ReShade opens through its own launcher or by running the injector file you installed

ReShade is a tool that modifies how your game looks on screen — it can sharpen images, adjust colors, add effects, or change lighting. To use it, you need to start the ReShade injector before or during your game. The exact steps depend on whether you installed ReShade globally (for all games) or per-game (for one specific game).

If you installed ReShade globally, look for a file called ReShade.exe or ReShadeSetup.exe in your main ReShade folder. Double-click it to open the ReShade overlay menu. If you installed it for a single game, the injector file sits in that game's folder — find it and run it the same way. Once the overlay appears on screen, you can turn effects on and off, adjust settings, and save your preferences.

Key Takeaways

  • ReShade runs as a separate program that you launch before or during gameplay, not as a built-in game feature.
  • The injector file location depends on your installation type — global ReShade goes in your main ReShade folder, per-game ReShade goes in the game folder itself.
  • Once ReShade is running, press the Home key (or your configured hotkey) to open the overlay menu and toggle effects on and off.
  • Some games block ReShade or flag it as a cheat tool, so test it in your specific game before spending time configuring effects.

Finding the ReShade injector file on your computer

When you first installed ReShade, the setup asked you to choose a location. If you chose "global installation," ReShade created a folder somewhere on your computer — often in Program Files, your Documents folder, or wherever you told it to go. Open that folder and look for ReShade.exe or ReShadeSetup.exe.

If you installed ReShade for a specific game instead, navigate to that game's main folder (the one containing the game's .exe file). The ReShade injector should be there alongside the game executable. On Windows, you can right-click the game in Steam, select "Manage," then "Browse local files" to jump straight to the game folder.

Running ReShade before you start your game

The safest approach is to launch ReShade first, then start your game. Double-click the ReShade.exe file. A small window or overlay should appear — this is the ReShade menu. You will see a list of effects available and toggles to turn them on or off. Leave this window open, then launch your game normally through Steam, Epic Games, or however you usually start it.

Once your game loads, the ReShade overlay stays active. Press the Home key on your keyboard to show or hide the ReShade menu while playing. If Home does not work, check ReShade's settings — you may have set a different hotkey during installation, or the game may block that key. You can also press Shift + F2 in some configurations, or check the ReShade menu itself for the hotkey setting.

Injecting ReShade into a game that is already running

If your game is already open and ReShade is not active, you can still inject it mid-game. This works best with games that do not actively block ReShade. Run the ReShade.exe or injector file while the game window is in focus (click on the game first). ReShade will detect the running game and attempt to inject itself.

Some games will reject the injection or crash when you try this. If that happens, close the game completely, launch ReShade first, then start the game fresh. This two-step approach is more reliable and less likely to cause crashes or errors.

Enabling and disabling effects in the ReShade menu

Once ReShade is running and you can see the overlay menu, you will see a list of available effects — things like Sharpen, Bloom, Vibrance, Ambient Occlusion, and many others. Each effect has a checkbox or toggle next to it. Click the checkbox to turn an effect on or off. You can enable multiple effects at once, and they stack on top of each other.

Below each effect name, you will usually see sliders or number fields that let you adjust how strong the effect is. Move a slider to the left to weaken the effect, to the right to strengthen it. Changes happen in real time, so you can see the result when ready on your game screen. If you enable too many effects or make them too strong, your game may slow down — disable some effects or reduce their intensity if you notice frame rate drops.

Saving your ReShade settings so they load automatically

When you close ReShade or exit your game, your effect settings are saved to a file called ReShadePreset.ini (or a custom name you choose). The next time you launch ReShade with that game, those same effects and settings load automatically. You do not have to reconfigure them each time.

If you want to save multiple different looks for the same game, you can create separate preset files. In the ReShade menu, look for an option to "Save Preset" or "Save As." Give it a name like "Bright and Sharp" or "Dark and Moody," and ReShade stores it as a separate file. Later, you can load that preset by selecting it from the menu. This is useful if you want different settings for different games or different moods.

Troubleshooting when ReShade will not open or inject

If ReShade.exe does not launch or the overlay does not appear in your game, first check that you are running the correct file. Some games require you to run ReShade as Administrator — right-click ReShade.exe, select "Run as Administrator," and try again. This is especially common on Windows 10 and 11.

Second, verify that your game is not blocking ReShade. Many online games, competitive games, and games with anti-cheat systems (like Valorant, Fortnite, or Apex Legends) actively prevent ReShade from running. If your game blocks ReShade, there is no workaround — the game straightforward will not allow it. Check the game's community forums or ReShade's compatibility list to see if your specific game is known to block it.

Third, make sure you installed ReShade correctly in the first place. If you chose per-game installation, the injector file must be in the game folder, not somewhere else. If you chose global installation, the ReShade folder must still exist and contain the ReShade.exe file. If files are missing or moved, reinstall ReShade and choose the same installation method.

Frequently Asked Questions

What is the hotkey to open the ReShade menu while playing?

The default hotkey is the Home key. If that does not work, try Shift + F2. You can change the hotkey in the ReShade settings — look for a "Hotkey" or "Toggle Key" option in the menu itself. Some games block certain keys, so if neither default works, try a different key combination in the settings.

Will ReShade slow down my game or cause lag?

ReShade uses your graphics card to explore effects, so yes, it can reduce frame rate depending on how many effects you enable and how powerful your GPU is. Start with one or two effects and monitor your frame rate. If you notice stuttering or drops, disable some effects or reduce their intensity. You can always turn effects off during intense moments and back on during cutscenes.

Can I use ReShade in online multiplayer games?

It depends on the game. Single-player and cooperative games usually allow ReShade without issue. Competitive online games with anti-cheat systems (Valorant, Fortnite, Apex Legends, Call of Duty) actively block it and may ban you for trying. Check your game's terms of service or community forums before using ReShade online.

Do I need to reinstall ReShade for each game?

No, if you chose global installation during setup. One ReShade installation works with all your games. If you chose per-game installation, you need a separate ReShade folder in each game's directory. Global installation is simpler if you play multiple games.

What if ReShade crashes my game?

Try launching ReShade before starting the game instead of injecting mid-game. If crashes continue, disable all effects and enable them one at a time to find which effect causes the problem. Some effects conflict with certain games. You can also try running ReShade as Administrator or reinstalling it completely.
