If you are getting brush lag when the GPU is on, turn it off and apply a few brushstrokes to see if it helps. However, you can try turning it off and experiment to see if your GPU is indeed actually improving responsiveness in your own common workflows. On the other hand, if the GPU setting is indeed checked after the test, this means that Painter has determined that your GPU could help responsiveness. (The GPU setting is left unchecked when the GPU is supported by Painter, but the test determined that using it would not likely help performance.) If the Use the graphics processor (GPU) to accelerate brush performance check box is unchecked in your preferences after running the test, you can try turning it on to see if the GPU helps with brush responsiveness. This is where you may want to experiment to see how the GPU support is working for your hardware, your favorite brushes, and workflows.

The actual performance you may observe will depend on your system hardware (the CPU and GPU), the brush variant and brush settings you are using as well as the document complexity (document dimension, number of layers, use of a selection, etc.). In this example, the check box is checked, showing that Painter determined the GPU should be considered for computation. You can find this preference - Use the graphics processor (GPU) to accelerate brush performance - in the Performance section of the Preferences dialog. In addition to this report, at the end of the Brush Benchmark test, Painter will also automatically either enable or disable the performance preference to use or not use the system GPU. In this example, this is the report obtained: Once the benchmark is set, Painter will report some findings about your CPU and GPU as well as other information. To run the Brush Benchmark test, click the Optimize Now button in the Perfomance section of the Welcome screen. This test examines your system components and sets a performance benchmark. To use your system's GPU, Painter first needs to check the GPU for technology support and performance by using the Brush Benchmark test.

Other CPU-based performance enhancements were added to Painter 2020 as well, however this article focuses on the GPU support.

CorelDRAW Graphics Suite 2021 (Windows/Mac)Ĭorel Painter® 2020 introduces an exciting new technology that allows the digital art software to leverage the computing power of video cards (GPU) for increased responsiveness.
