Just tried this. Got really excited when it went from launch to empty server list in fifteen seconds instead of over a minute.... but that was only first launch. I've had precisely zero successful logins since 7.0, unless you count the one using a borrowed older machine...
I'm using the website-downloaded client, not Steam. I don't want to install again. I wish they'd tell us what the issue is... I'm very curious. This, along with other issues, has turned me off to buying another AMD-powered ASUS laptop ever again.
