Sometimes when you use DaVinci Resolve to process the images’ color grading, effects, etc, you will encounter a problem where the software kind of not effectively using the GPU, and it’s often with free version. In this article, we will try to give you a solution we have discovered to how to troubleshoot DaVinci Resolve not using GPU effectively.

DaVinci Resolve is a software that integrates all solutions for images processing, video editing, color correction, visual effects, motion graphics and audio post production. According to Black Magic, the software is for Windows, macOS and Linux, and can leverage the rendering performance using GPU.

There’s one thing you need to keep in mind when rendering DaVinci Resolve: the free version can use only one GPU, while the paid version (studio version) can use up to 8 GPUs, making it a choice when you want to export in 8K.

At iRender, there are many option to render DaVinci Resolve. You can rent package single GPU RTX 4090, or multi-GPUs from 2/4/6/8 x RTX 3090/4090s.

This is based on our experience with some recent cases. Some people reported that they cannot render or the software crashes while they used the powerful RTX 4090. It could be due to many reasons, and sometimes need a DaVinci Resolve technician to carefully check. However, there are some simple solutions we have discovered as below (for paid version):

• • • • You should go to the menu DaVinci Resolve > Preferences > System > Memory and GPU.
      • In the GPU configuration, for “GPU Processing Mode” and “GPU Selection“, uncheck Auto and select either Cuda (if you are using NVidia) or OpenCL (if you are using AMD Radeon).
      • Click Save

• • • • You should go to the menu  DaVinci Resolve > Preferences > System > Decode Options
      • There, you can select Decode H.264/H.265 using hardware acceleration, and check CUDA or AMD based on your own graphics card.
