Modern upscalers render your game at a lower internal resolution and intelligently reconstruct it to your screen resolution, buying you a large frame rate boost for a small image-quality cost. The three big names, NVIDIA DLSS, AMD FSR, and Intel XeSS, do the same job differently, and which one to pick depends mostly on your GPU. Here is a practical comparison.

Top 3 picks at a glance
How the three differ
DLSS (NVIDIA)
DLSS uses dedicated AI hardware on NVIDIA RTX GPUs and generally delivers the best image quality, especially in motion, with clean edges and stable detail. The trade-off is that it only runs on RTX cards.
FSR (AMD)
FSR is open and runs on almost any GPU, including older and non-AMD cards. That broad compatibility is its superpower. Image quality has improved a lot across versions, though in fine motion it can trail DLSS slightly.
XeSS (Intel)
XeSS runs best on Intel Arc GPUs with their AI hardware, but also works on other vendors’ cards in a compatible mode. Quality sits between the other two in many titles, making it a strong option for Arc owners and a good fallback elsewhere.
| Upscaler | Runs on | Image quality | Best pick for |
|---|---|---|---|
| DLSS | NVIDIA RTX only | Top tier | RTX GPU owners |
| FSR | Almost any GPU | Good, very broad | AMD, older, or mixed setups |
| XeSS | Best on Intel Arc, works elsewhere | Strong | Arc owners, fallback |
Choosing a quality mode
Each upscaler offers modes from Quality to Performance. Quality renders at a higher internal resolution (around 67% of target) for the best image, while Performance renders lower (around 50%) for the biggest FPS gain. A good rule: at 4K you can use more aggressive modes because there are more pixels to reconstruct from; at 1080p stick to Quality to avoid softness.
Match the mode to your resolution
At 1440p, Quality or Balanced usually looks great and adds 30 to 60 percent FPS. At 4K, Performance mode can nearly double frame rates while still looking sharp. At 1080p, only Quality mode tends to hold up well.
The simple decision
If you own an RTX card, use DLSS, it is the best available to you. If you have an AMD or older GPU, use FSR. If you own an Intel Arc card, use XeSS. When a game offers only one of them, use whatever is present; any modern upscaler in Quality mode is a smart trade of a little sharpness for a lot of performance.
Keep the upscaler version current
All three upscalers improve with new releases, and the version bundled with a game may be older than the latest available. Newer versions reduce shimmering, ghosting behind moving objects, and smearing on fine detail like foliage and hair. Some games let you update the upscaler through their settings or a patch, and the difference between an early and a recent version can be the gap between “obviously upscaled” and “looks native.” When you compare upscalers in a specific game, judge them on that game’s implementation, since a title with a modern DLSS and an old FSR is not a fair fight, and a fresh FSR build may close much of the quality gap.
FAQ
Does upscaling make games look blurry?
In Quality mode at 1440p or 4K, most people cannot tell in normal play, and edges can even look cleaner than native. Blur mainly appears in aggressive Performance modes at low resolutions like 1080p.
Is upscaling the same as frame generation?
No. Upscaling reconstructs a higher-resolution image from a lower-resolution render. Frame generation inserts extra frames between real ones. They can work together but solve different problems.
Bottom line
Pick the upscaler that matches your GPU: DLSS on RTX, FSR on AMD or older cards, XeSS on Intel Arc. Use Quality mode at 1080p, be more aggressive at 4K, and you will gain substantial frame rate with an image most players cannot distinguish from native.
