During E3, AMD released a new graphics driver, 17.6.2. It doesn’t list any general improvements, and just a single fixed issue: improved performance on DiRT 4 with 8xMSAA with the most recent game build. If you play this game, then you should consider updating your graphics driver.
If you aren't intending to play DiRT 4, and you're already on 17.6.1, then you could probably skip it. That said, if you have an issue, and it’s not listed in the Known Issues section, because those definitely aren’t fixed yet, then you can give it a try.
