Client-side, nothing uploaded
Config Tuner
Load your client.cfg, tick the changes you want, download
the tuned file.
This reads client.cfg — the game's own
settings, line by line, in this browser tab. The PC
Audit reads the machine: Windows, drivers, power, the display. Different
input, different findings.
About your machine
?
Above 4 cores the page takes core 0 out for Windows before it derives anything, and at 8 or more it leaves one further lane for everything else on the machine. If you pinned Rust with-cpu_affinity, type the number of physical cores
in that mask instead — a mask already leaves core 0 out, so
nothing is reserved twice.
Load your client.cfg
Close Rust first — it rewrites client.cfg on exit.

Or paste the file contents
What about keys.cfg?
keys.cfg sitting next to it is your
keybinds. This tool never reads or writes it — that file has its own
surface, the Bind Builder.Review the recommendations

What your file says
Why are some rows unticked?
0 other settings from your file — kept exactly as they are
Check what changes
Line by line, at its own line number. - is the line your file has now, + is the line the download writes in its place. Everything without a marker is copied across untouched, and all of it is here to read.
Putting it back
Four steps, and step 2 is your undo.
-
Close Rust
-
Move your current file to the Desktop
If your file extensions are hidden
Out of thecfgfolder, not renamed in place: with hidden file extensions a rename to .bak often silently becomes .bak.cfg. The Desktop copy is your undo. -
Move the downloaded file in
If this is your second download
Into thecfgfolder, and check its name is exactlyclient.cfg. A repeat download becomesclient (1).cfg, which Rust ignores. -
Start Rust
To go back: delete the new file and move your Desktop copy in again.
Keep going
Your cfg is done. What is left is Windows-side, which no config file can reach.
