Fortnite's support for both DLSS (NVIDIA's Deep Learning Super Sampling) and FSR (AMD's FidelityFX Super Resolution) gives players on a wide range of hardware a meaningful performance boost - but choosing the wrong upscaler for your GPU can cost you clarity, consistency, or competitive frame rates. This guide breaks down exactly which upscaler wins in Fortnite and why it depends significantly on your GPU.
Quick Answer
Which is better in Fortnite - DLSS or FSR? DLSS produces sharper, more temporally stable images on NVIDIA RTX GPUs and is the better choice if you own one. FSR is GPU-agnostic and runs on AMD, NVIDIA, and Intel GPUs, making it the only upscaling option for AMD GPU owners and a solid alternative on older NVIDIA hardware that lacks Tensor cores. At equivalent quality modes, DLSS edges ahead on image quality; FSR closes the gap significantly at FSR 2 Quality mode.
🔧 How Each Upscaler Works in Fortnite
DLSS in Fortnite Fortnite supports DLSS 3.5 (on RTX 40-series) including Frame Generation, which synthesises additional frames between rendered frames to boost perceived frame rate. On an RTX 4070, DLSS Performance mode at 1080p can deliver 200+ FPS in Fortnite's build mode, maintaining the temporal stability that matters for tracking fast-moving opponents.
DLSS uses dedicated Tensor cores on NVIDIA RTX GPUs (RTX 2000 series and newer). These cores handle the AI upscaling workload independently of the CUDA cores doing the actual game rendering, meaning upscaling has near-zero performance cost on the primary render budget.
FSR in Fortnite Fortnite supports AMD FSR 2 (also called FSR 2.x or FSR2), which uses a temporal algorithm similar to DLSS but executed entirely on shader cores - meaning it runs on any GPU that supports DirectX 11 or 12. FSR 2 Quality mode in Fortnite renders internally at about 67% of output resolution and is noticeably better than FSR 1 (which was purely spatial).
On AMD Radeon RX 7000 series GPUs, FSR 2 runs efficiently. On NVIDIA GPUs, FSR 2 works but consumes some shader performance that DLSS offloads to Tensor cores - a minor disadvantage that rarely matters in Fortnite's relatively GPU-light rendering.
📊 DLSS vs FSR Performance Comparison in Fortnite
| Setting | Resolution | Approx. FPS Gain vs Native | Image Quality |
|---|---|---|---|
| DLSS Quality | 1080p / 1440p | 25–40% | Excellent, sharp foliage |
| DLSS Performance | 1080p / 1440p | 50–70% | Good, minor shimmer on text |
| DLSS Frame Gen (RTX 40) | 1080p / 1440p | Up to 90% perceived | Excellent |
| FSR 2 Quality | 1080p / 1440p | 20–35% | Good, slight edge softness |
| FSR 2 Performance | 1080p / 1440p | 40–55% | Acceptable, noticeable at 1080p |
| FSR 2 Ultra Quality | 1080p / 1440p | 10–18% | Near-native |
Benchmarks are approximate and vary by scene - Fortnite's performance varies significantly between zero-build mode (less geometry, higher FPS) and creative/festival modes (more complex, lower FPS).
Competitive recommendation: For competitive Fortnite at 1080p targeting 144Hz or 240Hz:
- RTX GPU: Use DLSS Performance or DLSS Quality. Avoid Frame Generation if your base frame rate is under 60 FPS - Frame Gen adds latency at low base frame rates.
- AMD GPU (RX 6000/7000): Use FSR 2 Quality. FSR 2 Performance at 1080p on a 24-inch monitor introduces visible softness that can affect target identification at range.
💡 In-Game Settings for Best Results
Disable temporal anti-aliasing (TAA) when using DLSS or FSR: Fortnite sometimes allows both to be enabled. Running TAA alongside an upscaler causes double-processing blur. Set AA to Off or Epic only when not using an upscaler.
Sharpening filter: Both DLSS and FSR benefit from a modest in-game sharpening pass (set to 50–60%). Avoid maximum sharpening - it introduces haloing around player models and building edges.
Rendering mode: Ensure your rendering mode is set to DirectX 12 in Fortnite settings for DLSS 3 and FSR 2 support. DirectX 11 supports older versions of both upscalers with lower quality.
Frame rate cap: Set a frame rate cap in Fortnite's settings at 5 FPS below your monitor's refresh rate. Uncapped frame rates with upscaling active can cause frame pacing inconsistencies that feel like stutter.
❓ Frequently Asked Questions
Can I use DLSS on an AMD GPU in Fortnite? No. DLSS is exclusive to NVIDIA RTX GPUs (RTX 2000 series and newer). AMD GPU owners should use FSR 2, which is an excellent alternative and runs on any GPU.
Does Frame Generation help or hurt in competitive Fortnite? Frame Generation increases displayed frame rate but adds a small amount of latency (typically 10–15ms). For casual and ranked play below Champion League, the frame rate increase generally outweighs the latency cost. For professional or LAN-level competitive play, disable Frame Generation and rely on native DLSS rendering for the lowest possible input latency.
Which looks better on a 1080p 144Hz monitor - DLSS Quality or FSR 2 Quality? DLSS Quality is perceptibly sharper on a 1080p 144Hz display, particularly on Fortnite's foliage and distant structures. FSR 2 Quality is close enough that the difference is minor in motion. If you have an NVIDIA RTX GPU, choose DLSS Quality. If you have an AMD GPU, FSR 2 Quality is the right choice and performs well.
