Here's some notes on what Windows Experience Index reported through the process as I updated my new EP121 tonight- 1. WEI 3.1 - default system right out of the box (limited by graphics score) 2. WEI 3.3 - SP1 and all windows updates EXCEPT new Intel graphics driver installed. Intel HD Graphics Driver version unknown. 3. WEI 3.1 - new Intel HD Graphics Driver 184.108.40.2062 (?) installed through windows update So I'm guessing that the latest graphics driver from Windows Update may be sub-optimal for the EP121. Can anyone confirm this? I've seen WEI fluxuate .1 in tests but never .3 Update: Oh, I see that 220.127.116.111 is the latest at Intel at the moment. I'll try that and update this thread asap. Update2: WEI 3.1 running the latest Intel 18.104.22.1681 driver.
