Performance preferences

You can set various performance preferences to optimize Corel Painter. For example, you can change memory options such as the amount of RAM used by the application or specify the volume name (Mac OS) or drive (Windows) that you want to assign as a scratch disk.

To ensure the optimal performance of scratch disks, consider the following:

The performance preferences are described in the following table.

 

Performance preference
Description
Memory Usage
Changes the percentage of RAM memory used by Corel Painter, which is set to 80% by default. You can dedicate as much as 100% of the memory to Corel Painter. The lowest percentage you can choose is 5%.
Painter Memory Extender (Mac only)
Allows Corel Painter to detect and use your Mac system’s additional memory to improve speed and performance. To enable the Mac Memory Extender, your system must have more than 4 GB of available RAM and you must also allocate more than 4 GB of the available memory to Corel Painter (by adjusting the Memory Usage slider).
Multicore Usage
Allows you to specify the number of cores that you want Corel Painter to use. If you use all of the computer’s available cores, it may impact the performance of any applications that you have running in the background.
Scratch Drive
Allows you to specify the volume name (Mac OS) or drive (Windows) that has free memory to allow Corel Painter to perform an operation if your computer runs out of RAM.
Undo Levels
Allows you to undo and redo up to 256 levels of changes.
The number of Undo levels applies across all open documents. For example, if you set 5 undo levels and have two open documents, undoing three operations on the first document leaves you with only two undo operations on the second document.
In addition, setting multiple undo levels uses a significant amount of disk space. If you perform multiple operations on the entire image, the whole image must be saved for each undo.
Smooth objects when zooming
Applies smoothing to the current view to minimize pixelation when zooming.
Increase screen drawing speed when zoomed out
Increases the speed at which the screen is drawn when you are viewing an image at less than 100% magnification. Enabling this option may decrease accuracy.
