DLSS vs FSR Explained: Upscaling, Frame Generation and GPU Support
Open the settings of any modern game and you will find options like DLSS, FSR and Frame Generation, each promising better performance. But what is the actual difference? And does every graphics card support everything? In this article we explain DLSS vs FSR in simple terms, and separate two things people often mix up: upscaling and frame generation. Everything here comes from the official NVIDIA and AMD pages.
The basic idea: why do we need these technologies?
A graphics card works harder as resolution goes up. Drawing a 4K image means drawing far more pixels than 1080p, and that hits smoothness directly. The clever idea: instead of rendering every pixel at full resolution, the card renders at a lower resolution, then a smart technique rebuilds the image at a higher resolution. The result is less load on the card and an image close to native resolution.
There is a second, completely different idea: instead of improving each frame, add new frames between the ones the card rendered. That is frame generation. The two can work together, but each works differently.
What is DLSS?
According to NVIDIA, DLSS is "a suite of neural rendering technologies that uses AI to boost FPS, reduce latency, and improve image quality." So DLSS today is not one feature but a family, mainly:
- Super Resolution: outputs higher-resolution frames from a lower-resolution input. Supported on RTX 20, 30, 40 and 50.
- Ray Reconstruction: improves the quality of ray-traced scenes. Supported on RTX 20, 30, 40 and 50.
- DLAA: AI anti-aliasing without lowering resolution, for maximum image quality. Supported on RTX 20, 30, 40 and 50.
- Frame Generation: generates extra frames while maintaining responsiveness with NVIDIA Reflex, according to NVIDIA. Supported on RTX 40 and 50 only.
- Multi Frame Generation: according to NVIDIA, generates up to five frames per rendered frame. RTX 50 only.
- Dynamic Multi Frame Generation: a dynamic version of multi frame generation, exclusive to RTX 50.
The key point: DLSS relies on dedicated hardware in RTX cards, so it does not run on AMD cards or older NVIDIA GTX cards.
What is FSR?
FSR stands for AMD FidelityFX Super Resolution. According to AMD, FSR is now a suite too, mainly:
- FSR Upscaling (formerly FSR 4): reconstructs crisp, high-quality visuals from low-resolution frames.
- FSR Frame Generation: according to AMD, "predicts and inserts new frames between rendered ones."
- FSR Ray Regeneration and FSR Radiance Caching: technologies aimed at ray-traced scenes and lighting.
FSR's big historical advantage was that it was open to many cards. But full support for the newest versions is now tied to recent AMD cards, as shown below.
Who supports what? Compatibility table
A summary of compatibility based on both companies' pages:
| Technology | Supported cards |
|---|---|
| DLSS Super Resolution, Ray Reconstruction, DLAA | NVIDIA RTX 20 / 30 / 40 / 50 |
| DLSS Frame Generation | NVIDIA RTX 40 / 50 |
| DLSS Multi Frame Generation | NVIDIA RTX 50 only |
| FSR "Redstone" (full support) | AMD Radeon RX 9000 and above |
| FSR "Redstone" (upscaling only) | RX 6000 and RX 7000, plus some Ryzen AI and Ryzen Z2 processors |
| FSR 3 frame generation | RX 5000 and above |
| FSR 3 upscaling and FSR 2 | RX 590 and above |
| FSR 1 | RX 400 and above |
Important note: AMD states on its page that it does not provide technical or warranty support for FSR enablement on other vendors' graphics cards. You may find FSR running on an NVIDIA card in some games, but AMD does not guarantee it.
Upscaling vs frame generation: the difference you need to know
Upscaling reduces the load on the card because it renders at a lower resolution, so each frame comes out faster. That means more "real" frames rendered by the card itself, and you usually feel the difference in smoothness and responsiveness.
Frame generation does not render frames faster; it adds frames between rendered ones. Motion looks smoother on screen, but generated frames are not the direct result of your input. That is why NVIDIA pairs Frame Generation with Reflex to maintain responsiveness.
The practical rule: upscaling helps in most cases, while frame generation works best when you already have decent base performance and want smoother motion on a high-refresh display.
So which should I choose?
The right question is not "is DLSS better than FSR?" It is: which card do you have?
- NVIDIA RTX card: try DLSS first, since it is designed for your card's hardware. On RTX 50 you can use Multi Frame Generation in supported games.
- AMD Radeon RX 9000: you get the full FSR suite, according to AMD.
- Older AMD card or a card without DLSS support: FSR remains your option, and which version depends on your card generation per the table above.
- Remember: each game chooses what it supports. Not every game has every technology, so check the game's own settings menu.
Cards available at GamerZone that support these technologies
- MSI GeForce RTX 5080 VENTUS 3X OC 16GB GDDR7: an RTX 50 card, so it supports the full DLSS suite including Multi Frame Generation in supported games. Check the current price on the product page.
- ASUS Prime Radeon RX 9070 XT OC Edition 16GB GDDR6: an RX 9000 card, the class AMD says has full FSR "Redstone" support. Check the current price on the product page.
FAQ
Does DLSS work on AMD cards?
No. According to NVIDIA, DLSS technologies are supported on GeForce RTX cards only.
Does FSR work on NVIDIA cards?
Some FSR versions may run in some games, but AMD states it does not provide technical or warranty support for FSR on other vendors' cards.
Does frame generation increase real performance?
Frame generation inserts frames between rendered ones, so motion looks smoother. It is different from upscaling, which reduces the load on the card itself, and it works best when base performance is already good.
I have an RTX 30 card. Can I use NVIDIA Frame Generation?
According to NVIDIA, DLSS Frame Generation is supported on RTX 40 and 50 only. Your RTX 30 card supports Super Resolution, Ray Reconstruction and DLAA.
What is the difference between FSR 4 and FSR Upscaling?
According to AMD, FSR Upscaling is the new name for FSR 4.
Do I need to enable these in every game?
No. If your card runs a game smoothly at native resolution, you can use DLAA or skip upscaling for top image quality. These technologies help most when you want a higher resolution or refresh rate than your card can handle natively.
Bottom line
DLSS and FSR share one goal: a great image with higher performance. The difference is in how they work and which hardware supports them. Understand upscaling vs frame generation, know your card's generation, and you will know exactly what to enable. Torn between NVIDIA and AMD?
