Been playing this, somehow much easier to get into than Oblivion, I really like it.
Game used to crash every 10-15 mins, changed to 44.1 khz and 16 bit, and game is rock solid, have had sessions of 4 hrs and no problems at all.
Stupid developers, didn't they learn from the Fallout games not to **** up game stability with audio crap ?
Amazing imho how much interesting stuff, and details there are in such a large world for only a 6gb game. World also feels far more alive than Oblivion ( I somehow hated that but love this)
Only thing I have issues with is the whole weapon and spell system, I'm always messing about to get the weapon/shield/spell combo I want. Favourites system is still rubbish imho. Always spending more time than needed picking my weapon combo. I want 1 to be my bow, 2 to be my sword and shield, and 3-9 other stuff, but when I press 2, sometimes I get Sword + magic/spell instead of sword + shield

.
Aside from that, I'm surprised it runs so great, 1920x1080, 4x MSAA, 16x AF, FXAA, everything else maxed/ultra. Not noticed 1 stutter, yeah the framerate sometimes does get a bit low ( about 25-30's, I believe, not checked the actual frame counter but teh framerate is lowered a bit sometimes), but for a slow RPG like this it doesn't matter, I'm surprised I've not had even 1 stutter unlike in Fallout games ( Atm on i7 @ 3.4 ghz, 12gb trichan 2000mhz ram, GTX570 and game & OS running from an SSD) even if turning around like an idiot or messing about.
