Best Fortnite settings for FPS and input lag (2026)

Fortnite changed more under the hood in the last year than in the five before it. DirectX 11 is gone, the old Performance mode is gone, and the new one is quick enough that on a decent graphics card the processor sets the limit. Guides written before that tell you to lower things that no longer matter.

This one is for the game as it is now. Where the evidence is thin, we say so.

The short version

Performance mode, Fullscreen, Reflex On + Boost, View Distance near, the rest low, and nothing that touches Easy Anti-Cheat.

Rendering Mode: Performance. Window Mode: Fullscreen. VSync: Off. NVIDIA Reflex: On + Boost. View Distance: Near. Textures and Meshes: Low. 3D Resolution: 100 per cent, lowered only if the graphics card is your limit. Auto-Set Quality: do not use it.

Leave the shader cache alone, do not edit the game’s files, and do not switch off Secure Boot or TPM: since February 2026 every PC tournament requires them, together with IOMMU.

What changed in 2025 and 2026

DirectX 11 is gone, Legacy Performance mode is gone, and Performance mode got faster.

Version 37.00 (August 2025) replaced the old Performance mode with one built on DirectX 12. Version 40.10 (April 2026) removed the DirectX 11 option altogether, and in May 2026 the old Legacy Performance mode went too. Today the Rendering Mode menu has exactly two choices: Performance and DirectX 12.

Version 42.00 (August 2026) improved shader precaching in Performance mode, so budget PCs hitch less, and cut the processor cost of keyboard input. Version 42.30 (1 October 2026) spread Performance mode’s rendering work across more processor cores on some hardware.

Fortnite also ships DLSS 4 natively since spring 2026, without frame generation. NVIDIA Reflex 2 Frame Warp has not reached the game.

Performance mode or DirectX 12?

Performance mode for competitive play. DirectX 12 only for looks, or if Performance mode misbehaves on your PC.

Performance mode turns off most of the expensive rendering. On a current mid-range or better graphics card it is limited by the processor, not the card: in a 2026 test both an RTX 5070 Ti and an RX 9070 XT went past 720 FPS at 1440p, and the reviewers put the ceiling down to the processor. That changes which settings matter. In Performance mode, lowering resolution or textures barely moves the frame rate; the processor, the memory and View Distance do.

DirectX 12 is where Nanite, Lumen, virtual shadows and ray tracing live, and with any of them on, the graphics card becomes the limit. It is the mode for screenshots, not for ranked.

Both modes compile shaders. A Battle Royale match builds around 30,000 of them, and a new driver empties the cache, so the first match after a driver update loads longer and can stutter. That is expected and passes.

Every video setting, and what it costs

Names as in the current English menu. Several exist only in DirectX 12.

Fortnite video settings
Setting	Set it to	Why	What it costs
Window Mode	Fullscreen	Epic: the lowest input lag.	Slower Alt+Tab.
Resolution	Your monitor’s native	Lower only helps when the graphics card is the limit.	Nothing at native.
VSync	Off	It adds input lag. With G-SYNC, use the driver instead (next section).	Tearing without variable refresh.
Frame Rate Limit	Unlimited without G-SYNC or FreeSync	The lowest latency. The lobby is capped at 60 or 120, so judge it in a match.	Heat and power.
Rendering Mode	Performance	The lightest load on processor and graphics card.	Plainer image.
Auto-Set Quality	Do not use	It picks TSR and may switch on lighting effects.	Nothing.
3D Resolution	100%, lower in steps of 10 only if the graphics card is the limit	Keeps the image sharp.	Blurrier when lowered.
View Distance	Near	Players stay visible; only scenery fades in later.	Scenery pop-in.
Textures	Low	Frees video memory. In Performance mode, also untick High Resolution Textures in the launcher: it saves over 14 GB of disk.	Softer surfaces.
Meshes (Performance mode)	Low	Less object detail to process.	Less detail.
Shadows	Off	No competitive value.	Flatter image.
Global Illumination, Reflections (DirectX 12)	Off	Lumen options, heavy on the graphics card.	Flatter lighting.
Nanite Virtualized Geometry (DirectX 12)	Off	A large graphics card cost.	Less geometry detail.
Hardware Ray Tracing (DirectX 12)	Off	Needs Nanite and Lumen, and costs the most.	None of the ray-traced effects.
Anti-Aliasing & Super Resolution (DirectX 12)	Off, or DLSS or TSR if the graphics card is the limit	Options: TSR, DLSS, XeSS, FXAA, SMAA, TAA. FSR is not available in Fortnite.	Upscaling softens the image a little.
Effects, Post Processing	Low	Fewer particles in fights.	Plainer explosions.
Motion Blur	Off	Blurs exactly what you are trying to track.	Nothing.
NVIDIA Reflex Low Latency	On + Boost, or On if heat matters	NVIDIA measured up to 46 per cent lower PC latency on RTX 40 cards.	Boost: more power and heat.
GPU Crash Debugging	Off	Diagnostic tooling with its own overhead. Turn on only if Epic support asks.	Nothing.
Show FPS	On	You cannot tune what you cannot see.	Nothing.

Reflex, G-SYNC, frame caps and AMD

Reflex replaces the driver’s low-latency setting, and AMD users rely on the driver.

Lowest latency, or no G-SYNC: VSync off, Frame Rate Limit unlimited, Reflex On + Boost. You will see tearing.

With G-SYNC: G-SYNC on and Vertical sync on in the NVIDIA App or Control Panel, VSync off in the game, Reflex on. Reflex then caps the frame rate just under your refresh rate by itself, about 138 FPS at 144 Hz and 224 at 240 Hz. Without Reflex, cap at least 3 frames under the refresh rate. The game’s own limiter adds no delay in Blur Busters’ tests; outside limiters can add up to a frame.

Epic’s help page still lists Low Latency Mode Ultra in the NVIDIA Control Panel. With Reflex on it does nothing, because Reflex overrides it. Keep the driver’s shader cache on: it is what spares you the compile time.

On AMD: Anti-Lag 2 is not available in Fortnite. AMD’s own list of supported games does not include it, and the feature needs the developer to build it in. The driver’s regular Radeon Anti-Lag does work in DirectX 12, but AMD says it helps most when the graphics card is the limit, which Performance mode rarely is. Turn Radeon Chill and Radeon Boost off: one throttles the frame rate, the other lowers the resolution while you move.

The Windows side

Game Mode helps the low frames. Several famous switches do nothing for a DirectX 12 game.

Windows settings for Fortnite
Windows setting	Our advice	Evidence
Game Mode	On, the default	Stops driver installs and restart prompts during play. A 2026 month-long test found the 1% low frame rate rose with it on, while averages barely moved.
Hardware-accelerated GPU scheduling	Leave it at the default	Microsoft: you should not notice a change. It matters for frame generation, which Fortnite does not have.
Optimizations for windowed games	Does nothing here	It applies to DirectX 10 and 11 games. Fortnite is DirectX 12 only now.
Disable fullscreen optimizations	Do not bother	Microsoft’s data shows modern presentation is as good as or better than exclusive fullscreen.
Power plan	Balanced on two-die Ryzen X3D, otherwise your choice	Two-die X3D processors need Balanced and Game Bar to keep the game on the cache cores.
Memory Integrity	On, unless you measured a gain	Costs up to about 5 per cent, more in processor-bound games, in 2023 tests that did not include Fortnite. It is a security layer, so do not trade it for a number you have not seen.

Easy Anti-Cheat and what not to touch

Secure Boot, TPM, IOMMU and the game’s files stay as they are.

Fortnite runs Easy Anti-Cheat. Since February 2025 higher-level tournaments have required TPM 2.0 and Secure Boot on PC, and since February 2026 every PC tournament requires Secure Boot, TPM and IOMMU. A guide that tells you to switch any of them off is costing you tournaments, not gaining you frames.

The same goes for the game’s files. Making the settings file read-only, swapping the DLSS library or editing anything in the install folder means modifying an anti-cheat-protected game, and the gains, where there are any, are not worth that risk.

Tweaks that do nothing, or worse

Removed options, stacked settings that do not stack, and file edits that break things.

"Make GameUserSettings.ini read-only." Epic warns this stops the game saving your rendering mode.

"Stretched resolution gives more FPS." It renders about a tenth fewer pixels, which only helps when the graphics card is the limit. In Performance mode on a modern card it usually is not.

"Set a custom frame limit in the settings file." Not documented by Epic. Let Reflex set the cap instead.

"Ultra Low Latency and Reflex together." They do not stack. Reflex overrides the driver setting.

"Force DirectX 11 or Legacy mode for better lows." Both were removed, and DirectX 11 had a known crash bug before it went.

"Swap in a newer DLSS file." Fortnite ships DLSS 4 itself now, and users reported swapped files made DLSS vanish from the menu.

"Clear the shader cache for smoother play." It does the opposite: the next matches stutter while the cache rebuilds. Epic’s support only suggests it for one specific bug.

How to check it worked

Measure in a match, not the lobby, and throw away the first run after an update.

Turn on Show FPS, and Net Debug Stats in the Game UI tab if you also want ping. Judge it in a match or a fixed Creative route, never in the lobby, which is capped at 60 or 120 FPS.

For real numbers, use Intel PresentMon or CapFrameX. Compare the 1% low frame rate, not only the average, and keep one definition of it between runs. Do three runs of one to two minutes each and discard the first one after a driver update or a patch: the shader cache is cold, and that run measures compiling, not playing.

What Prospira does for you

The Windows side, explained and undoable. The game’s own files are never touched.

The menu above takes five minutes. The Windows side is where people get lost, and that is the part the Prospira Tweaking Utility does: Game Mode, GPU scheduling, Game Bar, mouse acceleration and the power plan, each explained before it runs, most undone in one click, with a restore point made before the first change. It does not edit Fortnite’s files.

Two honest notes. The app’s windowed-games switch does nothing for Fortnite, because the game is DirectX 12 only. And the app can switch Memory Integrity off; for Fortnite that is a trade of security for a few per cent, so do it only if you have measured the gain on your own PC.
