Apple has released NVIDIA graphics update that addresses issues with Mini DisplayPort to Dual-Link DVI adapter and also improves HD performance on Mac notebooks using NVIDIA’s GeForce 9400M chipsets and Mac desktop using NVIDIA’s graphics chips. The update is available via Software Update feature on Mac and it is 3.2MB in size.
Apple in the release note says the update improves cursor movement when using Apple Mini DisplayPort to Dual-Link DVI adaptor for Mac Laptops and HD video playback. Apple provided no other details.
So we decided to test the update ourselves. We used Xbench to test before and after difference in performance on 2.0GHz MacBook (Unibody). We looked for improvements in Quartz Graphics, OpenGL Graphics and User Interface tests. There was only slight improvement in Quartz Graphics test from 154.68 to 159.68 points, whereas OpenGL test saw a decrease in score from 138.59 to 134.50. But it was the User Interface Test that improved by 6.6 percent from 226.27 to 241.01.  So Apple has definitely improved User Interface performance like cursor movement and page scrolling with this update, go ahead and download it to see the difference.
