Hey there Mac Community,

For those who don't remember this issue, USB headset on Macs with a GeForce 9400 can cause performance issues.

If you are using a GeForce 9400 and a USB headset, basically combining the 2 will result into a drastic drop in performance in all OpenGL applications. This is a hardware bug with Mac OS X. Non-USB headsets are fine.

MacBook Pro owners with a GeForce 9400M and 9600M GT, please make sure that you are using the GeForce 9600M GT. You can do this by going into System Preferences/Energy Saver and choosing "Better Performance". Non-Macbook Pro can unplug the USB headset to restore any post performance due to the hardware bug.
