Or maybe they will launch Win 12 with optional TPM support.
Imho making the OS(es) TPM only cannot be good for their business, many people are still on Win 10 with no intention to switch, since their motheboard does not support TPM and do not want to upgrade PC / waste PCI-E slot on TPM extension.
There’s websites where you can check if a game can be played on Linux. For me personally I know a game I play a fair bit won’t work on linux for a fact, and most of the stuff I need I can get to work on Windows just fine.
