Does DLSS Really Boost Graphics Card Performance?
For many PC gamers, graphics are a crucial part of the gaming experience. The more immersive and realistic the graphics, the more enjoyable the gameplay. However, achieving high-quality graphics can come at a cost, often requiring powerful graphics cards to run smoothly. This is where DLSS comes in.
DLSS, or Deep Learning Super Sampling, is an AI-based technology developed by Nvidia that aims to boost graphics card performance and increase the quality of graphics in video games. But the question is, does DLSS really work? And is it worth enabling for gamers? In this post, we will explore DLSS in detail, including how it works, the impact it has on frame rates, and whether it is worth enabling.
What is DLSS?
Before looking at whether DLSS really works, it’s important to understand what it is. DLSS is an AI-based technology that uses deep learning algorithms to improve image quality in video games. It does this by rendering graphics at a lower resolution than the native resolution of the display, then using AI to upscale the image back to the display’s native resolution. This results in higher frame rates, smoother gameplay, and improved image quality.
The DLSS technology uses Tensor Cores, which are specialized hardware within Nvidia graphics cards that are designed to perform matrix operations and other deep learning tasks. These Tensor Cores are used to train the DLSS algorithm on specific gaming scenarios, resulting in improved performance for particular games.
How Does DLSS Work?
DLSS works by using AI algorithms to upscale lower-resolution images to higher resolutions. When a game is played with DLSS enabled, the graphics card renders the game at a lower resolution than the native resolution of the display. For example, if the display has a native resolution of 1080p, the game may be rendered at 720p when DLSS is enabled.
The lower-resolution image is then processed by the DLSS algorithm on the graphics card. The DLSS algorithm uses the Tensor Cores on the graphics card to analyze the image and determine how to upscale it to the native resolution of the display. The algorithm is trained on specific gaming scenarios, so it knows exactly how to upscale the image for a particular game.
Once the image has been upscaled, it is displayed on the screen at the native resolution of the display. The result is a higher-quality image that looks just as good, if not better, than if the game had been rendered at the native resolution of the display.
Is DLSS Worth Enabling for Gamers?
Now that we know how DLSS works, the next question is whether it is worth enabling for gamers. The answer is not straightforward and depends on a few factors, including the game itself, the graphics card, and the display.
One of the main benefits of DLSS is that it can increase frame rates, resulting in smoother gameplay. However, the impact of DLSS on frame rates varies depending on the game and the graphics card used. Some games may see a significant boost in frame rates when DLSS is enabled, while others may see little to no improvement.
Another benefit of DLSS is that it can improve image quality. However, this is also game-dependent. Some games may see a noticeable improvement in image quality with DLSS enabled, while others may not see much of a difference.
The graphics card used also plays a role in whether DLSS is worth enabling. DLSS is only available on Nvidia graphics cards that have Tensor Cores, which includes the RTX 20 series and newer. If you have an older graphics card, then DLSS is not an option.
Finally, the display used can also impact whether DLSS is worth enabling. DLSS is most effective on displays with high resolutions, such as 4K. If you have a lower-resolution display, then the benefits of DLSS may not be as noticeable.
Ultimately, whether DLSS is worth enabling for gamers depends on a variety of factors, and it’s up to each individual to determine whether the benefits outweigh the potential downsides.
How Much of an Impact Does DLSS Have on Frame Rates?
One of the main reasons that gamers may want to enable DLSS is to increase frame rates. But how much of an impact does DLSS actually have on frame rates? The answer is, once again, game-dependent.
In some games, DLSS can result in a significant boost in frame rates. For example, a study by PC Gamer found that enabling DLSS in Control increased frame rates from 71 fps to 94 fps, a 32% improvement. Similarly, enabling DLSS in Metro Exodus increased frame rates from 58 fps to 99 fps, a 71% improvement.
However, not all games see such a drastic improvement with DLSS enabled. In some games, enabling DLSS may result in only a slight improvement in frame rates, or no improvement at all. For example, enabling DLSS in Shadow of the Tomb Raider resulted in only a 3% improvement in frame rates, according to the same PC Gamer study.
The impact of DLSS on frame rates also depends on the graphics card used. Generally, the newer and more powerful the graphics card, the more of an impact DLSS will have on frame rates. For example, enabling DLSS in Control had a greater impact on frame rates when using an RTX 3080 graphics card than when using an RTX 2060 graphics card.
Conclusion
In conclusion, DLSS is an AI-based technology that can improve graphics card performance and increase image quality in video games. However, the impact of DLSS on frame rates and image quality varies depending on a variety of factors, including the game, the graphics card, and the display. Despite this, DLSS is worth considering for PC gamers who want to squeeze the most performance and quality out of their graphics card, particularly if they have a newer Nvidia graphics card with Tensor Cores. As with any technology, it’s important to test DLSS in a variety of scenarios to determine whether it’s worth enabling for your specific use case.
