OK, so this 'small video' on running the full UE5.1 Fortnite experience on Steam Deck turned out to be a lot more involved than I thought it would be! Initially, as seen in my previous post, the Steam Deck seemed to be performing like a champion. Truth is, it was performing in a 'too good to be true' way and I quickly discovered that software Lumen (used to make 60fps possible on consoles) is not possible on Steam Deck. Somehow, selecting it defaults to standard rendering instead.

Yup, hardware-accelerated ray tracing is the only way to get Lumen working on the Deck - meaning that the hardware is being taxed disproportionately to what's happening on Series S and the other consoles. Even so, we're not a million miles away from 30fps. I'm not going to go into too much depth right now on how I've done this - but I'm definitely curious what you make of the resulting comparison video...

Bonus Material: Fortnite Lumen/Nanite - Steam Deck vs Xbox Series S

It took some effort, but we managed to get Lumen, Nanite and virtual shadows in Fortnite working on Steam Deck running under Windows! Which means it's time for another Deck vs Series S comparison video...

Would it be possible to play it in later state on 60fps? Maybe drivers etc not well optimized for ue5.1 yet? But the series s is the better choice here? What where the settings you ended up with? Grtz p.s like these videos

All will be revealed in the final video, but remember that Fortnite is not really playable on Deck right now. You need to use Windows, which is not ideal. SteamOS doesn't support the anti-cheat tools the game requires. I would say there is no chance whatsoever of running Lumen at 60fps on Deck. You could likely still use Nanite at 40fps though with Lumen disabled.

Thanks for the replay, im curious what the final video is.

Technically SteamOS can support EAC (Apex Legends uses it, for example), but EPIC doesn't want to allow Fortnite on Linux for alleged reasons that I don't completely buy into.

Really curious why software Lumen isn’t possible on Deck, surely a hardware limitation would be bypassed by running, well, in software. Still, great stuff, thanks for the progress update! Quite the curious one here.
