Methods: Check and Adjust Brush Settings
Step-by-Step Instructions
-
Check Brush Settings in Tool Options Docker
- Open the Tool Options docker in Krita. If you don't see it, go to Settings > Dockers > Tool Options.
- Check your brush settings. If 'weighted' or 'stabilizer' is selected, this can cause a lagging effect. Change to 'basic' to resolve this.

Methods: Change Krita Renderer
Step-by-Step Instructions
-
Access Krita's Display Settings
- Go to Settings > Configure Krita > Display tab.

Change the Renderer
- Change your renderer (OpenGL or Direct3D). If using Windows, Direct3D is generally better, but switch to the other option if lagging persists.
Change the Renderer -
Restart Krita
- Restart Krita after changing the renderer.

Methods: Increase Krita Memory Limit
Step-by-Step Instructions
-
Increase Krita Memory Limit
- Go to the Performance tab in Krita's settings.
- Increase the memory limit, but leave at least 2-3 GB free for your system. The amount you can increase depends on your total RAM; don't exceed 75% of your total RAM.
Increase Krita Memory Limit
Tips
- If you have 16GB RAM, don't go above 12GB for Krita. If you have 8GB RAM, don't go above 7GB.
Methods: Lower Bit Depth for Color Space
Step-by-Step Instructions
-
Access Color Space Settings
- Go to Image > Convert Image Color Space.
Access Color Space Settings -
Lower Bit Depth
- Change your bit depth from 16-bit integer or 32-bit to 16-bit float (recommended). If already using 16-bit float, try 8-bit.
Lower Bit Depth
Tips
- Changing the bit depth may slightly alter your artwork's colors.
Common Mistakes to Avoid
1. Using Too Many Brush Settings
Reason: Complex brush settings with many active features (like texture, shape dynamics, scattering) can overload the system, causing lag.
Solution: Simplify your brush settings by reducing the number of active features or using a simpler preset.
2. Working with Too Large of a Canvas Resolution or Too Many Layers
Reason: High-resolution canvases and numerous layers demand significant processing power, leading to slowdowns and lag, especially on older hardware.
Solution: Reduce canvas resolution or merge layers to decrease the processing load.
3. Insufficient RAM or Low System Resources
Reason: Krita, like any digital painting software, requires sufficient RAM and processing power to operate smoothly. Insufficient resources will directly translate to brush lag.
Solution: Close unnecessary applications, upgrade your RAM, or consider using a less demanding canvas size and resolution.
FAQs
My Krita brush is lagging even on a powerful computer. What could be the problem?
High resolution canvases and complex brush settings are the main culprits. Try reducing canvas size, simplifying your brush settings (less texture, fewer particles), and lowering the brush opacity and size. Consider using a less demanding brush engine if available.
I've tried everything, but my brush still lags. What else can I do?
Check your graphics driver for updates. Outdated drivers can significantly impact performance. Also, ensure Krita is the only demanding application running. Close unnecessary programs and browser tabs to free up system resources. Consider disabling hardware acceleration temporarily to see if that helps.
My brush lag is only noticeable when using certain brushes or features. Why?
Some brushes, especially those with heavy particle or texture effects, are more demanding than others. Experiment with different brushes to find smoother options. Features like brush stabilization can also impact performance; try disabling them to see if it improves speed. Consider if your brush utilizes the pressure sensitivity of your stylus which can cause lag on certain tablets.
