This… doesnt make any sense… For so many reasons.

1. What exactly do you think a TPM does because it certainly doesnt have the processing power to validate anything. It just stores keys, potentially without you being able to access them (which is a heinous abuse of your autonomy but we live in a dystopia where people just somehow don’t care).

2. Steam machines aren’t unique in having TPM modules. Most computers do. Even Apple computers have their secure enclave.

3. Cheats can always be ran on a second pc, and there isn’t a way to thwart this. The ever invasive anti cheat options all trying to avoid writing proper server side validation and fog of war schemes just lose you privacy while not working, but blood thirsty gamers will lose their minds and accept anything if they think it slows down cheaters.
