Make sure to set your power settings to performance mode when using Genymotion Desktop.
Also, some laptops have a discrete GPU (NVidia/AMD) combined with an integrated GPU (Intel). In this case, you may need to force Genymotion Desktop (player.exe) to run with the high-performance discrete GPU (usually AMD or Nvidia) instead of Intel low-performance IGP. For more details, see How to configure NVIDIA Optimus and AMD Switchable Graphics for high performance with Genymotion Desktop (Windows)?
- Windows 8/10: this may be caused by Hyper-V. Please refer to Genymotion Desktop and Hyper-V (Windows 8/8.1/10).
Check that your hardware and software meet Genymotion Desktop minimum requirements. Please refer to Genymotion Desktop Requirements.
If you are using developer tools, make sure that you set Genymotion Desktop to use the same SDK tools as your IDE. Please refer to Configuring ADB.
Virtual Device Android version and density have a huge impact on performance. If Genymotion Desktop is too slow on your computer, try a virtual device with a lower Android version and 320-XHDPI density. See Genymotion Desktop hardware requirements for more details.
