Windows specific issues

VirtualBox + Hyper-V

Genymotion Desktop uses VirtualBox hypervisor on Windows by default.

This configuration does not work well with Hyper-V.

This configuration can crash and it can cause very low performance.

Disable Hyper-V completely when using Genymotion.

Please follow the instructions from How to disable Hyper-V in Windows?.

Intel UHD integrated GPU

Due to limited OpenGL support with Intel UHD drivers on Windows, Genymotion Desktop does not work well on computers.

This issue affects computers with Intel UHD integrated GPU on Windows.

This issue is especially common on laptops.

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

Laptops with discrete GPU

Many modern laptops and notebooks have integrated and dedicated GPUs.

Integrated and dedicated GPUs can include an NVIDIA/AMD high-profile discrete GPU.

Integrated and dedicated GPUs can also include an integrated Intel/AMD GPU.

If this configuration applies, force Windows to use the high-profile discrete GPU globally. Follow the instructions from How to fix issues on Windows with laptops using hybrid graphics (dual GPU)?.

Android 15 & 16

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

Use QEMU hypervisor instead.

See How to switch Hypervisor.

Linux / Mac Intel

Android 15 does not work well with VirtualBox hypervisor.

Use QEMU hypervisor instead.

See Genymotion Desktop on-line documentation.

Windows

Android 15 does not work well on Windows hosts for the moment.

The virtual device does not have enough resources

If none of the Windows specific issues worked, then the virtual device may not have enough resources.

Recent versions of Android can be demanding on hardware resources.

If the virtual device profile does not have enough resources (CPU, RAM), Android might not run comfortably. Poor performance and crashes can happen.

To avoid poor performance and crashes, 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, refer to the on-line documentation.
