Nvidia DSR: Understanding DSR Factors and Smoothness

It’s been 5 years since Nvidia launched DSR or Dynamic Super Resolution, the purpose of this feature is to let gamers enjoy a higher resolution on a monitor that doesn’t have native support for the same resolution. For example, a gamer with a 1080p screen can easily game at 1440P or 4K with DSR at the helm. How did Nvidia make it happen? Well, it’s not rocket science.Read: What is dsr smoothness When you enable DSR and increase the resolution, the game engine starts rendering the game at the higher resolution you selected from the settings. It then reduces the resolution to your monitor’s native resolution. I know it all sounds counterintuitive, but in reality, the benefit here is that you’ll be displaying an image with higher resolution and increased sharpness. on DSR you have to know that. You will need a powerful Nvidia GPU if you want to play games with DSR enabled. Something like the RTX 2060 (Entry-Level) or 2080ti (Premium-Level) if you want to play games without interruption in terms of performance on things. In fact, both the benefits and the disadvantages are there. Before going ahead and talking about the top two in DSR, let’s shed some light on some of the benefits and downsides of using Nvidia DSR.

Pros and cons of using Nvidia DSR

This is one of the more important factors that we need to pay attention to. Obviously, if you are increasing the resolution of the game you are playing, there will be some performance error. But is that sacrifice worth it? Let’s take a look at the benefits below.

  • Sharper image quality: If you didn’t already know, YouTubers like LinusTechTips and MKBHD will record videos in 8K with the RED camera, and then downsample those videos to match YouTube’s required resolution. This small downsampling makes the new video look sharper with more detail than before. So is the image quality. If an image is being displayed at 4K and then downsampled to 1080P, the overall quality, as well as the details in the image, will see a significant improvement.
  • Cheaper alternative: The problem with DSR is that it’s available in almost every single Nvidia GPU you’ll find on the market. So that gives you the ability to use this technology without paying a dime for a higher resolution display. However, keep in mind that you will need a GPU that can withstand the increase in display power. Your GPU will have to work harder to efficiently produce the frames you require with DSR. But on the bright side, you won’t have to pay for a new monitor.

  • Increased workload: One of the biggest downsides is that with DSR enabled, your GPU will have to work harder than before. Sure, the increased workload will only happen once you start using DSR effectively in a game, but it’s still a trade-off you’ll have to make. Now, for people with powerful GPUs, DSR processing is not too much of a problem as they can run on higher-than-native resolutions easily. However, if you don’t have a powerful enough GPU, that could be a problem.
  • Visual Artifacts: There is no denying that DSR is constantly improving but another thing that we cannot deny is that some older, or newly released games don’t like to play well with this technology. This leads to visual artifacts which can sometimes be an issue.

So now that you know what are the advantages and disadvantages of DSR, let’s see what’s next? Well, the top determining factors that determine how DSR works are DSR Factor and DSR Smoothness. To understand how both work, we will have to explain some. Let’s have a look.

DSR . factors

If you open the Nvidia Control Panel then go to Manage 3D settings, and scroll down you will find DSR Factor in CUDA core preferences. Now, when clicking on the drop-down menu, you may have trouble understanding what the numbers mean and how they relate to the native resolution written in parentheses. So if you choose the first option which should be 1.20x (native resolution), this means that your monitor’s native resolution will be multiplied by a certain number. So in that case, if your native resolution is 3440×1440, after enabling the first option it will actually become 3768×1577 as shown in the screenshot below.sekiro 2019 04 21 14 36 11 386The higher you go with the elements, the more resolution options you will have, giving you a significant effect on the resolution of the game it will render.

DSR . smoothness

Read more: Main advantage of type iv pfd Now the next part is DSR Smoothness. This is actually more confusing because Nvidia has just given you a slider that you can adjust. Smoothness refers to the sharpness or smoothness that you will find when the image has been scaled. The thing is, once you scale down the image, you’ll start to see some smooth edges. This varies from game to game. The default is 33 percent, but you can adjust it. For comparison’s sake, below you’ll see Sekiro: Shadows Die Twice running at 3768 × 1577 with 33% and 100% smoothness.sekiro 2019 04 21 14 59 30 76433% smoothness at 3768 × 1577 As you can see, the game is definitely sharp, but there are some edges where the sharpness looks jagged. This can be solved with anti-aliasing but that will only affect the game more since you will be running on the upscaled resolution.100 percent100% smoothness at 3768 × 1577 The image above looks a lot smoother at 100%, although there is noticeable blur in the scene. Now this can be solved by turning off anti-aliasing but it can make things worse as each game has different implementation of anti-aliasing, as well as anti-aliasing. What to do is play with the slider until you get to the perfect point where there aren’t too many blurry or jagged edges.

Inference

In conclusion, one thing we are sure of is that DSR is definitely a good feature to have. However, what is worth mentioning about this technology is that it is still not as good as it should be. That’s because it depends on both the hardware, as well as the software and the game engine. Some games respond really, really well to both Factor and Smoothness, while others don’t respond either. If you have to use it because you don’t have a monitor that supports higher resolutions, we recommend playing with the smooth slider, as well as the DSR elements a bit so you can get it right. Tweak the game and see the point where it looks best without asking you to suffer in terms of performance. Read more: What do red and green make up
