I've been using this new driver for a few days now with my GTX 285 and it seems fine.
It's the first one with OpenGL 3.2, BTW.
Now if we could only get the 3D app developers to actually start using the advancements these newer drivers offer, we'd be getting somewhere. ;-)

Seems to do just fine with all my 3D apps. I don't have Poser installed at the moment because I just got a new HDD and reinstalled Windoze and my main programs and haven't gotten around to Poser yet, but I'm sure it's fine with Poser too.

One thing I can say is with the last driver, under Windows 7 x64, a few of my games were showing some artifacting, particularly in Far Cry 2, but that's all gone now.
