Objective:

Suppose you are experiencing issues with your computer prioritizing an integrated graphics card. In that case, you may need to configure a high-performance NVIDIA graphics card to be the default option for nTopology.

If pressing CTRL+H doesn't trigger a High-res rendering, if black images display after rendering, or if you experience any unexpected graphics issues, follow these steps to set the NVIDIA graphics card as the preferred graphics processor.

Applies to:

• nTopology
• Windows 10
• NVIDIA GPUs

Procedure:

Method 1: 

Change your default GPU to a high-performance graphics card:

1. Right-click anywhere on your desktop.
2. Click NVIDIA Control Panel.
3. On the left side, select Manage 3D Settings.
4. Select the Global Settings tab
5. Change the preferred graphics processor to "High-performance NVIDIA processor."

Alternatively, keep the default settings and configure nTopology to use the high-performance graphics card:

1. Right-click anywhere on your desktop.
2. Click NVIDIA Control Panel.
3. On the left side, select Manage 3D Settings.
4. Select the Program Settings tab.
5. Select ntop.exe from the list of programs.
6. Select the preferred graphics processor and choose "High-performance NVIDIA processor."

Method 2: This method will overwrite the NVIDIA settings. You may need to use this method if your GPU isn't being selected in nTopology

To change your graphical performance settings for nTopology

1. Launch the Settings App.
2. Browse to System > Display > (scroll down) > Graphics settings.
3. Browse for the nTop.exe file
4. Click nTopology in the list and select Options.
5. Choose your performance mode preference and press "Save".
