XaveT :
It looks like one thing is still quite the same between the two: You don't have the option to install the driver and not the "driver and software". You also always get the "install manager".
Is it a pipe dream to want to not have to hack apart the installer to just get the drivers?
Have not tested this version, but with all Catalyst drivers before, when you run the installer, it extracts to a folder, then close out the installer. Inside this folder in a subfolder there is just the driver folder. In Windows device manager, you can select update driver and point to the extracted folder, default of c:\amd and it will install just the driver, and nothing else. But you don't have access to advanced features to control without the software.
