30fps is normally alright for 3rd person adventure games, but shooting, especially first person, might feel different. Idk, I still don't know how to feel about this one. The digital foundry guys seemed to be supportive, but I still just don't trust Bethesda lately
Personally, frame rate is much more important to me than most other factors. If there's the option to, I'm going to be cutting a lot to get it to 60, especially since I'm somehow way below specs with a 6600 xt
