Late last week, Valve Software alerted users of its Steam game distribution platform that Apple's Mac OS X 10.6.4 released last Tuesday appears to be causing performance issues for players of high-end games on Macs with NVIDIA graphics cards. As a result, Valve recommends that users for whom this might be an issue hold off from updating their systems.
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.
Valve made a splash earlier this year when it brought its popular Steam platform to Mac OS X and began releasing titles in its own game library for the Mac. While Mac users of Steam have reportedly been enjoying relatively good stability compared to Windows users, they have also been experiencing lower framerates, degrading the gaming experience somewhat.
We noted last week that Valve is working with Apple, as well as graphics card manufacturers NVIDIA and ATI, to improve drivers and make other changes that should improve the gaming experience on the Mac platform. In the meantime, however, Mac OS X 10.6.4 appears to be a step backward, at least for high-performance games, and it is unknown when Apple will address the issue.
