# About This Release

As the release of ViDi 4.1.3, VisionPro ViDi now supports NVIDIA GeForce® RTX™ 30 series (RTX 3090, RTX 3080 and RTX 3070). ViDi 4.1.3 is the version discriminatively dedicated to RTX™ 30 series for the training of the tools (Blue, Red, Green), so you may not use previous versions of GPUs (RTX™ 2080 Ti or older) with ViDi 4.1.3 for training tasks. This means that on ViDi 4.1.3 you must train the tools only with RTX™ 30 series but you can still process images with these trained tools with the older versions of GPUs, for example like RTX™ 2080 Ti.

Training: training the tools (Blue, Red, Green) is only available through RTX™ 30 series.

- If you're exploiting multiple GPUs, all of them should consist of RTX™ 30 series.

Processing: processing with the trained tools is not only available through RTX™ 30 series but with the older versions of GPUs.

- Single GPU: You can use either one of the RTX™ 30 series or the one among the older versions of GPU for the processing task.
- Multiple GPUs: You can utilize other versions of GPUs, but to use multiple GPUs, they must all be of the same type and have the same amount of memory.

Note:

- The VisionPro, Designer and ViDi software require that a valid Cognex Security Dongle be installed directly to PCs running the software during all phases of operation (programming, processing, training, testing, etc.). Any attempts to temporarily remove, substitute, or share a Cognex Security Dongle may cause your system to operate incorrectly, and may result in the loss of data.

  When ViDi is configured for the Client/Server functionality, and a computer has been configured as a server, the Cognex Security Dongle must be attached to the server, but the client(s) does not need a Cognex Security Dongle.

- Sample code is included with the ViDi 4.1.3 installer. The resources for the sample code (ViDi 4.1 Sample Code Resource.msi), which include images and workspaces, are available for download from the Cognex Support Site.
- For more information about new API functionality in this release, see the Cognex ViDi Suite .NET Library and Cognex ViDi Suite C API help files.
