Got proof for that last claim?

I thought their sealed sender feature was meant to prevent exactly this scenario.

They haven’t dropped the requirement, but you have to manually go in and disable that check yourself on the windows 11 installer if you want to install it on a non-tpm 2.0 machine

Basically, it’s a faff that only the techie people will realistically do. Everyone else will just go out and buy new hardware.

This doesn’t affect valve at all though. It’s borrowing their tech that they’ve made open source, and figuring out how to use it elsewhere outside of steam.

Actually, it’ll benefit them. More eyes are on proton and any fix will benefit everyone, including games played via steam.
