1440P NVidia DSR no AA vs Native 1080p w/ AA?

Quick explanation of DSR: NVidia has this nifty feature called DSR (Down Scale Resolution), which allows you to run an application at a larger resolution than what your monitor/TV can natively support.

What do you guys think of using DSR to eliminate Aliasing?

I've tried 1440p DSR to 1080p on Skyrim and The Witcher 3, running on a GTX 980 EVGA Superclocked GPU w/ i7 4790k. The results are quite good. DSR allowed me to use only 2x AA and still have less noticeable aliasing compared to native 1080p with full AA enabled and NO performance hit.

 

I have seen my son do it with his desktop GTX 970. He has a 1080p monitor and I like the way it looks better than AA.

The only thing I have noticed about DSR which I do not like, is the game's text is smaller. I play on a 42" 1080p TV and sit about 10 feet away. (playing with wireless XBONE controller). Most newer games (Witcher 3) can actually scale their text so it's not always an issue, and I can accomplish the same effect by downloading a bigger font mod for Skyrim.

 

DSR is great but with the disadvantage you pointed out of the smaller text. Great for things like FPS for example but not so much for RPGs.

 

I'd rather have the in game form of super sampling/rendering at highe res in game with proper scale.

 

DSR is less if a performance hit though.

 

Oh yeah, I don't doubt that for a second. I meant I prefer the scale/super sampling for image quality, mainly for what was already pointed out (smaller text, though I also find image a bit blurry at times with DSR).

 

Adjust the smoothness on DSR to get rid of the blurry effect at the cost of a bit of performance. DSR is a trade off between image quality and performance. It's all a balancing act whereas SSAA and such have a sharp performance impact.

 

I like controllers........*hides from the mob.

I havent had much experiences with it yet but I do prefer raw SSAA/downsampling over other types of AA.

 

I messed with the smoothness and tried to use 1.78 for 1440p resolution, but I never got a satisfactory result

It's a nice feature though.

 

I don't usually use DSR unless it's for 4K. 1440p never looks right.

 

Hmm why do you say that?

yea hes right 4k to 1080p is a 4x bicubic resize without the guassian filter

so it looks nicer to do 2160p to 1080p instead of 1440p to 1080p. The OP is using 2.25x or 1.75x or something

 

Thanks for the explanation, I had no idea what the reason was I just noticed it scaled weird lol

 

To be fair, the image can sometimes look a little... off. Particularly if you are looking at an object with perpendicular lines (a chain-linked fence for example), though I usually turn it into a positive thing by thinking "When have you ever seen a PERFECT fence?" And this can also be alleviated with DSR smoothing, as some of you have already mentioned.

I'm all about maximizing image quality with as little performance hit as possible, which is why I'm in love with DSR right now.

 

How are you all doing DSR on notebooks? Mine still doesn't have the option (Optimus).

 

You will never have the option.
