New Nvidia driver brings DSR support to Fermi and Kepler GPUs

AFAIK DSR does not allow for custom resolution (define your own resolution instead of using default one that supported by monitor or game). instead they use factor based on your monitor native resolution. for example 2 times or 3 times your resolution. it is not been disabled. it is simply not available in DSR. it is one of DSR restriction for those like to use custom resolution. but maybe you can use custom resolution in the future. nvidia is listening to feed back. Shadowplay when it first come out it has little option to it.
 



All DSR is, is the rendering of a custom resolution. Nvidia has dressed it up and given you some fancy ways of handling it. That doesn't change the fact DSR is not a new feature they just made it more accessible. If you create a custom resolution for of 5120*2880 that is the equivalent of using Nvidia DSR @ 4.00 on a 1440p monitor.

Creating custom resolution is still available with an individual card, SLI disabled. Just like DSR is available with SLI disabled. I should also mention that I am using a Gsync monitor (Asus swift) . I believe the issue is with Gsync or SLI not DSR.


 
DSR work just fine with with my 660 SLI. DSR + SLI + G-Sync monitor will not work as of now. it is known issue. people reporting that enabling SLI even without G-Sync monitor will not let them use DSR. but it seems doing clean install using DDU solve the problem for some.
 


It's actually better - since they use an internal rendering, the mouse is the same size as normal - which was one thing I didn't like about Custom resolutions.

Also the adjustable softness is a nice new feature - 30% replicates the softness of FXAA, but with more texture clarity and less transparency artifacts. (Tested in Batman AC)
 
Just a question to those out there with a low end/budget GPU such as a GT 610, GT 720 or something around that.

How well does DSR work for you in terms of quality and performance. Because I do know that this puts a ton of stress on low end GPUs having to scale everything up and back down. Obviously I'm not talking about running games like Crysis 3 or Rise of the Tomb Raider. But in benchmarking terms.
