Imagine this: you’re engrossed in a breathtaking game world, everything rendered in crisp detail. But suddenly, the frame rate dips, causing a stutter that throws you off your rhythm. The desire for stunning visuals and smooth gameplay is a constant struggle for PC gamers. This is where upscaling technologies like DLSS (Deep Learning Super Sampling) and FSR (FidelityFX Super Resolution) come in.

They offer a clever solution: rendering the game at a lower resolution and then intelligently upscaling it to match your monitor’s native resolution. The result? Potentially buttery-smooth frame rates without sacrificing too much image quality. But which upscaling tech reigns supreme? Let’s delve into the nitty-gritty of DLSS vs. FSR to help you decide.

What is DLSS (Deep Learning Super Sampling)?

Think of DLSS as a master of disguise. It leverages the power of artificial intelligence (AI) to transform a lower-resolution image into a higher-resolution one that looks darn close to the real deal. Here’s the magic trick: Nvidia’s RTX GPUs boast specialized hardware called Tensor Cores, which are specifically designed for AI tasks like DLSS. These Tensor Cores take a low-resolution image, analyze sharp edges and intricate details, and then reconstruct them in the final, higher-resolution image. The benefits? A significant boost in performance (think smoother frame rates) and image quality that often rivals native resolution.

What is FSR (FidelityFX Super Resolution)?

While DLSS takes the AI route, FSR from AMD operates differently. It’s an open-source upscaling solution, meaning it’s not tied to specific hardware and can potentially work on a wider range of graphics cards, including those from AMD, Nvidia, and even integrated graphics. FSR relies on a spatial upscaling technique, analyzing sharp edges and colors in the low-resolution image and then intelligently recreating them at a higher resolution. FSR comes in different flavors, with FSR 1.0 offering a simpler approach and FSR 2.0 introducing more advanced algorithms for improved image quality. The key advantage of FSR? Broad compatibility and a noticeable performance boost, making it a great option for gamers with a wider range of hardware.

DLSS vs. FSR: A Head-to-Head Comparison

Now, let’s get down to brass tacks and compare DLSS and FSR across key aspects.

Image Quality


Here, DLSS often takes the crown. Its AI tech excels at preserving details and sharpness, especially in fast-moving scenes. FSR can sometimes introduce minor artifacts (visual glitches) or a slight softness compared to native resolution. However, the gap is narrowing with FSR 2.0, and the difference might be negligible for some gamers at higher resolutions like 4K.

Performance Gains

Both DLSS and FSR can significantly improve frame rates. DLSS might hold a slight edge, particularly at lower resolutions, thanks to its dedicated hardware acceleration. However, FSR’s performance gains are impressive too, especially considering its broader compatibility.


This is where FSR shines. It can potentially work on a wider range of graphics cards, including older models and those from AMD. DLSS, on the other hand, is exclusive to Nvidia’s RTX series GPUs.

Ease of Use

Both technologies are fairly straightforward. Game developers typically integrate them into their titles, and users can enable them from the game’s graphics settings menu.

Final Thoughts

So, which upscaling tech should you choose? It depends on your priorities. If you have an Nvidia RTX GPU and prioritize top-notch image quality with the best possible performance boost, DLSS is a compelling option. However, if you have a wider range of hardware or prioritize compatibility, FSR is a fantastic choice. Both technologies are constantly evolving, so the future looks bright for upscaling, offering gamers even more options for achieving that sweet spot of stunning visuals and smooth gameplay.


Q. Is DLSS better than FSR?
A. It depends. DLSS often offers superior image quality, especially at lower resolutions. However, FSR boasts broader compatibility and can still deliver impressive results.

Q. Does FSR work on my graphics card?
A. FSR has wider compatibility compared to DLSS. Check the game’s supported features or AMD’s website for confirmation.

Q. How much performance improvement can I expect with DLSS/FSR?
A. The boost varies depending on the game, resolution, and graphics settings. However, frame rate increases of 30% or more are not uncommon.

Q. Does DLSS/FSR impact image quality?
A. Yes, both technologies can affect image quality. DLSS, while generally excellent, might introduce minor shimmering effects in some scenarios. FSR can sometimes lead to a slight softness compared to native resolution. The impact can vary depending on the specific game, upscaling mode used (e.g., DLSS Quality vs. Performance), and personal perception.

Q. How can I decide between DLSS and FSR?
A. Consider your priorities. If you own an Nvidia RTX GPU and crave the best possible image quality with maximum performance gains, DLSS is a strong contender. If you have a wider range of hardware or prioritize compatibility, FSR is an excellent choice. Ultimately, trying both technologies in games that support them can help you determine your personal preference.
