So this is not exactly new, the driver's been out for 3 weeks now. But I haven't seen a topic here discussing it, and the particular bit about screen scaling makes it a very interesting option for old games on nvidia cards.

Basically it finally introduces a proper fix for scaling to resolutions other than your native one. That means when playing a 4:3 game on a 16:9 or a 16:10 monitor you can now set it to scale to fit the screen while maintaining its original resolution, and it will add black bars to the sides.
If you're a nvidia owner, and you can't find a mod or fix to add widescreen resolutions to your game, this is worth checking out.

What?

THIS SET OF DRIVERS BROKE SCALING FOR ME. >:(

Nothing works now! Everything is force scaled to the full size of the monitor! My black bars are gone!

Let me complete this thread by saying that scaling stayed absolutely the same in my case ;P.

I had fixed-aspect-ratio scaling through my monitor before, but it is certainly nice to have nVidia finally offer proper support over HDMI for GPU scaling like this.

Hoorah!

But... doesn't GPU scaling alter the graphical quality? My monitor perfectly displays the pixelization of old games, while the GPU makes it blurry.

I installed these drivers awhile ago, but it made STALKER :SoC Complete run like total ass (20 fps) so I went back to 270.61

Nvidia's drivers have had aspect ratio options for years, they just renamed it and changed its location on the control panel. It tends to work better now.

However for many people it actually wouldn't show up (being connected to a monitor that supported HDCP seemed like a potential factor). On previous driver versions I had to do a stupid dance where I changed res to 1024x768, then the scaling appears, then I select the option I want (it appears to be reset to the default, but takes effect anyway), then I switch to my standard resolution. No need for that any more.

Heh, never had a problem with aspect ratio on my GeForce cards. Not a single one :-P
