Game runs well on my system (i7 930, 24gb RAM, Geforce 480 SLI). There are no Video options beside the resolution & vsync. In-game textures were blurry but I forced AF and FXAA in the control panel and everything looks sharper now. As for the game itself, took me about 30 hours to beat while doing most of the side quest. There is basically no story to this game, more like an after thought and *SPOILER* the ending is terrible. This plays the same as its predecessor, hack and slash but has loot drops now.
Played the game using a 360 controller and controls were smooth. I didn't try keyboard/mouse setup so your mileage my vary with such options on these console ports. My opinion, wait until it drops to the $20-30 range. You are also not missing much in terms of the pre-order weapons/armor bonuses. They are great in earlier levels but once you've progressed, the in-game loot drops are superior.
