FlexSim's system requirements are divided into two tiers:
- Minimum: Most modern Windows PCs meet FlexSim's minimum requirements. While the minimum requirements are adequate to trial the software, they may be underpowered for many common simulation modeling scenarios.
- Recommended: Following the recommended specifications will give you the best experience using FlexSim Simulation Software. Many common modeling scenarios require this added performance.
Review our FlexSim Answers article Recommended System Requirements for an in-depth discussion regarding the hardware components that make the most difference when building and running your simulation models.
Minimum System Requirements
Most desktop and laptop computers produced in the last few years meet FlexSim's minimum requirements. A system that meets these minimum requirements will allow you to:
- evaluate FlexSim
- work through the tutorials
- build and run small to medium-sized models
A 64-bit edition of Windows under current Microsoft extended support 1
FlexSim is tested and designed for Windows personal computer systems 2.
A modern x64 Intel or AMD processor
To meet minimum requirements for performance, compatibility, and vendor support (such as driver updates) we recommend a CPU produced within the last 5 years, such as:
ARM processors are not supported.
8 GB RAM or more
A GPU supporting OpenGL 3.1 or higher
To meet minimum requirements for performance, compatibility, and vendor support (such as driver updates) we recommend a GPU produced within the last 5 years, such as:
You may need to update your graphics driver for FlexSim to work properly.
See the FlexSim Answers article Graphics Compatibility - Common Problems and Solutions for more suggestions on improving graphics compatibility and performance in FlexSim.

For the best experience - and for larger, more graphically intense, customized, or complex models, including using features such as importing CAD drawings, custom 3D objects, using the experimenter or optimizer, etc. - we recommend certain upgrades above the specifications listed in the minimum requirements.
A high-end computer system produced within the last two years will typically include such specifications:
|Operating System||The most recent version of Microsoft Windows 11.|
A CPU scoring 20,000 or better in the PassMark - CPU Mark multi-thread benchmark, and 2800 or better in the single-thread benchmark, such as:
|RAM||32 GB RAM or more|
A GPU scoring 14,000 or better in PassMark - G3D Mark benchmark, such as:
Once an operating system reaches its end of extended support with Microsoft, FlexSim no longer actively supports that OS. Windows on ARM is not supported.
FlexSim Software is designed for and tested on Windows personal computer systems. Remotely connected systems, thin-clients, virtual operating systems, virtualized GPUs, and other non-PC environments are not tested or directly supported. FlexSim Software requires compatible 3D hardware and driver support, which may be missing from such environments.
Certain non-PC environments may successfully run FlexSim Software and meet your compatibility and performance needs. FlexSim provides no guarantees about the suitability of such environments. If you choose to use FlexSim Software in a non-PC environment, please test thoroughly and understand that FlexSim will not be able to provide more than general system support for your unique environment.
FlexSim Software uses functionality provided by Microsoft's latest .NET framework. A compatible .NET framework is already installed on most computers, though if necessary, it can be downloaded directly from Microsoft.
