve Software is advising that users avoid updating to 10.6.4 to avoid experiencing this issue. Unfortunately many of us patched before becoming aware of this issue. The performance hit has been very drastic between 10.6.3 and 10.6.3 and sometimes makes games unplayable.

Valve states this is an issue with 10.6.4 and not with Steam:

+The recent 10.6.4 update from Apple has noticeable performance issues for NVidia graphic chip owners running high performance games.+

+If you wish to avoid this, you should consider waiting to install the 10.6.4 update until Apple has had the opportunity to address this issue.+

+Full details of what is contained in the 10.6.4 update can be found here: http://support.apple.com/kb/HT4150.+

+If you have already installed this update and believe your graphic performance is affected, please contact Apple support ( http://www.apple.com/support/) for details on what to do.+

Half Life 2 is completely broken for me in 10.6.4. After the update, large parts of the screen simply do not display. Walls are invisible, texture mappings flip into strange patterns, and the game freezes randomly. Half the time it kills my entire system and I have to do a forced reboot. The game is completely unplayable. I actually WISH that I was simply dealing with huccups, lags, stutters and reduced frame rate. The screen shot I took of the last attempt to play is just awful - it looks like someone threw my display into a blender.
