Custom Resolution vs DSR Nvidia

[sparkchomp]

I am currently using a custom resolution of 3620 x 2036 for some games on a 1440p monitor, and to me the game looks better than it would on DSR. Are there any downsides to this. Nvidia also put a warning on doing this.

DSR is a weird hack in which NVIDIA take the image in the native resolution,makes it bigger,then sharpens and smooths it.

AMDs VSR is much better,as long as you don't use native resolutions (at native resolutions the image will be at lower resolution)

Custom resolutions are better than both,it should not harm your monitor (the warning is primarily for CRT monitors)

Aside from your odd pick of resolution, to my knowledge you are doing effectively the same thing: rendering the game at a higher resolution followed by downsampling to your monitor's resolution.

How is DSR a weird hack? Isn't it just rendering the image at the higher resolution you set followed by downscaling to your output resolution? The only catch I know of is that you're limited to certain factors times your native resolution, in which case a custom resolution should do the trick if your monitor allows for it.

I already explained that

Nope,that's not how it works.

 

How DSR works:

1.DSR takes the native image

2. makes it bigger by factors times your native resolution

3.Sharpens the image

4.Smooths the image in order to minimize the artifacts of sharpening.

 

That's why the mouse in DSR will be bigger than normal by factors times your native resolution as well.

 

You can change the smoothness and factors times your native resolution in settings.

Hmm it may be a bug or some incorrectly working thing, but I've always understood as DSR never being meant to be used on the desktop, only in games. Never hada the mouse problems you mention when gaming with it. Isn't what you describe just SSAA (would be a tad disappointed/confused if that's all DSR is)?

True

In games it's not a problem,but in desktop it is.

But DSR still has noticeable sharpening and smoothness artifacts,both in desktop and games.

This is the recommended dsr setting (x2) geforce experience recommends for my resolution which 1440p. And it scales perfectly, atleast according to my perception

I found them odd since they're not a clean multiple of 1440p. They're close to square root 2 I see now, so I guess it's somewhat less odd than I initially thought.
