Apple BootCamp supplies users with correct Windows drivers and configurations to let them use Apple Hardware with Microsoft Windows operating system. Sadly, these BootCamp drivers are not updated at par with their OEM Windows counterparts and trying to update these using OEM version does not work. Updating drivers gets specially compulsory in-case of bundled graphics cards (usually AMD Radeon) as newer games complain about outdated drivers which create compatibility and performance issues for them with the error shown below.
"Detected AMD Radeon driver version 11.1. The recommended driver version is 11.7. Please update drivers at http://www.amd.com/ before playing this game."
