I have a VAIO PCG-K415B (with a Radeon IGP345M integrated graphics) and I'm aware that the ordinary ATI driver updates aren't compatible with it. Is there any way to get updated drivers (either from Sony or somewhere else) for it?
If there are any Sony updates then they will be at Vaio Link - it's unlikely that there will be any newish ones though.
You could try Omegadrivers for unsupported drivers.
