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.
In my personal experience, drivers and basically everything where more straight forward (I’m on an Nvidia card). Just boot and run with significantly better performance than windows. On my crappy laptop with only integrated GPU same thing. Maybe because I don’t play any anti cheat games. Also in the indie sector there is a bit more effort on proton compatibility, basically all I have tried just work.
