Does anyone play Destiny 2 on SD?

Unless something has changed very recently, Destiny 2 does not work under Proton because the Anti-cheat isn't compatible. Windows is an option, but I'd really recommend a dedicated Windows handheld for that instead of the Deck.

I haven't tried Windows on the Deck itself, but based on 6800u performance, you're looking at maybe getting a solid 30fps on lowest settings. Destiny 2 is not a very well optimized game atm, and even the Ally at 20w can have trouble holding good performance in Neomuna or the Tower.

Not only does it not work on Linux but if you attempt to circumvent this, you may be banned.
The DRM Destiny 2 uses is compatible, they just aren't enabling that flag in their builds. Destiny 2 ran great on Stadia and that was Linux.
- Maybe, but unless we're in there, it's hard to say for sure. Battleye supports it but given the clusterfuck that is the Tiger engine, they might be using an old or heavily modified version. Especially given how easily cheaters are getting past it atm, I would not assume they're keeping up to date on it without some evidence.
  
  Stadia limits the player's control of the system substantially and might not have even needed the anticheat, or the same anticheat, given it's closer to a console in terms of user's ability to run programs alongside the game to modify memory.
Windows is an option, but I'd really recommend a dedicated Windows handheld for that instead of the Deck.

Why is that?
- The Deck is designed for SteamOS and SteamOS is pretty much designed for the Deck. They're chocolate and peanut butter.
  
  I feel Valve's Windows support is not great -- it's a custom APU for them so you're getting your drivers through Valve, not directly from AMD's Adrenalin. The APU drivers are from March, I'm not sure if we've seen any Linux improvements since then on the APU side but months without GPU driver updates to address game compat issues doesn't encourage me.
  
  They don't officially support dual booting AFAICT, and given the size of modern games + Windows, I wouldn't want to dual boot on any of the offered SSDs tbh.
  
  If you've got a deck and really want a Windows-only game, it works. But given the easy availability of the Ally, and the upcoming non-extreme Ally, I can't imagine recommending anyone who wants to primarily play a Windows-only game get a Deck.
Thank you for the recommendation. I have a gaming desktop, so streaming from the SD is always an option.
- I can not get this to work. I remote stream alot of games to the deck but destiny 2 never works. It will launch on PC but never get a display on deck.

Bungie will actually ban your account if they detect you playing on SD the last I read.

That's only if you're trying to play it through the Steam UI, if you install Windows and run it like any other Windows machine it's fine.
- That's such bullshit that they make you do that though.

You could try it with geforce now. I used to play it on stadia a bit but I decided to try warframe when it shutdown. That works fine on deck

I set up a USB-C SSD with a Windows 11 installation just to test this.

Installing it as a normal Windows game works fine.

My friend has a Windows partition for it. Set it up day one. Works fine. Would be nice to have it native. I'm not running Windows just to play it myself.

I've tried using it via Remote Play and it's not bad. I have to adjust the resolution of course to fit the Deck better, but having the performance offered by my main PC is nice and the latency is negligible imo, on my home network (which I believe to be unremarkable)
