Adjusting GPU settings

---

After the test, Painter automatically enables your GPU if the Brush Accelerator determines that it may help with brush performance. If you have multiple available GPUs, check the Preferences dialog box to ensure that Painter has chosen the faster of the supported GPUs.

You can also change the selected GPU, run the Brush Accelerator again, and compare scores for each GPU. In addition, you can toggle GPU support for all brushes, and for individual brushes, which lets you conduct your own tests for responsiveness with your favorite brushes, settings, and workflows.

The actual performance you experience is dependent on your system hardware and several additional factors, such as the brush variants and brush settings you are using, and document complexity, including file size, canvas dimensions, number of layers, as well as use of selections and other elements.

To run the Brush Accelerator on a different GPU

After the test, if the selected GPU accelerates Painter, you will have a higher Brush Accelerator score, and the Use the graphics processor (GPU) to accelerate brush performance check box will be enabled in the Preferences dialog box.

If the Use the graphics processor (GPU) to accelerate brush performance check box is disabled, your system does not have a GPU that is compatible with the Brush Accelerator.

To disable GPU support for all brushes

To disable GPU support for the currently selected brush

You must first have a GPU enabled in the Preferences dialog box.

You can use the Painter Search bar to find brushes that can leverage specific performance technologies by choosing Window Search, and using the terms GPU or Multi-core. If you have a Mac or Windows computer that uses Intel processors, you can search using the term AVX2 to find brushes that leverage those extensions. If you have a Mac computer that uses an Apple CPU, you can search using the term NEON.
