Many users immediately assume they need a new workstation. While hardware certainly matters, performance problems are often caused by inefficient software settings rather than insufficient computing power.

In my experience working with SOLIDWORKS assemblies, drawings, and production models, optimizing a handful of Windows and SOLIDWORKS settings can noticeably improve responsiveness in less than 10 minutes.

This guide covers the most effective settings I use to maximize SOLIDWORKS performance without spending money on hardware upgrades.

Why SOLIDWORKS Feels Slow

Performance issues generally fall into one of two categories:

1. Hardware Limitations

Your workstation may not have enough resources for the size of your projects.

Common symptoms include:

• Frequent freezing when opening assemblies
• Slow drawing view generation
• Long rebuild times
• Simulation calculations taking excessively long

2. Software Configuration Issues

Many default settings prioritize visual quality and convenience rather than speed.

These features consume:

• CPU resources
• GPU resources
• Memory
• File loading time

The good news is that many of these settings can be adjusted.

Before You Change Any Settings

If your computer is more than five years old or has less than 16 GB of RAM, software optimization alone may provide limited improvements.

You should also verify:

• SOLIDWORKS is installed on an SSD
• Graphics drivers are up to date
• Windows is fully updated
• You are using a certified graphics card when possible

Many reported SOLIDWORKS performance problems stem from unsupported gaming GPUs and graphics driver issues. Community discussions frequently identify graphics settings and unsupported hardware as major causes of lag and instability.

Windows Performance Settings

1. Disable Visual Effects

Windows visual effects consume system resources that are better allocated to CAD applications.

Navigate to:

System Properties → Advanced → Performance Settings

Select:

Adjust for best performance

Benefits:

• Reduced UI overhead
• Faster screen updates
• Lower memory consumption

Recommended compromise:

Enable only:

• Smooth edges of screen fonts

This maintains readability while maximizing performance.

2. Enable Ultimate Performance Power Plan

Many workstations never operate at full CPU capability because Windows prioritizes energy efficiency.

Navigate to:

Settings → Power & Sleep → Additional Power Settings

Select:

Ultimate Performance

Benefits:

• Higher CPU utilization
• Faster rebuilds
• Improved assembly loading

For desktop workstations, this is usually the preferred option.

For battery-powered laptops, expect reduced battery life.

SOLIDWORKS System Options for Maximum Performance

Open:

Tools → Options → System Options

The following settings focus on minimizing unnecessary graphics processing and background calculations.

General

Disable:

• Show thumbnail graphics in Windows Explorer

Benefit:

• Reduces background file processing

Drawings

Enable:

• Automatically hide components when creating drawing views

Benefits:

• Faster drawing generation
• Reduced memory usage

Drawings → Performance

Disable:

• Display contents while dragging drawing views
• Automatically update drawing views when opening drawings

Benefits:

• Smoother drawing editing
• Faster file opening

Display

Disable:

• Dynamic Highlight from Graphics View

Set:

• Anti-Aliasing = None

Benefits:

• Reduced GPU workload
• Faster model interaction

Trade-off:

• Slightly rougher edge display

Performance

Recommended settings:

These settings reduce unnecessary calculations and memory consumption.

Enhanced Graphics Performance

SOLIDWORKS 2021 and newer include:

Enhanced Graphics Performance

Recommendation:

Enable it if:

• You use a certified workstation GPU
• Graphics performance is stable

Disable it if:

• You experience crashes
• Graphics artifacts appear
• Drawing performance becomes worse

This setting can significantly improve performance on some systems but may cause issues on others depending on hardware and drivers.

Assemblies

Enable:

• Large Assembly Mode
• Automatically load lightweight components

Disable:

• Update model graphics when saving files

Benefits:

• Faster assembly loading
• Lower memory consumption
• Improved performance with large projects

External References

Disable:

• Force referenced documents to save to current version

Benefit:

• Reduced save times

FeatureManager

Disable:

• Dynamic Highlight
• Preview Hidden Components

Benefits:

• Faster tree navigation
• Reduced UI lag

Messages, Errors, and Warnings

Disable:

• Display rebuild errors every rebuild

Benefit:

• Fewer interruptions during modeling

Document Property Settings

Document properties are stored inside each file.

Open:

Tools → Options → Document Properties

Navigate to:

Image Quality

Move both image quality sliders toward:

Low

Benefits:

• Smaller file sizes
• Faster opening
• Faster rebuilding
• Better assembly performance

Trade-off:

• Less visually smooth curved surfaces

Additional Performance Tips

Beyond settings optimization, consider:

Store Projects on SSDs

Large assemblies open significantly faster from SSD storage.

Close Unnecessary Applications

Web browsers, cloud sync tools, and communication software consume memory and CPU resources.

Use Lightweight Components

For large assemblies, lightweight loading often provides the biggest performance improvement.

Keep Graphics Drivers Updated

Certified workstation drivers generally provide more stable performance than gaming-oriented drivers.

Pros and Cons of Performance-Oriented Settings

Troubleshooting Common Performance Issues

Drawings Are Still Slow

Check:

• Automatic view updates
• Drawing image quality
• Hardware acceleration settings

Assemblies Take Too Long to Open

Check:

• Lightweight loading
• Large Assembly Mode
• SSD storage

Graphics Flickering

Try:

• Updating GPU drivers
• Disabling Enhanced Graphics Performance
• Verifying GPU certification

Rebuild Times Are Excessive

Review:

• Circular references
• Complex patterns
• Overdefined sketches
• Excessive in-context relationships

Frequently Asked Questions

How much faster can SOLIDWORKS become after optimization?

Results vary, but many users notice smoother navigation, faster drawing performance, and reduced assembly loading times immediately.

Will these settings affect model accuracy?

No. These settings primarily affect graphics quality and background processing, not geometric accuracy.

Should I disable anti-aliasing?

If performance is your top priority, yes. If visual quality matters more, keep it enabled.

Is more RAM always better?

For large assemblies, yes. Most professional users benefit from at least 32 GB of RAM.

Does a gaming GPU work well with SOLIDWORKS?

It can work, but certified workstation GPUs generally provide better stability and compatibility for professional CAD workloads.

Conclusion

When SOLIDWORKS becomes slow, many users immediately think they need a new workstation.

In reality, optimizing Windows settings, SOLIDWORKS System Options, and Document Properties often provides a noticeable performance boost in just a few minutes.

Start with:

1. Windows Performance Settings
2. SOLIDWORKS System Options
3. Document Property Optimization

Then test your workflow and adjust settings to find the best balance between performance and visual quality for your specific projects.

The fastest SOLIDWORKS configuration is not necessarily the best one—it is the configuration that helps you work efficiently without sacrificing the features you actually need.
