Multi GPU Issues

Overview

When Enscape is executed by the CAD, Enscape is running in the same process as the CAD. This is currently limiting your options on setting specific driver profiles, since Enscape is using the same process as the CAD, the GPU driver is unable to distinguish between the two.

Therefore, 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, it can not be stressed enough that you need to make sure that the main display unit is connected to the GPU’s display port, and not to a display port associated with the motherboard. 

NVIDIA Graphics Cards

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

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’.

It can also be the case that Quadro cards do not have the option, under the Global Settings, to select the ‘Preferred graphics processor’ in which case you should:

  • Click on the Program Settings tab
  • Select your CAD from the Select a program to customize drop down
  • Set ‘Power management mode from Specify the settings for this program list to NVIDIA driver controlled.

Once that is done you should also go to the Global Settings section and set the Global Preset option to Workstation App – Dynamic Streaming.

This should result in better all round performance where Quadro cards are being used.

AMD Graphics Cards

AMD user have the possibility to use one of two Control Centers provided by AMD.

These are the Catalyst Control Center and the newer Adrenalin Control Centers.

Please refer to the appropriate article depending on which of these Control Centers you have installed on your machine.

AMD Catalyst Control Center

If you have the AMD Catalyst Center installed , then please follow these instructions to switch from your onboard graphics to AMD:

  • Right Click your Desktop
  • Select “AMD Radeon Settings”
Configuring an AMD GPU

Configuring an AMD GPU

  • 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.

AMD Adrenalin Control Center

The newer AMD Adrenalin Control Center no longer allows you to select the GPU. Instead, you have to make the selection via the Windows Graphics Settings dialog.

Open the Windows Graphics Settings dialog via Settings->System->Display->Graphics Settings.

Under the Choose an app to set preference, there is a drop-down menu where you will have two options to choose from. Theses two options will be either: Classic app / Universal app, or Desktop app / Microsoft Store app. Make sure to choose Classic app / Desktop app, depending on which of the two options you are provided.

Then click the Browse button, locate and add the CAD executable you are using Enscape with, which should be located somewhere on your C:/ drive. You will then be shown an Add button, click on that to which will add the CAD to the list where you will be provided two more buttons, Options and Remove.

Click Options, and then a Graphics preference dialog should appear with three options. One option being High performance, which is the one you should select. Then click Save.

You can then close the Graphics Settings window, and you should be able to use Enscape without any further issues.

NOTE: For Standalone Executable users, you will have to add the executable to the list in the Graphics Settings dialog. That executable file will be found in the %Temp folder in a folder with the name of that Standalone Executable. Once the Standalone executable has been added, you should be able to open it without issues. 

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.
