This struck me too, if you’re relying on instruments that exist in a universe where its constants are changing to measure those constants, then it seems very natural to me that your measurements would not necessarily change.
The constants instruments use to measure other constants might change at the same rate, leaving measurement results constant.

Then again, I’m not a physicist, so I’m nowhere near an expert.

Actually, if you’re interested, gaming on Linux is great nowadays.
Nvidia GPUs are not really well supported, but they work.
However, if you game using Intel integrated graphics or an AMD GPU, the performance is perfect.
On steam I have yet to encounter a game that does not run well using Proton.
