How do I make SOLIDWORKS run faster?

How to improve the performance of SOLIDWORKS.

  1. Adjust the Windows Visual Effects settings (found in Performance Options) for optimal performance. …
  2. Set the SOLIDWORKS options optimally. …
  3. Turn off the unused SOLIDWORKS add-ins. …
  4. Increase processor clock speed.

Why is my SOLIDWORKS assembly so slow?

Why is large assembly performance an issue? If you have a large assembly, SOLIDWORKS will need to use most, or all, of your system’s resources, which will then slow down your system. The solution could be as simple as getting a slightly more powerful computer.

How do I give more RAM to SOLIDWORKS?

How to set custom sized virtual memory:

  1. System > Advanced System Settings > Advanced (Tab) > Settings..
  2. Advanced (Tab) > Change..
  3. Untick ‘automatically manage paging file size for all drives.
  4. Choose the Drive you would like to utilize Virtual Memory on. ( …
  5. Choose Custom size button.

Do configurations slow down solidworks?

Switching from one configuration to another can slow performance, especially in large assemblies, because the software is loading a different model. Switching from one display state to another can be faster because the model data is already loaded.

How do I enable OpenGL in Solidworks?

ables graphics rendering using only software. To enable Software OpenGL: Start SOLIDWORKS normally.

Before you open a document:

  1. Click Options (Standard toolbar) or Tools > Options.
  2. Select Performance.
  3. Select Use Software OpenGL.

Is 12 GB RAM enough for SOLIDWORKS?

While the exact amount of RAM you need is going to depend on your particular models, Solidworks generally needs between 4-8GB of RAM for tasks such as rotating models, simulations, and renders. Due to this, we recommend having 16GB in your system to give you plenty of free RAM for other programs you may have running.

Is more RAM better for SOLIDWORKS?

The researchers showed that invest- ing in an Intel® Xeon® processor-based workstation with more RAM, robust processors and faster hard drives will increase SolidWorks productivity so much that it typically pays for itself in six months via accelerated design iterations.

How do I enable performance pipeline in SOLIDWORKS 2020?

Click Options or Tools > Options > System Options and select Performance.

What does large assembly mode do in Solidworks?

Large Assembly Mode is a collection of system settings that improves the performance of assemblies. You can turn on Large Assembly Mode at any time. You can also set a threshold for the number of components to automatically open the assembly in Large Assembly Mode when that threshold is reached.

What is SpeedPak solidworks?

A SpeedPak configuration is essentially a subset of the parts, faces, reference geometry, sketches, and curves of an assembly. … Because only a subset of the parts, faces, reference geometry, sketches, and curves is used, memory usage is reduced, which can increase performance of many operations.

Does RAM speed affect SOLIDWORKS?

Adding more RAM to a slow system is a cost-effective way to boost performance. Having insufficient RAM creates a bottleneck for processes and acts as a sort of speed limit on your system. If a system often uses close to 100%, then adding more will boost performance.


While a certified video card is important SOLIDWORKS is a CPU bound application, you’ll see more performance gains from a faster CPU. For SOLIDWORKS 2019, the new performance pipeline requires Nvidia Quadro series cards Kepler, Maxwell, Pascal and Volta that support OpenGL 4.5.
