The Brush Accelerator predicts that your brush performance will be exceptional.
1000-4000 (orange)
The Brush Accelerator predicts that your system will have good performance; however, some especially large or complex brushes may benefit from system upgrades.
999 or lower (red)
The Brush Accelerator predicts that although Painter will run on this system, your brush performance will benefit from system upgrades.
Brush Accelerator - "x faster"
A calculation of your brush performance based on the combination of a baseline system, CPU features, and GPU.
Baseline
The Brush Accelerator begins by determining a baseline system, which is a theoretical, single-core processor with no enhancements.
Baseline + CPU
The Brush Accelerator compares the degree to which your brush performance is improved with the help of CPU features, such as multi-core, and extensions, such as AVX2 or NEON.
Baseline + CPU + GPU
The Brush Accelerator determines potential brush performance improvements from your GPU. A score will show only if your GPU accelerates brushing.
Processor (CPU) cores warning (red)
Processor (CPU) cores warning (red) - Your system does not have the recommended number or cores. You will want a minimum of four physical cores for your computer to keep up the pace. If possible, get the best quality cores, such as a a modern Intel or Apple CPU.
Extensions (CPU) warning (red)
Your system does not have a CPU with AVX2 or NEON. Systems that have an AVX2-compatible CPU (from Intel) or Apple CPU (with NEON) deliver enhanced performance.
Graphics processor (GPU) is gray
The Brush Accelerator has compared the speed of your CPU to the speed of your GPU and determined that your GPU does not accelerate brushing. If your score is below 1000, consider updating your GPU for better performance.
Graphics processor (GPU) is red
The Brush Accelerator is unable to compare the speed of your CPU to the speed of your GPU due to a compatibility issue. Consider updating your drivers to ensure OpenCL (1.2 or higher) compliance and run the test again. You will experience faster workflow with a more powerful GPU.
Memory warning (red)
Your system does not have the recommended level of RAM. The more RAM, the better for working with large documents with many layers. For fastest performance, you will need at least 8 GB RAM.
