What NOVA changes for Fortnite, why the old launch options aren't worth it any more, and how to measure the difference on your own PC.
No FPS promise here: what Fortnite gains depends on how your PC is set up today. NOVA shows what's holding it back, then measures before and after.
01What NOVA changes for Fortnite
These are in Tweaks, off until you switch them on. Each edits Fortnite's own settings file, only while the game is closed: the same change as its video menu, made for you. Your current value is backed up first; switch it off and it goes back.
in-game V-Sync off
B · Measured by one lab or tester
Turns off V-Sync in the game's own settings, which holds each frame until the next refresh and adds input lag. With G-SYNC, use NVIDIA's G-SYNC setup instead of in-game V-Sync. Close the game first.
Exactly what it changesIn %LOCALAPPDATA%\FortniteGame\Saved\Config\WindowsClient\GameUserSettings.ini, changes every existing bUseVSync= line to bUseVSync=False (no line is added if it's missing). Nothing is changed while FortniteClient-Win64-Shipping.exe is running.
Plus everything that isn't game-specific: Windows, power, network and input settings, and Game Boost, which applies per-game settings each time Fortnite runs and puts the PC back when you close it. Every tweak →
02Launch options, rated
Guides still pass these around. NOVA's Games page shows the same verdicts for Fortnite: Use, Your choice, Test (prove it on your PC) or Skip.
Option
Verdict
Why
-USEALLAVAILABLECORES
Skip
From older guides. Unreal Engine already uses the cores it needs; no measured gain.
-NOTEXTURESTREAMING
Skip
Loads textures up front instead of streaming them, which needs much more video memory. No measured gain.
-high
Test
Starts the game at High CPU priority, the same as NOVA's per-game option. No lab has measured a gain; prove it on your PC before keeping it.
03Measure it on your PC
Benchmark › Proof mode runs the same test before and after a change and tells you whether the difference is real or within the noise, including when it made none.
The in-game overlay shows FPS and frame time in a corner of Fortnite, drawn in its own window, without touching the game.
History lists every change NOVA made, with undo for each, or Revert all.
