AA should be enabled. I can't read Korean though. We're better off waiting for the English version to make sure everything is enabled.
Really though, you can't justify the breathtaking graphics in Aion with screenshots or videos.
. Also I will attempt to enable AA via the Nvidia control panel next time.
Edit: Actually, I think it was my modified driver. I'll install the latest instead.
Edit2: Ok with the latest Nvidia driver and me having the Nvidia control panel set to quality, Aion now look even sexier. Nice.
