4K on a 1080p screen? Nvidia's DSR

[SiggiPalli]

so I was checking the NVidia settings for my moniter and I noticed I could change the resolution to 4k using DSR, I changed and I noticed some difference but I am wondering if this is really 4k or better graphics than the 1080p cause playing 4k on a 144hz would be very usefull, I have a BenQ XL2411 moniter

Your monitor has 1920 pixels horizontally by 1080 vertically, a setting does not by some sort of mystical magic change the physical design of the monitor to now have 3840x2160 pixels.

If there is more then just a placebo difference then the difference is due to the way it changes some other aspect.

You can't play 2k or 4k on a 1080p monitor. Your video card can but your monitor won't allow it. so your graphics card will downscale it to 1080p.

dri?

you mean dsr?

far as i remember its a type of supersampling

may help with smoothing out some things but you will take a performance hit

so not really good for demanding games for one thing

As I understand it, DSR is just a form of supersampling.

Nvidia DSR allows the GPU to render at a higher resolution and then downscale to your screen. This can be useful for making older games look better. However, doing this on newer titles will only reduce performance, so not really any reason to do it on a 144hz 1080p. (Unless you are getting like 500FPS and just want it slightly smoother)

You'd never be able to get a 4k resolution to actually run at 144hz though, unless... it was a still image.

 

[TechyInAZ]

It is virtual 4k not real 4k. Nvidia's DSR is merely an anti aliasing feature, nothing more.
