The recommended PC specifications for smooth operation of Cubism Editor are as follows. Please use this as a reference when running Cubism Editor on your PC or when making a purchase.

※ This information is based on Cubism Editor 5.3.00 beta1 (as of 2025/08/26).
※ The required CPU, GPU, and memory capacity depend on the image size, number of vertices, and number of parameters you input. The larger the image size and the more vertices and parameters you use, the higher the performance of the CPU and GPU, as well as the required memory capacity.
Additionally, the contents presented in this article do not guarantee the operation of Cubism Editor or any other software. Please adjust according to the scale of the models you create.

For basic operating environment requirements, please check the Cubism Editor system requirements page.

CPU

As the number of parameters, deformers, drawable objects (art meshes, art paths), and polygons increases, the required CPU performance also increases. A higher performance CPU is also required for comfortable UI operation.

When choosing a CPU, please select relatively new models and generations. Generally, choose one with a higher clock frequency, with more cores and threads.

GPU (Graphics Card)

As the model size (canvas size), number of polygons, and number of Blend Modes used increase, the required GPU performance also increases. Cubism Editor 5.3.00 beta1 recommends using OpenGL 4.5 or higher, so check for support of this version when selecting a GPU.

Choose relatively new models and generations, and select GPUs with higher clock frequencies and larger memory.

If you are using large PSD files without creating texture atlases, or if your model has many vertices, having a higher memory transfer performance may yield better results.

RAM (Memory Capacity)

If your model images are numerous or large, or if you are using sequential image output or video output, this will affect memory usage. Increasing the required memory capacity is also necessary for smooth UI operation. If you plan to use large PSD files, remember to allocate enough memory accordingly.

In addition to the above, if you plan to run another application alongside Cubism Editor, having 32GB of RAM is generally considered safe.
