Optimize Epic Games Launcher on Windows (to make it use less resources)

If you use Epic Games You may often notice that the Launcher is consuming more resources than expected or that downloads are slow. On many Windows computers, this causes CPU spikes, stutters in games, and even with fans running at full blast when you just wanted to open your library. Is it possible to optimize the Epic Games Launcher on Windows? The answer is yes. We explain it here.

We don't stay in generalities: you will see Launcher settings, solutions for speed up downloads, Fortnite-specific optimization (including tweaks to the GameUserSettings.ini file), recommended Windows tweaks, and, if you have NVIDIA, a tuned Control Panel profile. We also include the technical reasons why the client may be running so high on CPU and how to mitigate it with safe measures.

Why the Epic Games Launcher can slow down Windows

Understanding the origin helps you choose the right solution. The Epic client integrates web, store, and background service features that can increase consumption on specific equipmentThese are the most common factors that, together, explain the high CPU usage:

• Silent activity in the background: Automatically checks for and downloads updates to the Launcher itself and your library, even if you don't plan on playing at the time.
• Interface based on Chromium: The store and social elements render as a website with animations and videos, which adds CPU and RAM load.
• Library Scan and game integrity verification at startup or at intervals, which is more cumbersome on PCs with many titles or slow disks.
• UI Visual Effects: Transitions and background videos which can penalize if your GPU does not accelerate the interface well.
• Auto start and cloud sync: useful, but activating at unexpected times can generate usage spikes.
• Client optimization could be improved: the community agrees that, compared to other launchers, Epic still has room to improve. efficiency of resources.

Quick Launcher settings to reduce CPU usage and speed up downloads

If you're looking to optimize the Epic Games Launcher, start with the changes that offer the most impact with the least effort. Many users report noticeable improvements after apply these settings:

• Close the Launcher After starting a game: Start the game and then select Quit from the tray icon. The game will continue running, and you'll free up resources.
• Deactivate background downloads/updates: Launcher Settings → Launcher Preferences → Uncheck Allow background downloads and updates.
• Remove the automatic start: In Launcher Settings, uncheck Run at startup; or use Task Manager → Startup → disable Epic Games Launcher.
• Delete Launcher cache: close the Launcher (also from the tray) → Windows + R → %localappdata% → EpicGamesLauncher → Saved → delete “webcache”, “webcache_4147”, “webcache_4430” (or similar) and “Cache” → reopen the Launcher.
• disable the in-game overlay: Settings → Game Preferences → Uncheck Enable Epic Games Overlay. For some titles, you'll need to do this on a per-game basis (Library → three dots → Manage).

It is also useful to adjust the general preferences of the client to make it less intrusive. In Settings, it is recommended to keep the browsing in offline mode, enable Minimize to tray and enable Cloud save; however, disable Regulate downloads, Use proxy, Allow installations while editors are running, and notifications from free games/offers if they do not provide you with value (they reduce distractions and possible micro-cuts).

Useful commands to optimize Epic Games Launcher

If you feel like going faster, there are advanced flags that some users have found to be effective. Use them with caution, because they can change between updates:

• Epic Games Launcher (in the shortcut, Shortcut tab → Target, add at the end): -NoUpdateChecks (avoid checking for updates on startup), -SkipBuildPatchPrereq (omits certain prior checks), -OpenGL (experimental; force interface rendering with OpenGL on some machines).

Example of complete destination: «C:\Program Files (x86)\Epic Games\Launcher\Portal\Binaries\Win64\EpicGamesLauncher.exe» -NoUpdateChecks -SkipBuildPatchPrereq. Remember that these options may remain obsolete in future versions.

Executable Properties and DPI Scaling

Some computers experience improvements when the Fortnite executable is not affected by fullscreen optimizations or DPI scaling. Open the installation path (default C:\Program Files\Epic Games\Fortnite\FortniteGame\Binaries\Win64) and locate FortniteClient‑Win64‑Shipping:

1. Right click → Properties → Compatibility.
2. Brand Disable full screen optimizations.
3. Under “Change high DPI settings,” check “Override high DPI scaling behavior” (if present) and apply.

On some computers these boxes do not appear; it's okay, apply the ones you have and check if you notice minor stutter.

NVIDIA Control Panel: Recommended Profile

If you're using NVIDIA, fine-tuning your 3D profile helps a lot to stabilize frame times. This helps optimize Epic Games Launcher on Windows. How to do it? In the Control Panel, go to Adjust image settings with preview and check "Use advanced 3D image settings." Then go to Manage 3D settings and enter the following:

• image scaling: Disabled
• Ambient occlusion: Disabled
• Anisotropic filtering: Disabled
• Antialiasing – FXAA: Disabled
• Antialiasing – Gamma correction: Disabled
• Antialiasing – Mode: Disabled
• Max frame rate of app in background: Disabled
• CUDA – GPU: All
• DSR – Factors: Disabled
• Low latency mode: Enabled
• maximum frame rate: Disabled
• MFAA: Disabled
• OpenGL rendering GPU: Automatic selection
• Power management: Optimal power
• Preferred refresh rate: The highest available
• Shader cache size: Controller Default
• Texture Filtering – Anisotropic Sampling: Enabled
• Texture Filtering – Negative LOD Bias: Allow
• Texture Filtering – Quality: Performance
• Texture Filtering – Trilinear Optimization: Enabled
• Thread Optimization: Automatic
• Triple buffer: Disabled
• Vertical Sync: Disabled
• Pre-rendered VR frames: 1

Under Adjust desktop size and position, select Full Screen, perform GPU scaling and check the corresponding box below. Make sure to set the refresh rate to the highest value. On many monitors, this change alone reduces microstuttering.

Drivers, Visual C++ and basic maintenance

A solid foundation prevents additional problems. Keep your system up to date and eliminate software bottlenecks that cause disruption. Global CPU:

• Update the GPU drivers from NVIDIA, AMD or Intel.
• Install the redistributables of Microsoft Visual C ++ latest (x86 and x64): download them from the official website, install x86 first and then x64, and reboot when the rest of the changes are complete.
• Run antivirus/antimalware and apply Windows Update (performance improvements and patches usually arrive).

System hygiene tips in Windows: enable the Game Mode; disable the Xbox Game Bar if you're not using it; try Hardware-Accelerated GPU Scheduling (it may help or stutter, check it on your machine); clear temp files with Windows + R → %temp% → remove everything (it's safe). In Windows Performance Options, select "Adjust for best performance" and leave Smooth edges for fonts enabled.

Network and Latency: Ethernet and Adapter Options

More tips for optimizing Epic Games Launcher: If you're playing wired, fine-tune your adapter to maintain consistent connectivity. Open Device Manager (Windows + R → devmgmt.msc) → Network adapters → your Ethernet card (Realtek, Intel…):

• In Power Management, uncheck "Allow the computer to turn off this device to save energy.
• On the Advanced tab, set Speed ​​and Duplex to the highest supported value.
• Deactivate «Green Ethernet» and any energy-saving options that may cut performance.

This ensures that the network interface does not go to sleep and avoids latency spikes caused by traffic policies. aggressive savings.

Advanced measures: priority, affinity and warnings

If you're still having trouble and want to optimize Epic Games Launcher, you can still try advanced tweaks. Not all of them are recommended for everyday use, but you'll want to try them if you're dealing with recurring failures:

• Process priority: Open Task Manager (Ctrl + Shift + Esc) → Details tab → FortniteClient‑Win64‑Shipping.exe → Right click → Set priority → High. Test to see if it helps.
• Launcher CPU Affinity- In the same Details menu, EpicGamesLauncher.exe → Set Affinity → uncheck some cores. Only use this if the Launcher is blocking your computer; it may affect the stability.
• Avoid the overclock If you are not sure: it can shorten the lifespan of your components and does not always give stable results.
• Consider activating XMP in BIOS so that your RAM works at its nominal speed (make sure you check your specific motherboard/memory).

As a final step after a maintenance session and major changes, it is ideal to restart the pc so everything is clean and the system properly applies optimizations. Essential for optimizing Epic Games Launcher on Windows.

Useful notes and references

Epic has official instructions for improving the speed of Launcher downloads. You can find them in their help center: Epic documentationThis reference has been pointed out by users who, after trying everything, noticed a noticeable improvement.

A relevant note circulating in communities: an author indicated that he would prepare a update in early December 2024 due to changes in Chapter 6 that were causing errors on many PCs, and their guide was pinned high on the forums. These kinds of warnings reinforce the idea that, with major game updates, it's worth it. revisit settings and revalidate them.

Finally, if you have just installed a graphics card and notice serious problems in several games or your computer starts very slowly, you may be interested in a more extensive diagnostic check, from clean drivers to hardware checks. Sometimes what seems like a Launcher failure is a symptom of something else.

Epic Games Launcher's high CPU usage isn't always your PC's fault: its Chromium-based architecture, background activity, and the size of the store all play a role. By combining client tweaks, a sensible graphics profile, cache cleaning, and good system maintenance, you'll be able to optimize Epic Games Launcher on Windows without any problems.
