To run R.Design stably, you need to verify that your PC is using the correct GPU (graphics processor) and configure it appropriately. Especially on laptops (Gaming Laptops), incorrect settings can cause the high-performance GPU not to be used, leading to crashes or performance degradation.

🚨

Important: Laptop PC users should perform both “Windows Settings” and “NVIDIA Settings” below. Doing only one may not be effective.

1. NVIDIA Control Panel Settings (Recommended)

This can force GPU allocation more powerfully than Windows default settings. If you have an NVIDIA GPU (GeForce RTX, etc.), be sure to configure this.

  1. Right-click on an empty area of the desktop and open “NVIDIA Control Panel”.
  2. Select “Manage 3D settings” from the left menu.
  3. Open the “Program Settings” tab.
  4. Add R.Design under “Select a program to customize.”
    • If it’s not in the list, use the “Add” button to specify R.Design’s .exe file.
  5. Under “Select the preferred graphics processor for this program,” select “High-performance NVIDIA processor”.
  6. Click “Apply” at the bottom right.

2. Force GPU Usage in Windows

Configuring Windows OS settings as well can ensure more reliable operation.

  1. Type “Graphics Settings” in the Windows search bar and open it.
  2. Check if R.Design is in the “Classic app” list.
    • If not, use the “Browse” button to add R.Design’s executable file (.exe).
  3. Click R.Design in the list and select “Options”.
  4. Select “High Performance” and save.
    • Confirm that a high-performance GPU name like NVIDIA GeForce RTX 3060 is displayed here.

3. Check VRAM in Task Manager

If the app is slow or crashes, VRAM (video memory) may be insufficient.

  1. While the app is running, press Ctrl + Shift + Esc to open Task Manager.
  2. Open the “Performance” tab and click “GPU 1” (or GPU 0) NVIDIA RTX, etc.
  3. Check the Dedicated GPU memory graph.
    • If this is maxed out (e.g., 6.0/6.0 GB), VRAM is insufficient.
    • When it starts using “Shared GPU memory,” operation becomes extremely heavy and eventually crashes.
⚠️

Signs of VRAM shortage:

  • Screen stutters or freezes
  • Textures become blurry
  • Forced termination with error DXGI_ERROR_DEVICE_HUNG

4. Driver Updates

Old GPU drivers are incompatible with the latest Unreal Engine features and can cause crashes.

ℹ️

Driver updates via Windows Update are often several months old, so always use the GPU manufacturer’s official tools.
