Something. Continuing my comment on the previous beta drivers, after using them for some time, it seemed to me they are a tiny bit slower. I didn't do any measurements, so this is highly subjective. No errors though, and they had cured one gripe I have always had with this chipset (eventd error: iastor did not respond within the timeout period); no hardware is defective and I've seen that error on many other computers; but I'm trying these ones (so far so good; plus they're signed).
