Beat Saber is on Steam and is also the best selling VR game of all time, so yeah I’d say it will work. I’d be extremely surprised if it wasn’t one of the very first games Valve worked on FEX & proton optimisation for.

As the former owner of an E36 and then an E90 I can tell you that the more modern ones still piss oil just as badly. And the consequences can be much worse (read: expensive) to boot.
