yea but how bad does it look and run? also do you use mods? i've heard mods need more ram to run smooth
I think it looks a bit worse than it does on the 360. I also had to try different settings to make it look ok without causing the game to lag too badly. The settings I now use are medium texture quality, medium shadow detail, low radial blurr quality and antialiasing is set to 4 samples. I also fiddled with the display settings ingame to ensure that people and items don't seem to pop into existance when I'm a mere 4 feet away from them.
I use a lot of mods (30 or so are activated at the moment) but so far, none have given me any trouble. Some of the mods I use are Cloaks of Skyrim, better dynamic snow, better static meshes, various armour and weapon mods, the dragon falls manor, horse armour, follower overhaul, UNP body, new hairstyles and eyes - you get the picture.
One thing I will say though, is that my graphics card seems to have a lot of difficulty with spell and lighting effects. It doesn't lag, I simply can't see some things. Frostbite for example. The frost effect itself is visible, but the blueish jet of light is not. The lights in the Mzulft Oculory are another good example, they were so pale that I didn't even notice them at first. They weren't completely invisible, so I was able to solve the puzzle, but no bright impressive jets of light anywhere to be seen, and I haven't been able to fix that.
There's also some mild lag when I first enter some ruins or caves, Nchuand Zel caused mild lag upon first entering the great cavern with the water below for example, but the lag stopped after a while and it wasn't the kind of lag that makes you think the game is going to crash. I could still run and even perform a backflip (another mod) in time while fighting the Falmer.
To sum it up, graphics are slightly worse than 360 graphics, mild lag from time to time (mostly in ruins and caves), mods work fine and do not cause additional lag as far as I can tell.
My specs are nvidia geforce 7800GS(256mb), 3GB RAM, intel core 2 6300 (1.86gHz).
