Memory leak ?
I played the game, on high setting (as the auto detector picked) at first it runs great, but after 5 min, the framerate goes so far down its unplayable. I tried it on the lowest settings and it does the same thing.
Anyone else having really bad framerate after a few min? I am quessing its a very bad memory leak, it's unbelieveable.

What do you have Texture Memory Size set to? From what I can tell, you ought to use High (rather than Very High) with a 460, and even then, it'll eventually go above the card's 1GB of VRAM (I'm assuming you have a 1GB 460; if you have a 460 with only 768MBs of VRAM, you ought to use Medium instead).
Edit: You might also try the new beta drivers from nVidia.

I am haveing the exact same problem with my GTX 460 and I am running the current beta driver. Apparently the guys at IGN are having the same problem as I quoted below.
"In fact, I've had to restart the game a number of times to get its erratic framerate issues under control. I'm playing the Steam version of the game, and have tried out Geforce GTX 580 and Radeon 6970 cards on a system with a Core i7 975 CPU and experienced the same issue in both configurations. I crank the settings, keeping SSAO off, and everything seems fine and runs smoothly. Then when a new scene loads, occasionally the framerate plunges into near single digits. I save, quit out of the game, change none of the graphics settings, and when I reload the game everything runs fine. That strikes me as an issue with the game, not my hardware. Am I alone with these issues or are others having problems as well?
Update: After some further searching and installing, I think I may have found a fix for the performance problems. I'm using a GeForce GTX 580 now, installed the beta drivers Nvidia posted, followed advice found on message boards to uninstall 3D Vision drivers and turned off SSAO and Supersampling in The Witcher 2's configuration menu. The result is gameplay that runs at between 50 – 60 frames per second with everything else cranked. Whew. I can't say what a proper fix might be for AMD card users though." -IGN in progress review

After a few minutes my frame rate(no AA, no SSAO, no ubersampling) goes from 60 fps at 60% gpu usage, to 10fps with 15-20% gpu usage. I'm going to go uninstall the 3d vision drivers and see if that helps.
