When I install AMD Driver 15.7 for R9 275x. While installing the driver version is shown as 15.200.1046.0 not 15.7. So where driver version 15.7? Background information of my computer,
Windows 8.1 64bit
The reason why I am trying to install the new version is that when I run Battlefield 3. It does switch to amd gpu. However, game runs.
