CPU and RAM maxed out on Windows 10 with Solidworks 2015

Question asked by Michael Bentfeld on Apr 18, 2018


I am setting up multiple new workstations for Solidworks for our company’s engineering department. The computers are spec’d as follows:

  • Dell Precision Tower 3620
  • Intel Xeon E3-1225v5 Processor – 3.3GHz
  • 32GB (2x16GB) DDR4 RAM (2400MHz)
  • NVIDIA Quadro P1000 graphics card
  • Windows 10 Professional 64-bit
  • 256GB SSD
  • Solidworks 2015 SP5 (upgrading is not an option at this time)

We are experiencing some problems.  When Solidworks is opened, two instances open and I can’t determine why.  As models are opened and closed during the day, performance of Solidworks degrades.  Our largest models are in the 150 – 200 MB range. By midday or so, the RAM and CPU are near maximum, and the rotation on models is jerky, even when opening a small model.  The more times we open and closed, the sooner we start seeing poor performance. Closing Solidworks and reopening it alleviates the RAM and CPU usage problem. I have confirmed Solidworks 2015 SP5 is supported on Windows 10.  Has anyone else seen this type of behavior? Can anyone recommend tweaks to resolve this issue?

Thanks in advance,
