Davinci Resolve Unsupported GPU Processing Mode

A more recent problem in DaVinci Resolve 18 that many users have encountered is the "Unsupported GPU Processing Mode" error. This error signifies a miscommunication between the software and the computer's Graphics Processing Unit (GPU). The GPU, being a pivotal component in video editing and processing, needs to work in harmony with the software for optimal performance. When this error arises, it can hinder the smooth functioning of DaVinci Resolve, affecting tasks like rendering, playback, and real-time effects application. Addressing this issue promptly is crucial, not just for uninterrupted editing but also to ensure the quality and efficiency of your projects. In the sections that follow, we'll explore the root causes of this error and provide step-by-step solutions to rectify it, ensuring that you can continue to harness the full potential of DaVinci Resolve without any hiccups.

Checking GPU Compatibility with DaVinci Resolve

When working with DaVinci Resolve, it's crucial to ensure that your GPU (Graphics Processing Unit) is compatible with the software. The GPU is the heart of video processing, and DaVinci Resolve heavily relies on it. Think of the GPU as the engine of a car. If the engine isn't compatible or isn't functioning correctly, the car won't run smoothly.

How to Check GPU Compatibility:

  1. Locate System Requirements: First, you need to be aware of DaVinci Resolve's GPU requirements. For instance, your GPU should have at least 2 GB of VRAM. This is the memory your GPU uses, similar to how RAM is used by your computer.
  2. Checking VRAM: To check your GPU's VRAM:
  3. Press the “Windows key + R” on your keyboard.
  4. Type “dxdiag” and click on “OK.”
  5. Wait for the tool to load, then navigate to the “Display” tabs. Here, you'll find the “Display Memory (VRAM)” section, which will show your VRAM in megabytes. For instance, 4000 MB indicates 4 GB of VRAM.

All 3 Solutions Working In 2023:

If your GPU is compatible but you're still having problems, here are the three ways to troubleshoot:

Graphics Drivers Issues

Understanding the Issue:Your computer's graphics drivers act as the bridge between the software (DaVinci Resolve) and the hardware (your GPU). If there's a miscommunication or misunderstanding between the two, you'll face this error.


  1. Update or Reinstall Graphics Drivers:
  2. First, you need a tool called Display Driver Uninstaller (DDU). Think of this as a mechanic's tool to fine-tune your car's engine.
  3. Download DDU and unzip the file.
  4. Run the Display Driver Uninstaller.exe file and follow the on-screen instructions.
  5. Once done, visit your GPU manufacturer’s website (like NVIDIA or AMD) and download the latest drivers. Installing these is like giving your car a fresh batch of optimized fuel.

Environment Variables

Understanding the Issue:Sometimes, certain settings on your computer can hide or block DaVinci Resolve's access to the GPU's features. It's like having a safety lock on your car's engine that you forgot about.


  1. Adjusting Environment Variables:
  2. Click on the Start Menu and search for "environment variables."
  3. Open the "Edit the system environment variables" option.
  4. In the window that pops up, click on the "Environment Variables" button.
  5. Look for a variable named CUDA_VISIBLE_DEVICES. If you find it, either remove it or set its value to 0. This is akin to unlocking that safety lock on your car's engine.

Software Conflicts with AMD Adrenalin

Understanding the Issue:Certain software, like AMD Adrenalin, can sometimes conflict with DaVinci Resolve. Imagine this as having two drivers trying to control the car at the same time.


  1. Reinstall AMD Adrenalin:
  2. Navigate to your computer's control panel or settings and uninstall AMD Adrenalin.
  3. Once removed, download the latest version from AMD's official website and reinstall it. This process is like ensuring only one qualified driver is in control of the car.

Manually Setting GPU Processing Mode

Sometimes, DaVinci Resolve might get confused about which GPU feature to use. It's like a car being unsure of which gear to shift into.


  1. Set GPU Mode Manually:
  2. Open DaVinci Resolve.
  3. Navigate to the top-left corner and click on "DaVinci Resolve" and then "Preferences."
  4. In the window that appears, ensure you're in the "Memory and GPU" section.
  5. Here, you'll see an "Auto" checkbox next to GPU processing mode. Uncheck this.
  6. From the dropdown, if you have an NVIDIA card, select "CUDA." If not, choose "OpenCL."
  7. Click "Save" and restart DaVinci Resolve.
