Got a laptop with AMD discrete graphics, and Intel integrated for saving battery? Vendor isn't providing updated drivers? AMD shrugging and pointing in another direction? Thank goodness for third party drivers.
Quite often, after a laptop release, the thing is just forgotten about and drivers are left to languish. Despite AMD offering Mobility Radeon drivers, more often than not, they won't work, with AMD pointing people back to the vendor who stopped caring the moment you bought the laptop, as they apparently implemented a custom solution. Thus, games and other applications can have issues that never get fixed.
Thankfully, if you're running Windows 7 x64, we have Leshcat's drivers.
While the usual caveats apply about not using vendor authorised drivers, install at your own risk and so forth, but these may just get you out of a pickle.
