Lagging Issues

Rhino seems particularly laggy after not using it between May and November. I’ve started up again with all the necessary application and system updates. Large projects which were slow but workable before seem unworkable when I open the same projects now. Wondering if anyone else has experienced this.
Rhino Version 7 SR34 (7.34.23267.11001, 2023-09-24) (current)

This may be Visualarq-specific. I know Va creates lag, but I enquire here – and separately on the Va site – to see if the lag can be attributed to either (or both) components.

Hi David -

If you were running an up-to-date Rhino in May, it would have been Rhino 7 SR29. You could install that to see if that makes a difference.

Windows Updates can mess with GPU drivers. It would probably be worthwhile checking these on the website of the producer of those devices.
