I can pretty much confirm that the game is basically unplayable with everything turned on on DX11 rendered, meaning Very High details, diffusion depth of field, ambient occlusion and 8x AA, 16x AF, 1920x1080 resolution, vsync off (and just to be clear, I'm talking about the retail version, NOT the demo) with the high quality texture pack installed.
Specs :
i7 920 o/ced @ 3.5 Ghz
MSI GTX 570 (single card)
6 GB RAM @ 1600 Mhz Tri Channel
Windows 7 Ultimate 64bit (fresh install) with 264.24 Nvidia drivers.
I'm currently running around in Kirkwall trying out different settings, in order to find something that will work optimally work for me. Here's my observations :
Anti aliasing plays a HUGE role in terms of fps. Even 2x can have a significant performance hit on your gameplay. AF doesn't seem to affect fps much. Other than that, going from High graphics detail, to very high also incurs a serious performance penalty. Ambient occlusion had as much as a 50 fps hit ! (jesus). Right now, I've settled for high details and no AA, until either Bioware improves performance via a patch, or the new drivers (tomorrow ?) help to alleviate the issues.
Edit : Settled for DX11, High, ambient ocllusion on, 16xAF, No AA and high quality textures. This brings me around 60 fps according to Fraps. With very high, this goes to 30 and I don't feel really comfortable.
