Lag issues

Rhino and Va seem particularly laggy after not using them 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.
Va version 2.13.2.17721 (current)
Rhino Version 7 SR34 (7.34.23267.11001, 2023-09-24) (current)

Hi @djhg there might be many reasons why the performance is slower, and not necessarily because of updates on the Rhino or the VisualARQ versions: changes in the display mode, amount of visible geometry, amount of objects, complexity of the geometry, clipping planes / sections / levels enabled…

Have you tried to unload VisualARQ (and Tibidabo) to compare any changes in the performance?

Can you share a model so we can test that performance on our machines?
