Buffer Size message?

[gub]

I've been experiencing an issue with my Protools session.

Normally, everything runs smoothly, but whenever I update the OS (for example, to Ventura), the PT session starts calling for me to increase the buffer size, although my buffer size is set at 1024. This problem seems to go away on its own over time, but it reappears after the next update. Although large mix sessions have thrown up the same problem when I run Ozone 11 with AI on the Mix Bus and sometimes the stability of some of Protool sessions do have crash issues, although not common.

So, my main question is: am I optimizing my current system correctly? Should I consider getting a better audio interface with DSP to improve performance? Do I need to replace my Focusrite Clarett 8pre? I use a lot of plugins from Superdummer, Avenger, NI, and others.

I'd like to hear some ideas from the Avid community on what I should be considering.

Thank you
