The Virtual device takes a very long time to boot and is very slow

Windows specific issues

VirtualBox + Hyper-V

This is the most common cause on Windows systems.

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 using Genymotion.

Please follow the instructions from the following article: How to disable Hyper-V in Windows?

Intel UHD integrated GPU

Due to limited OpenGL support with Windows Intel drivers for low-end iGPU, Genymotion Desktop does not work well on computers, especially laptops, with some Intel UHD integrated GPU on Windows.

For more information and possible solutions, please 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: an NVIDIA/AMD high-profile discrete GPU and an integrated Intel/AMD GPU.

If this is your case, you need to force Windows to use the high-profile discrete GPU globally. To do so, please follow the instructions from this article: How to fix issues on Windows with laptops using hybrid graphics (dual GPU)?

Android 15 & 16

Linux / Mac Intel

Android 15 and 16 do not work well with VirtualBox hypervisor. Make sure to use QEMU hypervisor instead - see Genymotion Desktop on-line documentation.

Windows

Android 15 and 16 do not work well on Windows hosts at this time.

The virtual device does not have enough resources

If none of the above worked, or if it does not apply in your case, then the problem may be that the virtual device does not have enough resources.

Recent versions of Android can be demanding on hardware resources: if the virtual device profile you choose does not have enough resources (CPU, RAM) to run Android comfortably, you will experience very poor performances and/or crashes.

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