BeatSage's results are hit and miss. I've uploaded a dozen of my favorite trance songs - some turned out completely unplayable, several actually worked out pretty well.
I wouldn’t personally recommend the official link cable — it’s expensive, and in my case it was flaky. I’m currently using a cable made by Cable Matters[0] that works well.
Most people buy the Steam version, though either can work. I personally lean more towards Steam so if I change headsets to something non-Facebook (like Valve’s rumored upcoming quest competitor), I can still play Beat Saber without a second purchase or weird hacks.
For installing mods, ModAssistant[1] has worked well for me. It’s pretty foolproof; the “standard” mods are pre-selected for installation by default, so for a minimal setup just open ModAssistant, point it at your Beat Saber installation, and install the standard mod set. From there you can search and install custom maps in-game.
I don’t have too many other useful links for you, but r/beatsaber on Reddit is pretty active and good for asking questions that haven’t already been covered by that subreddit’s wiki.
Airlink works surprisingly well and it's so much nicer to play wirelessly. You might need to connect a wireless (AC or better) access point to your computer if your existing wifi AP is in a different room, though.
I tried Air Link but even with all-wifi-6 hardware and the router sitting 20ft away, the video quality was garbage. I didn’t try to tweak settings too much though, maybe there’s some magic trick.
I started with the official cable, but honestly, it's not teenager proof and it's expensive to replace when the USB-C connector on the end is ripped out vigorously.
I'm now using an active booster one from Amazon that was about £20.
I have:
1. A Quest 2
2. A PC with an RTX 20XX graphics card (usually running Linux, but can boot into Windows 10) and USB C port
3. Beat Saber (standalone version)
I guess I need:
4. A long USB C cable (or the official one)?
5. Beat Saber for PC (best to buy on Oculus or Steam?)
6. Some instructions for finding, installing and using these community mods.
Is there a particular place (e.g. Reddit community) that's the best place to find 'getting started' info?
