There seems to be a small drop in some areas with the new driver, but most the time there's either no change with overall performance or a nice little bump which is always appreciated across the resolution board in a couple of games.
Outside of the performance, though, there are some seriously awesome improvements to this driver set when it comes to the feature set, especially when it comes to CrossFire improvements. In saying that, if you don't make use of the technology this driver is still a fantastic one that offers a nice performance boost in cards starting as low as the HD 5770 from our testing.
As always, there's a nice array of bug fixes that have come to the party which is no doubt going to be appreciated by a number of people as well.
The good news is that not only is this a great driver, but we know that next month's is also going to be fantastic with a number of new features that we saw in our preview Future ATI Catalyst Drivers - Why you should be excited!
There's really no reason not to upgrade to this driver if you're using an ATI based graphics card, especially if you're on a HD 5500 or HD 5400 series card with this being the first official driver for the model.
Until next month, may all your frame rates be high and your games good fun!
