Windows-specific issues

Intel UHD integrated GPU

Intel UHD integrated GPU has limited OpenGL support on Windows.

Genymotion Desktop does not work well on computers with Intel UHD integrated GPU on Windows.

For more information and possible solutions, refer to the article "The virtual device crashes, freezes or fails to boot on Windows."

Laptops with discrete GPU

Many modern laptops have both integrated and dedicated GPUs.

To use the high-profile discrete GPU globally on Windows, force Windows to use the discrete GPU.

If the case applies, follow the instructions from the article How to fix issues on Windows with laptops using hybrid graphics (dual GPU)?

VirtualBox + Hyper-V

Genymotion Desktop uses VirtualBox hypervisor on Windows by default.

This configuration does not work well with Hyper-V (crashes, very low performance).

It is therefore recommended to disable Hyper-V completely when running Genymotion Desktop.

Follow the instructions from the article Genymotion Desktop and Hyper-V (Windows).

Android 15 and 16

Android 15 and 16 do not work well with VirtualBox hypervisor.

Use the QEMU hypervisor instead.

See Genymotion Desktop online documentation for details.

Linux / Mac Intel

Android 15 does not work well with VirtualBox hypervisor on Linux / Mac Intel.

Use the QEMU hypervisor instead.

See Genymotion Desktop online documentation for details.

Windows

Android 15 does not work well on Windows hosts at this time.

The virtual device does not have enough resources

If previous troubleshooting steps fail, the virtual device may not have enough resources.

Recent versions of Android can be demanding on hardware resources.

If the virtual device profile selected does not have enough resources (CPU, RAM) to run Android comfortably, users experience very poor performance and/or crashes.

To avoid this, make sure the virtual device has the following hardware settings:

| Android version | Virtual CPUs | RAM | |---|---|---| | Android 14 and above | 4 | 4GB or 8GB (recommended) | | Android 10 - 13 | 2 or 4 (recommended) | 2GB or 4GB (recommended) | | Android 9.0 and below | 2 | 2GB or more |

For more information, please refer to the online documentation.
