The new ones didn't seem to receive much fanfare compared to 45.23 and past drivers.
What's a WDM driver, and why does 45.33 get the unusual tag of Graphics Driver on the list (the other don't carry tags)? And why are the 52.16 drivers dubbed Forceware? It wasn't until yesterday that I realised these sets existed.
