DLSS 4 vs FSR 4: Which Upscaler Wins?
Both are ML-based now. The gap narrowed — but it didn't close.
Quick Verdict
DLSS 4 still wins on image quality, frame generation quality, and game support. FSR 4 is a massive leap over FSR 3 and finally competitive — but only on RX 9000-series cards. If you have an RTX card, DLSS is the obvious choice. If you have an RX 9070/9070 XT, FSR 4 is genuinely good. Anything older AMD: you're stuck with FSR 3.x quality.
DLSS 4 — What's New
- Transformer-based super resolution — replaces the CNN model used since DLSS 2. Sharper, fewer artifacts in motion.
- Multi Frame Generation — RTX 50 only. Generates up to 3 frames per rendered frame (4x effective FPS).
- Ray Reconstruction — better RT denoising, available on all RTX cards.
- Backwards compatible — RTX 20/30/40 owners still get the new transformer model via DLSS Override.
FSR 4 — What's New
- ML-based for the first time — FSR 1-3 were spatial/temporal; FSR 4 uses on-die ML accelerators.
- RX 9000 series only — RDNA 4 has dedicated AI hardware. Older RDNA 2/3 cards stay on FSR 3.x.
- Frame Generation 2.0 — improved over FSR 3 FG, fewer ghosting artifacts.
- Open source path — AMD still publishes the algorithm; the ML model is RDNA-4-locked but the rest is portable.
Image Quality Comparison
| Aspect | DLSS 4 | FSR 4 |
| Static image quality | Excellent | Very good |
| Motion stability | Excellent | Good (mild ghosting) |
| Disocclusion | Excellent | Improved over FSR 3 |
| Performance preset usability | Yes (Performance is fine) | Quality preset only |
| Frame Gen quality | Excellent (Multi Frame Gen) | Good (single FG) |
Game Support
DLSS: 600+ games at last count, with day-1 support for nearly every AAA release. FSR 4:~30 games at launch, growing — but most new games still ship FSR 3 first. AMD's strategy of upgradeable presets helps: many FSR 3 games can be force-upgraded to FSR 4 via driver overlay on RX 9000.
Which Should You Use?
| RTX 50 owner | DLSS 4 + Multi Frame Gen — no contest |
| RTX 40/30/20 owner | DLSS 4 transformer model (no MFG) |
| RX 9070/9070 XT owner | FSR 4 — finally competitive |
| RX 7000 / 6000 owner | FSR 3.1 (FSR 4 not supported) |
Bottom Line
DLSS 4 is the better tech in 2026, and the gap is mostly about game support, not raw quality anymore. FSR 4 is finally good enough that AMD GPUs are no longer disadvantaged in upscaler-heavy titles. If you're cross-shopping RTX 5070 Ti vs RX 9070 XT, upscaling is no longer the deciding factor — performance, price, and ecosystem features are.
