System Requirements

The minimum recommended workstation profile for running OpenTunnel Designer is:

Processor

Intel® or AMD® processor 2.5 GHz or greater

Memory

16 GB minimum 32 GB recommended. More memory almost always improves performance, particularly when working with larger models

Hard Disk

Minimum 25 GB free disk space (Minimum 42 GB disk space if additional companion applications/products included)

Video

See the graphics card manufacturer for latest information on DirectX drivers. 1 GB of video RAM or higher is recommended. If insufficient video RAM or no graphics card supported by DirectX can be found, OpenTunnel Designer attempts to use software emulation. For optimal performance, graphics display color depth should be set to 24-bit or higher. When using a color depth setting of 16-bit, some inconsistencies will be noted.

Screen Resolution

1920 x 1080 or higher.

MSAccess 64-bit engine
