Fortnite DLSS, FSR, and Frame Generation Best Settings
Published
On this page
Fortnite supports DLSS, FSR, and frame generation — but only in DirectX 12 mode, and Performance Mode disables all of them. That’s the catch nobody mentions: the DX11-based Performance Mode most competitive players run for max FPS has its own lightweight renderer with no upscaling path, so you pick one route or the other. This guide covers the best upscaling settings for the DX12 crowd and explains when Performance Mode beats DLSS outright.
The Fortnite rendering choice: Performance Mode vs DX12 + upscaling
Before touching DLSS, understand which renderer you’re on. In Settings → Graphics → Rendering Mode:
| Rendering mode | Upscaling support | Best for |
|---|---|---|
| Performance Mode (DX11 alt) | None — its own low-overhead path | ⭐ Max FPS + lowest input delay on most PCs |
| DirectX 12 | DLSS, FSR, XeSS, Frame Gen | Better visuals on a capable GPU at a target FPS |
| DirectX 11 | None | Fallback for stability issues |
For competitive play, Performance Mode usually beats DX12 + DLSS on both frame rate and responsiveness because it renders far less to begin with. Reach for DX12 + DLSS only if you have GPU headroom and prefer the cleaner DX12 image. Our best Fortnite settings guide walks through the full Performance Mode setup.
Best DLSS / FSR settings in Fortnite (DX12)
If you’re on DirectX 12, set upscaling in Settings → Graphics:
| Setting | Competitive recommendation |
|---|---|
| Upscaler | DLSS (RTX) / FSR (AMD) / XeSS (Intel Arc) |
| DLSS/FSR mode | Quality (Balanced if you need more FPS) |
| Frame Generation | Off for competitive; On only for casual creative |
| NVIDIA Reflex | On + Boost — always |
| Anti-aliasing | Handled by the upscaler; don’t stack extra |
Quality mode is the sweet spot: a real FPS gain with almost no clarity loss, so distant enemies stay sharp. Only drop to Balanced if Quality misses your monitor’s refresh rate.
Why to skip Frame Generation in competitive Fortnite
Frame Generation inserts AI-interpolated frames between real ones. The FPS counter climbs, but:
- Input latency goes up, not down — your aim and edits register a beat later.
- It needs a strong base FPS to look clean; below ~60 real FPS it smears.
- The extra smoothness can mask that your real responsiveness got worse.
For build fights, edit peeks, and box fights, real frames win. If you want the mechanism in detail, see frame generation input lag explained. Save Frame Generation for relaxed creative maps on a high-refresh display.
Pair upscaling with a proper FPS cap and Reflex
Whatever renderer you choose, two things finish the latency chain:
- NVIDIA Reflex On + Boost — one of the simplest latency cuts in the game.
- Cap your FPS just below your refresh rate so the GPU never saturates and adds a frame of lag — see how to cap your FPS correctly and the best FPS cap for low latency.

Frequently asked questions
Does Fortnite support DLSS and frame generation?
Yes, but only in DirectX 12 mode. Fortnite supports NVIDIA DLSS Super Resolution and DLSS Frame Generation, AMD FSR, and Intel XeSS when the renderer is set to DirectX 12 in Settings > Graphics. Performance Mode (the DX11-based alternative renderer that most competitive players use for max FPS) does not support any of these upscalers — it has its own lightweight rendering path instead. So you choose one path or the other, not both.
Should I use DLSS or Performance Mode in Fortnite for competitive play?
For pure FPS and lowest input delay on most PCs, Performance Mode wins — it strips rendering to the essentials and typically beats DX12 with DLSS on frames and responsiveness. Use DX12 + DLSS Quality only if you want better visuals on a capable GPU while still hitting your FPS target, or if Performance Mode's flat look bothers you. Competitive players chasing the highest, most stable frame rate should stay on Performance Mode.
Should I turn on frame generation in Fortnite?
Not for competitive play. Frame Generation raises the FPS counter but adds input latency and makes aim feel less immediate, which matters in build fights and edit peeks. It also needs a solid base frame rate to look right. Use it only for relaxed creative or cinematic play on a high-refresh monitor where responsiveness isn't the priority. Improve your real FPS first with lower settings or Performance Mode.
Which DLSS mode is best in Fortnite — Quality, Balanced, or Performance?
Start with DLSS Quality for the cleanest image with a solid FPS gain. Drop to Balanced only if Quality still misses your FPS target. Avoid DLSS Performance in a competitive shooter unless your GPU is genuinely struggling — aggressive upscaling softens distant players and makes them harder to spot at range, which costs you more than the extra frames are worth.
Does DLSS or frame generation reduce input lag in Fortnite?
DLSS Super Resolution can lower input lag indirectly by raising FPS, since higher frame rates shorten the time between your input and the next frame. Frame Generation does the opposite — it adds latency even though the FPS number climbs. Always enable NVIDIA Reflex (Settings > Graphics) with any upscaler, cap your FPS just below your refresh rate, and use Performance Mode if raw responsiveness is the goal.
