Customers who use MicroSurvey CAD and newer NVIDIA Graphics Hardware Accelerators (the Quadro in particular) have reported a range of error messages or instability over the past years. We are happy to report that the release of MicroSurvey CAD 2022 and the latest NVIDIA driver package offer a significant improvement in performance and stability. Read this article to learn about configurations that will take advantage of this improved performance.

NVIDIA has added a new dedicated IntelliCAD profile to the driver. If the newer version of NVIDIA Quadro driver is chosen, the IntelliCAD engine can be automatically detected and run by NVIDIA card by default. For users who have already had a profile set up in NVIDIA manager, extra steps need to be taken to avoid the conflict. 

For details about the new NVIDIA driver released Oct 2021, see: https://www.nvidia.com/Download/driverResults.aspx/182957/en-us
