With the 5.32 you can see performance drops in tests with FSAA enabled. With the 5.32 there is a consistent 300-400 point drop in the results from the 5.30. This could mean that it is now in working order. As the high numbers from 5.30 led us to believe that it was being auto-disabled.
All these results are considerably better than the 5.22 officials. How stable these drivers are is up for debate though. We have heard of people saying they don't work well with Diablo 2 or other games. These problems could be system specific or global, you won't know until you try.
We see enormous gains when looking at FSAA values, in some places almost doubling performance. We also have to take these numbers with a grain of salt though. Notice that the 4x numbers don't drop very much when changing bit depths at the high resolution. We believe that FSAA is automatically being turned off when the workload becomes too strenuous for the card.
