To me, (Asus Maximus Formula), the latest intel driver that works is 10.8.
I've tried >=11.2 but none of them work. It seems that the driver doesn't support ICH9R as it's not listed (you can check trying to force the driver installation and the list skips 9R; even worst, some drivers has 9 mobile support, but not 9R).
It's a shame for a company like Intel to have this kind of support. Next time it'll be AMD for me. It's not the same level of performance, but better price/performance AND better support.
