I downloaded the beta, set resolution at 1440x900, balanced settings, and I got a very great framerate. Great to me is 30+ fps and I was average about 35.. the most being 45, least being 25. My specs are in my sig. Note that I have 177.92 drivers and OC'd to 575/630 using nTune. I did everything from quests to PVP. Playing RVR was actually very fun and framerates never dropped below 25fps if it ever dropped below 30fps.. which is very doable and playable. When the full release comes out, I'm pretty sure there will be more options to change settings. But I just wanted to let this community know because I've seen a lot of questions about Warhammer Online on Macs.
