DLSS vs FSR vs XeSS in 2026 — Which Upscaler Should You Use?

Open the settings menu of almost any big game released in the last few years and you'll find the same three options staring back at you: DLSS, FSR and XeSS. All three promise the same thing — more frames per second, essentially for free. But they get there in different ways, they don't look identical, and picking the wrong one (or the wrong preset) can cost you image quality you didn't need to give up. Here's how to choose.

What Upscaling Actually Does

All three technologies work on the same basic idea: the game renders each frame at a lower internal resolution — say 1440p instead of 4K — and the upscaler reconstructs a full-resolution image from that smaller frame, using data from previous frames, motion vectors and (increasingly) machine learning to fill in the detail.

Rendering fewer pixels is dramatically cheaper for your GPU, which is why upscaling became the default rather than a bolt-on. Modern effects like ray tracing and path tracing are so expensive that developers now build performance targets around upscaling being on. Fighting it is mostly a losing battle; the smarter move is knowing which one to use and at what setting. If you're still tuning the rest of your settings menu, our guide to the 7 graphics settings that matter most pairs well with this one.

DLSS: NVIDIA's AI Advantage

DLSS is NVIDIA's upscaler and it's the most restrictive of the three — it only runs on RTX cards, because it leans on the Tensor cores those GPUs carry. In exchange, it's generally considered the image-quality leader, and DLSS 4 widened that lead with a transformer-based model that handles fine detail, hair, fences and fast motion noticeably better than the older approach.

RTX 50-series cards also get multi-frame generation, which can insert multiple AI-generated frames between rendered ones for very large FPS numbers on paper. The caveat: frame generation works best when your base frame rate is already decent (roughly 50–60 FPS before generation), and it adds a small amount of input latency. It's a multiplier, not a rescue tool.

FSR: AMD's Everyone-Is-Invited Approach

FSR's superpower has never been raw quality — it's compatibility. Older FSR versions run on almost any GPU: Radeon, GeForce, Arc, even integrated graphics and aging GTX cards. If you own hardware the other two vendors have left behind, FSR is often the only upscaler available to you, and that alone makes it hugely important.

FSR 4 changed the quality conversation, though. It moved to a machine-learning model that runs on newer Radeon cards, and in most comparisons it closed much of the gap to DLSS — a genuine generational jump. The trade-off is that FSR 4's ML path needs recent Radeon hardware, while the older, more compatible FSR versions tend to look softer in motion, with more shimmer on thin details like grass and wires.

XeSS: Intel's Dark Horse

XeSS is the one people forget about, and it's better than its reputation. On Intel Arc GPUs it uses dedicated XMX hardware and produces results that often land closer to DLSS than to older FSR. On non-Intel cards it falls back to a general-purpose compute path — still usable, just slower and slightly lower quality. If a game offers XeSS and you're on Arc, it should be your default. On other GPUs, it's a legitimate alternative worth eyeballing against FSR.

Head-to-Head Comparison

	DLSS 4	FSR 4 / 3	XeSS 2
Vendor lock	NVIDIA RTX only	Almost any GPU (FSR 4 needs newer Radeon)	Best on Arc; fallback on others
Hardware needed	RTX 20-series or newer	Nearly anything (older FSR); RX 9000-class for FSR 4	Arc for full quality
Image quality	Generally the leader	FSR 4 close behind; FSR 2/3 noticeably softer	Surprisingly strong on Arc
Frame generation	Yes; multi-frame on RTX 50	Yes (FSR 3+)	Yes (XeSS 2)
Best for	RTX owners, ray tracing	Everyone else, older GPUs	Arc owners

Rankings vary by game and version, so treat this as the typical picture rather than a law of nature.

Which One Should You Use?

The practical decision tree is short:

• RTX owner: DLSS Quality first, always. Only try alternatives if a game's DLSS implementation is broken.
• Radeon owner: FSR Quality — and FSR 4 if the game and your card support it.
• Arc owner: XeSS, which runs best on your hardware.
• GTX or older GPU: FSR is your only real option, and it's a good one to have.

Quality vs Performance Modes

Presets control the internal render resolution, and the right choice depends on your output resolution. At 1080p or 1440p, stick to Quality mode — anything lower renders from so few pixels that artifacts become obvious. At 4K, Balanced or even Performance holds up well, because the upscaler still has a lot of source pixels to work with.

That's also why 1080p upscaling shows the most artifacts: Performance mode at 1080p is reconstructing from a 540p image, and no algorithm fully hides that. Our per-game Game Settings pages list which preset each title tolerates best.

Frame Generation: Skip It in Shooters

Remember that generated frames aren't rendered from game logic — they're interpolated guesses, and your inputs aren't sampled during them. In slower single-player games with a healthy base frame rate, frame generation feels like magic. In competitive shooters, the added latency and occasional artifacts around fast-moving objects make it an easy skip. Upscaling: almost always yes. Frame generation: depends on the game.
