Performance issue: the created document is very large

When editing documents containing large numbers of paths, anchor points, gradients, and transparency effects:

Steps:

1. Open a complex AI document
2. Select multiple objects
3. Move or scale objects

Actual result:

• Mouse input and visual response are not synchronized
• Object movement has noticeable delay
• Canvas refresh rate decreases

Expected result:

Object manipulation should remain responsive in real time.

Current impact:

• Reduced design efficiency
• Increased waiting time
• Interrupted creative workflow
• Delayed project delivery

Especially affects:

• Branding projects
• Packaging design
• Illustration work
• Advertising design
• Large print documents

• Improve Illustrator rendering architecture.

  Current:

  Editing one object may trigger full canvas recalculation.

  Improvement:

  Use incremental rendering to update only changed areas.

  Technology:

• Dirty Region Rendering
• Incremental Rendering
• GPU Accelerated Rendering

• Expand GPU acceleration for:

• Path rendering
• Stroke preview
• Transparency calculation
• Live effects preview

• Goal:

  Reduce CPU workload and improve real-time interaction.

• Some operations still rely heavily on the main thread.

  Recommended separation:

• Rendering thread
• File loading thread

• Better utilization of modern multi-core CPUs.

• Effect calculation thread
• Preview generation thread
•  

• Implement:

• Object cache
• Preview cache
• Effect cache

• Avoid repeated calculations.

  Example:

  Moving an object should not require recalculating all effects

• We hope Adobe Illustrator can maintain its professional vector capabilities while adopting a more modern performance architecture.

  The goal is to provide designers with:

• Smoother object manipulation
• More stable zooming

• Performance should become a core part of the Illustrator experience.

•  
• Faster previews
• An uninterrupted creative workflow
