I just received my new gtx 980 evga SC, first time using DSR to 4k... Not sure how its works, i mean when i tried a game in 4k with dsr and come back to my background, my icon are everywhere... -_- each time and its impact alots my fps ... My monitor is a benq xl2411z 1080p . Should I stay in 1080p with ultra graphics or drop down graphics and use dsr 4k ? Whats the best? Any opinion please :)? Thx
If i put 4k in my background, I don't like that its like not normal...

I don't know if anyone will be able to tell you what looks "best". Why don't you just try both and see what you prefer?

DSR is just an anti-aliasing technique. Running DSR at 4K means your GPU is effectively rendering the game at 4K (before it's scaled down to your monitor's resolution), so it's obviously going to be very taxing on your GPU.

DSR is not "just an anti-aliasing technique" It completely different. DSR is when the frames are rendered at a higher resolution and than downscaled to the monitor resolution

Because the game is being rendered in 4k you will have lower FPS. but the benefit usually is you don't need to have AA on for a crisp image. So like for an example Diablo 3 DSR 4k looks better than 1080p and still has 100+ fps.

So it works as Anti-aliasing.
Nobody claimed it was an AA technique, but rather thats what the 4k render scaled down to 1080p accomplishes.

I personally like the look of higher graphics over downscaled higher resolution.

Yes, it is just a form of anti-aliasing, known as super-sampling anti-aliasing (SSAA). DSR is just Nvidia's name for their driver-implemented version of it, much like VSR is AMD's name for their version.

As compared to referencing Nvidia promotional materials? But fine, if you don't like my wiki link, read this:

"Dynamic Super Resolution (DSR) is a feature that has the potential to reduce jaggies at the edge of pixels, an effect known as 'aliasing'. Put simply, DSR is a form of anti-aliasing."

"SSAA renders a game at a higher resolution than the game is set to display, and downsamples the result to the target resolution [...] What Nvidia offers with DSR is a way to deliver supersampling antialiasing while bypassing the game's built in anti-aliasing limitations completely."

As I said, it's simply SSAA implemented at the driver level.

Sounds to me like you're setting your desktop resolution to 4K, which really isn't recommended.

The way to use DSR is:
1) Check all the "DSR Factor" boxes in the Nvidia Control Panel under the Global Settings tab.
2) Set your game resolution in-game using the game's Video settings, up to 4K, if your system can handle it.

The key is to understand that you only enable DSR with the Nvidia Control Panel. You set the actual game resolution from within the game's menu. Basically, you'll now have access to in-game resolutions above your native 1080. Leave your desktop at 1080 native resolution in order to avoid weird icon behavior.

I leave my destoo at 1080p but each time I run a game and set it to 4k, when i come back at desktop, all icon moved everywhere... It's frustrating. I didn't check anything in nvidia control panel also.. I will go check that , do you have to uncheck to come back at 1080 in game ? Sorry noob here lol... Another thing, if dsr act like a AA should i turn down AA to FXAA for exemple to get more fps ?

No need to touch the Nvidia Control Panel. Are you playing in full screen mode or windowed mode? Maybe that makes a difference. The game itself may not work so well with reverting back to normal desktop. I suggest you lower your in-game resolution a bit and see if that helps. Play around with it.

Turning down AA levels is an option and one of several tweaks you can do for balance, in addition to adjusting DSR levels. I'm on the side that DSR has a similar effect as antialiasing, but is not the same as antialiasing.

I play in fullscreen but I think what affect my icon is when I press alt/tab to come back to desktop and come back at game, this cause my icon to go everywhere... I think. Well im wondering also if its better to play with higher resolution and droping graphic or leave at 1080p and max out everything... Im confuse

Maybe getting a bit off topic here, but why do you say that? If you read either of the links I've posted, or simply look up SSAA on your own, you'll see that DSR is the very definition of SSAA, which in turn is one of the oldest and most fundamental forms of AA. Now, there are many forms of AA out there, and each will perform differently. So SSAA is very different than post-processing AA like FXAA, in terms of implementation, results, and performance impact. But that doesn't change the fact that both are forms of AA.

I just don't get why people keep ignoring/disagreeing with what I'm saying, while providing no evidence to the contrary. DSR isn't just like AA, nor does it just achieve some of the same effects as AA; it is AA, or rather, one form of it.

Ah, the alt-tabbing seems like the issue. I'm guessing that the resolution doesn't bounce back and forth between the desktop and the game when you alt-tab, so you're forcing the game's resolution onto your desktop when you do that. Try quitting the game normally using the menu option.

It's always good to play around with your settings to find the right mix of quality and performance. Usually I begin with full settings at native 1080 resolution, then add or subtract from there. If I have plenty of performance in reserve, then I'll up the DSR resolution as the final measure. I usually don't go above 1440 though with most of the games I'm playing.

I agree.

Again, I'm not sure someone else can answer this for you, as it's a somewhat subjective question. What one person thinks looks the best won't necessarily be the same as another person. Just try out both and see which looks better to you.


Thank you, it felt like I was going crazy, haha.

The reason I say it's not exactly the same as supersampling is that there is a little more processing involved than simple SSAA.

Quote:
In general DSR works like downsampling, but it has simple user on/off control. Textures will now be sampled at higher resolutions that equates to more pixels being sampled. Then a filter is applied (13 TAP Gaussian). This high quality filter reduces or eliminates AA artifact experiences with normal down-sampling, which relies on a simpler box filter.

It's hardly enough difference to argue over or to highjack a thread over.

I did the test and even if I quit the game corectly without any alt-tab, my icon still goes everywhere ? what the... !! i like to put my steam game on the right etc....every time i play a game with DSR, when i come back at desktop, icon are top .....no body around here got the same issue ? it EVERY time not juste once....EVERY damn time
