And how do you go about that? Do you adjust your window size and extensions on a site-by-site basis?

What’d they do?

I have a reasonable amount of faith in Valve. I think their rising tide lifts Linux as a whole, so that’s good.

I doubt Valve would back of from the openness

Not on the short term, but who knows. If SteamOS becomes a major player in the PC space, at a post-GabeN Valve–

But that will take many more years, if ever it does happen. I do think it is a legitimate reason to be somewhat cautious.

Maybe. As it stands Valve is rather open with their implementation, but who’s to say it will remain indefinitely so.

I do get the desire, though. I’ve gone to Bazzite and Fedora and – even though it’s a lot better than just a year ago – it still requires some commandline tweaking. It isn’t entirely smooth sailing yet.
Will SteamOS be? I do have some doubts.

Especially with microsoft seemingly giving up on (gaming) hardware

Those companies aren’t exactly releasing consumer-facing distro’s, though.

If you want to play just controller games, this one is probably overkill and maybe a bit bulky. I guess the HD haptics are neat.

Then again, it likely won’t be any more expensive than the scam amount of money microsoft charges for their basic, non-HAL effect, non-gyro, basic haptics controllers.

Valve has only made mention of streaming bandwidth, nothing about the game being rendered (like how PSVR2 does it). As it stands it won’t do anything for the GPU performance.
Maybe there’s some sort of API games will be able to hook into, I seriously hope so.
