Multi GPU Issues

Overview

If you have two GPUs in your system you have to make sure that Enscape uses the dedicated NVIDIA or AMD graphics card and not your onboard Intel integrated GPU.

Where two dedicated GPU’s are installed using SLi, Enscape should still function, although only one of the GPU’s will be utilized by Enscape at the present time.

NOTE: Where multiple display monitors are being used, make sure that the main display unit is connected to the GPU’s display port, and not to a display port from the motherboard. 

Mobile NVIDIA graphics card

  • Right Click your Desktop
  • Select “NVIDIA Control Panel”
Open NVIDIA Control Panel from your Desktop

The NVIDIA Control Panel will then open.

If you do not have the option to change the ‘Preferred graphics processor’ shown in the above screenshot, for example, where a laptop is being used in conjunction with a docking station, then scroll down in the list until you find ‘Power management mode’ where you can set that option to ‘Prefer maximum performance’.

Mobile AMD graphics card

Please follow these instructions to switch from your onboard graphics to AMD:

  • Right Click your Desktop
  • Select “AMD Radeon Settings”

  • The AMD Catalyst Control Center should have opened so you can take the following steps:
    • Select System
    • Select Switchable Graphics
    • Running Applications view will be displayed by default, or you can use the Browse or Search options to find the Enscape Application.
    • For Enscape select High Performance.

  • If the Switchable Graphics mode for an application has been changed, a User icon will appear next to the name of the application profile.  These user defined application profiles can be removed by selecting Delete from the drop-down list, as shown in the example above.

General Solution for Intel HD (Desktop + Mobile)

If the solutions above do not work for you, or you are working on a desktop machine, please follow these instructions to disable the Intel graphics card via the Windows Device Manager:

WARNING: On some systems, the following steps may be harmful and can only be reverted via Windows Safe-Mode.

  1. Pressing Windows + S will open the native Windows search function, perform a search for ‘Device Manager’
  2. Expand the Display adapters from the list displayed in the Device Manager.
  3. If you see an ‘Intel HD Graphics’ card listed, right click on it and choose Disable from the menu.

Your system will now automatically use the second GPU in your system. This solution does work for desktop and mobile machines. However, if you are using a notebook, you probably want to follow the instructions above, because disabling your Intel HD graphics card can increase your power consumption and therefore reduce your battery time.

Further Troubleshooting

NOTE:
If you find that there are options missing from the NVIDIA or AMD Control Panel shown in the above screenshots, this would indicate that the main display may not be plugged in to the display port of the NVIDIA / AMD GPU; meaning the main display is plugged in to the port connected with the integrated Intel graphics chip on the machine’s motherboard.

Check that your main display is plugged in to the port of the GPU and then reboot the machine. You should then find that the missing options will become available in the GPU’s Control Panel.
