Make X-Plane use your dedicated GPU on Windows, laptops, macOS or Linux, then verify the active card and fix common selection problems.
X-Plane has no in-simulator GPU selector. On Windows, close it, open Settings > System > Display > Graphics, add X-Plane’s executable, choose Options, select High performance, then relaunch. On a desktop, also connect the monitor to the dedicated NVIDIA or AMD card rather than the motherboard video output.
How do I force X-Plane to use the dedicated GPU in Windows?
Set a Windows per-application graphics preference for the actual X-Plane executable, not its installer, updater or desktop shortcut.
- Close X-Plane completely. Close the updater and any configuration utilities as well.
- Open Windows graphics settings. Go to
Settings > System > Display > Graphics. The exact wording differs slightly between Windows releases. - Add X-Plane. Choose the desktop-app option, select Browse, and locate X-Plane’s executable in its installation folder. Steam users must add the X-Plane executable from the simulator’s installation directory, not the Steam client.
- Select the dedicated card. Open the application’s Options, choose High performance, and check that Windows shows the expected NVIDIA or AMD GPU beneath that choice.
- Save and restart X-Plane. Load a flight before checking GPU activity; the menus alone place little demand on the graphics card.
A mistake we see constantly is adding the updater, installer or Plane Maker instead of X-Plane itself. Each executable has its own Windows graphics preference.
If the Windows option is unavailable or ignored, create a per-application profile in the NVIDIA or AMD graphics control panel and assign X-Plane to the high-performance adapter. Avoid changing the global GPU setting unless every application should use the dedicated card. On newer Windows configurations, the operating system’s graphics preference can take priority over the vendor control panel, so set both to the same adapter if necessary.
Does the monitor cable affect which GPU X-Plane uses?
On a desktop PC, every simulator display should normally be connected to a port on the dedicated graphics card. The motherboard’s HDMI or DisplayPort sockets are connected to the integrated GPU; the graphics-card sockets sit lower down on the expansion card.
Some systems can render on the dedicated GPU while sending the finished image through the integrated adapter, but this adds overhead and makes diagnosis confusing. If the card is not offered in Windows, check that it appears in Device Manager, that its driver is installed and that the firmware’s primary display setting favours PCIe or discrete graphics.
What should I change on a gaming laptop?
Connect mains power, disable battery-saving modes and select the laptop’s performance power profile. If the machine has a MUX switch or a manufacturer setting for discrete-only graphics, use it when maximum X-Plane performance matters, then restart as requested.
Do not disable the integrated GPU blindly on a laptop. Many internal displays are physically wired through it, even while the NVIDIA or AMD card renders X-Plane. Seeing both GPUs active is therefore normal; the renderer and 3D workload should be on the dedicated card.
How can I check which GPU X-Plane is using?
Use both X-Plane’s Log.txt file and Windows Task Manager to identify the active rendering device.
- Check Task Manager: run a flight, open Task Manager and display the GPU or GPU engine column for the X-Plane process. Match its GPU number to the named adapters on the Performance tab; GPU 0 is not always the integrated card.
- Check Log.txt: after launching X-Plane, open
Log.txtin the main X-Plane folder. The startup section identifies the graphics API, renderer and GPU model selected for that run. The file is replaced or refreshed on subsequent launches. - Check under load: use an external cockpit view or a detailed airport rather than judging activity from the main menu.
Low overall GPU usage does not prove that X-Plane selected the wrong card. The simulator may be limited by the CPU, a frame-rate cap, thermal throttling or one saturated rendering thread. Our advice on separating CPU and GPU bottlenecks in X-Plane 12 explains how to tell the difference.
Why is X-Plane still using integrated graphics?
The usual causes are an incorrect application profile, hybrid-laptop display routing, a power-saving mode or Windows failing to detect the dedicated card correctly.
| What you see | Likely cause | What to do |
|---|---|---|
Integrated GPU active, but Log.txt names NVIDIA or AMD | Normal hybrid-display composition | No change is needed if the dedicated card carries X-Plane’s 3D load. |
Log.txt names the integrated GPU | Wrong executable or conflicting profile | Remove the existing entry, add the real X-Plane executable again and align the Windows and vendor settings. |
| Dedicated GPU is absent from the high-performance option | Driver, power, firmware or hardware-detection problem | Confirm that Windows detects the card, connect laptop power and inspect the driver and firmware display settings. |
| Desktop performance remains poor after selection | Monitor connected to the motherboard or X-Plane is CPU-limited | Move the display cable to the graphics card and compare CPU and GPU frame times. |
| X-Plane crashes only after switching cards | Driver, Vulkan, plug-in or VRAM problem | Update the graphics driver, test without third-party plug-ins and lower texture demand. For a device-loss message, use our steps for correcting Vulkan device-loss errors. |
Reinstalling X-Plane rarely fixes adapter selection because Windows controls that choice. Reinstall only after confirming that the correct executable profile, driver and display connection are already in place.
Does X-Plane 11 or 12 need a different method?
X-Plane 11 and X-Plane 12 use the same operating-system GPU selection process, although their rendering back ends differ. X-Plane 12 uses Vulkan on Windows and Linux and Metal on macOS; X-Plane 11 installations may use Vulkan, Metal or the older OpenGL renderer.
Zink and anti-aliasing settings do not choose the graphics card. Once the dedicated GPU is confirmed, adjust resolution, texture quality, anti-aliasing, clouds and shadows gradually rather than setting everything to maximum; our graphics-setting guidance after switching GPUs covers those trade-offs.
How do I select the dedicated GPU on macOS or Linux?
macOS manages graphics selection itself, while Linux typically uses its PRIME offload configuration.
- Intel Macs with two GPUs: connect mains power and turn off Automatic graphics switching if that option exists on the model. X-Plane has no separate in-app override.
- Apple silicon Macs: there is one integrated Apple GPU using unified memory, so there is no second dedicated graphics card to select.
- Linux with NVIDIA PRIME: launch X-Plane through the distribution’s PRIME offload method. Where the helper is installed, Steam commonly accepts
prime-run %command%as a launch option. - Linux with Mesa graphics: systems offering PRIME render offload commonly accept
DRI_PRIME=1 %command%in Steam. Commands vary by distribution and driver, so confirm the selected renderer inLog.txt.
