Just had a quick go on the Beta. Gotta say, it ran like crap. Didn't look too great either. Though the skyscraper had already been taken down when I joined. So all the dust might've made things worse. I also remember the bf3 beta didn't have the highest settings enabled, even though you could select ultra. Maybe the same case here. Anyway, just noticed amd put out 13.10 Beta 2 drivers yesterday. Gonna try them out and will let you guys know how I get on in a bit..
