You will find this pointer in the very first (summary) post of this thread:

Useful Windows Tools for analysis

  • Resource Monitor
    • …
  • Process Monitor
    • Provided by Microsoft for free via the regular app store as part of the Sysinternals Tools.
    • Performs a highly detailed analysis of almost all system activities
      • … by obtaining a full event recording for a certain period of time.
    • Process Monitor - Sysinternals | Microsoft Learn

After some time I noticed that Process Monitor does not really “record” the process activity but it “only” takes samples of the activity. So the recording is not 100% of all activity … but it feels like 80 to 90% of all file access gets recorded.
(OK … I should have read the documentation of Process Monitor … because this is clearly spelled out there … so I guess a lazy goose must discover it the hard way)

Process Monitor also allows a CSV export of the recordings which I then “post-process” … with find-replace-grep-sort-count etc.

Stability & Performance

  • Improved rolling cache usage

Sadly no additional information. So we will have to wait and see.

My thoughts exactly, when I read the release notes

It will be hard for us to measure any difference, but Asobo may have useful tools to measure hit ratio, texture throughput etc.

Having those cache analysis tools in Dev mode would be interesting.
