It typically takes only a few minutes to run the Brush Accelerator. Before running the test, you should save and close all open documents.
During the test, it’s recommended to close all unnecessary applications. Interacting with other applications while the Brush Accelerator is running can affect the test results. The test may take several minutes.
Some variance in your score should be expected. If you get a lower score than anticipated, simply wait until your system is less busy and then run the test again.
If your report scores are low, you can still run Painter. For the best experience, try using the Fast and Simple or Fast and Ornate brush categories, and working on smaller documents.
You can also run the Brush Accelerator from the Performance page of the Preferences dialog box (for more information, see Performance preferences), the Performance panel (for more information, see Performance controls), and the Advanced Brush Controls panel.
