Your laptop is not using the dedicated GPU most often because the app is set to “Power saving” in Windows Graphics Settings, the GPU drivers are outdated or broken, the laptop is running on battery with a power-saving profile, or you configured the game launcher instead of the actual game file. In rarer cases, the dedicated GPU is disabled in Device Manager or BIOS, or Windows isn’t detecting it at all.

The good news is that almost every case can be fixed in a few minutes without opening the laptop. This guide walks through each cause in order, from the quickest checks to the deeper fixes. If you only need the basic switching steps, read our main guide on how to switch to dedicated GPU first.

How to Confirm the Laptop Isn’t Using the Dedicated GPU?

Before fixing anything, confirm the problem with Task Manager. Press Ctrl + Shift + Esc, open the Processes tab, right-click any column header, and enable GPU engine. Now launch your game or app. If its GPU engine column shows GPU 0 (usually your Intel UHD, Intel Iris Xe, or AMD Radeon integrated graphics) instead of GPU 1 (your NVIDIA GeForce or AMD Radeon RX card), the laptop really is using the wrong GPU.

Also check the Performance tab. If the dedicated GPU (GPU 1) isn’t listed at all, your problem is detection rather than switching. Jump to the section on the dedicated GPU not showing up below.

A quick symptom check helps too. Very low FPS in games that should run well, stuttering, error messages like “minimum GPU requirements not met,” or a game listing “Intel UHD Graphics” as its display adapter are all signs the dedicated GPU is being ignored.

Fix 1: Set the App to High Performance in Windows Graphics Settings

The most common fix is to tell Windows directly which GPU the app should use. Windows’ own setting overrides automatic detection and, on recent versions, usually overrides NVIDIA and AMD app settings too.

1. Open Settings > System > Display > Graphics.
2. Find your app, or click Add desktop app and browse to its .exe file.
3. Open the app’s GPU preference and select High performance.
4. Close and relaunch the app.

If the app was previously set to “Let Windows decide” or “Power saving,” this alone fixes the problem in most cases.

Fix 2: Set the Game’s Real .exe, Not the Launcher

Many people set Steam, Epic Games Launcher, Battle.net, or the Riot Client to High performance and wonder why nothing changed. Launchers start a separate game executable, and that executable has its own GPU preference.

To find the real file in Steam, right-click the game, choose Manage > Browse local files, and look for the main .exe (sometimes inside a “Binaries” or “Win64” subfolder). Add that file to Windows Graphics Settings with High performance. For Minecraft Java Edition, the file you need is javaw.exe inside the Minecraft runtime folder, not the launcher.

Also open the game’s video settings. Many titles have a Display adapter or Graphics device option. Make sure your NVIDIA or AMD GPU is selected there.

Fix 3: Plug In the Charger and Change the Power Mode

Laptops aggressively limit the dedicated GPU on battery to save power. Some models won’t use it at all, or will cap its performance heavily, until the charger is connected.

1. Plug in the original charger (a low-watt USB-C charger may not be enough on gaming laptops).
2. On Windows 11, go to Settings > System > Power & battery and set Power mode to Best performance.
3. Turn off Energy saver (Battery saver on older versions).
4. Open your manufacturer’s app (Armoury Crate, Lenovo Vantage, MSI Center, HP Omen Gaming Hub, Dell Alienware Command Center) and switch to a Performance or Turbo profile.

If your GPU starts working only when plugged in, this was your cause.

Fix 4: Update or Clean-Reinstall the GPU Drivers

Outdated or corrupted drivers are the second most common reason Optimus and AMD Switchable Graphics stop working. Update both drivers, because switching depends on the integrated and dedicated GPU drivers working together.

• NVIDIA: Download the latest driver from NVIDIA’s website or the NVIDIA app.
• AMD: Use AMD Software: Adrenalin Edition or AMD’s driver page.
• Intel integrated graphics: Use the Intel Driver & Support Assistant, or your laptop maker’s support page.

If updating doesn’t help, do a clean install. Download the new driver first, then use Display Driver Uninstaller (DDU) in Safe Mode to remove the old one completely, and install the fresh driver. Some laptops work best with the manufacturer’s customized driver from the support page, so try that if generic drivers cause issues. Our guide on how to update GPU drivers covers each method step by step.

Fix 5: Set the Preferred GPU in NVIDIA Control Panel

On NVIDIA laptops, a wrong setting in NVIDIA Control Panel can force apps onto the integrated GPU.

1. Right-click the desktop and open NVIDIA Control Panel.
2. Go to Manage 3D settings > Program Settings.
3. Select your app (or click Add) and set the preferred graphics processor to High-performance NVIDIA processor.
4. Click Apply.

If NVIDIA Control Panel is missing, install it from the Microsoft Store or reinstall the driver. A missing control panel is itself a sign of a broken driver setup.

Fix 6: Check AMD Switchable Graphics

On laptops with an AMD Radeon dedicated GPU, open AMD Software: Adrenalin Edition, go to Settings (gear icon) > System > Switchable Graphics, find your app, and set it to High Performance. If the app shows “Power Saving” or “Based on power source,” change it. On newer versions where this panel isn’t available, rely on Windows Graphics Settings instead.

Fix 7: Enable the Dedicated GPU in Device Manager

Sometimes the dedicated GPU is simply disabled.

1. Right-click the Start button and open Device Manager.
2. Expand Display adapters.
3. If your NVIDIA or AMD GPU has a small down-arrow icon, right-click it and select Enable device.
4. If it shows a yellow warning icon, right-click and choose Properties to read the error code. Code 43 and Code 31 usually point to driver problems, so return to Fix 4.

Fix 8: Check the GPU Mode or MUX Switch Setting

Many gaming laptops have a GPU mode setting in the manufacturer’s app. If it’s set to an “Eco” or integrated-only mode, the dedicated GPU is turned off completely and no Windows setting will wake it.

• ASUS: In Armoury Crate, set GPU Mode to Standard (automatic) or Ultimate (dGPU only). Eco disables the dedicated GPU.
• Lenovo Legion: In Lenovo Vantage or Legion Space, check Hybrid Mode and any GPU working mode options.
• MSI: In MSI Center, check the GPU switch setting and avoid Integrated Graphics Mode when gaming.

A restart is usually required after changing the mode. Read our explainer on what a MUX switch is to understand which mode suits you.

Fix 9: Check BIOS Graphics Settings

Some laptops let you control the graphics mode from BIOS/UEFI. Restart and press the BIOS key (often F2, F10, Del, or Esc), then look under Advanced, Configuration, or Graphics for options like Graphics Device, Display Mode, or Hybrid Graphics. Make sure the dedicated GPU isn’t disabled and that the mode is Hybrid, Switchable, or Discrete.

Be careful here. On laptops where the internal screen is wired to the integrated GPU, disabling the iGPU can cause a black screen. Note the original setting before changing anything, and use Load Optimized Defaults if something goes wrong.

Fix 10: Check Which Port Your External Monitor Uses

If you play on an external monitor, the port matters. On many gaming laptops, the HDMI or a specific USB-C/DisplayPort output is wired directly to the dedicated GPU, while other ports go through the integrated GPU. Plugging into the “wrong” port can route output through the iGPU and lower performance. Check your laptop’s manual or spec sheet to find which port connects to the dedicated GPU.

Fix 11: Update Windows and the BIOS

Windows updates sometimes fix GPU switching bugs, and BIOS updates from your laptop maker often improve Optimus and Advanced Optimus behavior. Install pending updates from Settings > Windows Update, then check your manufacturer’s support page for a BIOS update. Follow the maker’s instructions exactly and keep the charger connected during a BIOS update.

Fix 12: Check Temperatures and Throttling

Sometimes the dedicated GPU is technically in use but performs so poorly that it looks like it isn’t. Heavy thermal throttling can drop clock speeds sharply. Monitor temperatures with the NVIDIA app overlay, AMD Software overlay, or HWiNFO while gaming. If temperatures are very high, clean the vents, raise the back of the laptop, and consider a cooling pad. Compare your readings with our guide to normal GPU temperature. If usage is stuck at 100% even when idle, see our guide on high GPU usage.

Why Is the Dedicated GPU Not Showing in Device Manager?

If the dedicated GPU doesn’t appear under Display adapters at all, Windows isn’t detecting it. Common causes include a GPU mode set to Eco or integrated-only, the GPU disabled in BIOS, a missing chipset driver, a failed Windows update, or, less often, a hardware fault.

Try these steps in order: switch the GPU mode back to Standard/Hybrid in the manufacturer’s app, check BIOS, click Action > Scan for hardware changes in Device Manager, enable View > Show hidden devices, install the latest chipset driver from your laptop maker, and then reinstall the GPU driver. If it still doesn’t appear after a BIOS reset and driver reinstall, contact the manufacturer, as it may be a hardware issue. Our dedicated GPU not detected guide goes deeper into this case.

Is It Normal for a Laptop to Use the Integrated GPU?

Yes. Using the integrated GPU for normal tasks is completely normal and intended. Laptops use NVIDIA Optimus or AMD Switchable Graphics to keep the dedicated GPU asleep during browsing, office work, and video playback, which saves battery and reduces heat. Seeing “GPU 0” for Chrome or Word is not a problem.

It only becomes a problem when demanding apps, like games, video editors, Blender, or AI tools, also run on the integrated GPU. That’s when you should apply the fixes above. To understand the difference between the two, see integrated vs discrete graphics.

Can Shared GPU Memory Cause This Problem?

Not directly, but it can confuse diagnosis. Task Manager shows Shared GPU memory for both GPUs, and a large shared memory number may make it look like the integrated GPU is doing heavy work. What matters is the Dedicated GPU memory usage and the GPU engine column. Our article on shared GPU memory explains this in detail.

Should You Use an External GPU Instead?

If your laptop has no dedicated GPU, or the built-in one has failed, an external GPU enclosure connected through Thunderbolt or USB4 is an option. It’s expensive and loses some performance through the connection, but it can turn a thin laptop into a capable gaming or rendering machine. See our guide on external GPU for laptop to check compatibility.

FAQs

Why does my laptop use the dedicated GPU only when plugged in?

Many laptops restrict the dedicated GPU on battery to protect battery life. Plug in the charger, set Windows power mode to Best performance, and choose a performance profile in your manufacturer’s app.

Why did my game stop using the dedicated GPU after a Windows update?

Windows updates can reset GPU preferences or install a generic driver. Reapply the High performance setting in Windows Graphics Settings and reinstall the latest NVIDIA or AMD driver.

Can I force all apps to use the dedicated GPU?

On NVIDIA laptops, setting Global Settings > Preferred graphics processor to the NVIDIA GPU makes most apps prefer it, and a MUX switch in dGPU-only mode routes everything through it. This reduces battery life significantly, so the per-app method is usually better.

Does the dedicated GPU have to show activity all the time?

No. It stays idle or fully powered down until a demanding app needs it. Zero activity during normal desktop use is expected.

Can a faulty dedicated GPU cause this?

Yes, though it’s rare. If the GPU doesn’t appear after BIOS reset, driver reinstall, and GPU mode checks, or it shows Code 43 repeatedly with clean drivers, a hardware fault is possible and you should contact the laptop manufacturer.
