Steam Hardware

Here you can find reports on FH5 running on deck. You can also see here how it runs in 2026 after multiple patches. Personally I'd cap the fls at 50 and the cpu at 1300 and run the game with the frametime curve being a flat line.

When playing on the deck, one makes graphical setting sacrifices but avoids making the biggest one, which is giving asus and MS money for the absolute dumpster fire that is the allyX. Those things are failing at RRoD levels, so I'd be even more wary of buying it second hand. Try the legionGO, it's expensive but a far better machine than any ally.

Currently playing horizon 5 on it, only just makes it into the playable category in my opinion. I would expect 6 to not really be playable on it, but will have to wait and see.

I do believe the Ally plays Horizon 5 much better than the Deck. Still wouldn't trade the Deck for one though 😁

If you already have PC that runs the game well you can stream it to the steamdeck. I haven't tried using a secondary display while streaming

FH6 is supposed to based on the same engine as the new Motorsport game. FH6s minimum system requirements are even more than Motorsport. And Motorsport runs like butts even on a higher end PC. 5 might be playable, but 6 almost definitely won’t be.

Ive played forza 4 on it and its playable but if its docked and in 1080p it won't be a good experience. Idk if my standards are to high from years of PC gaming. You won't get 60fps and thats one of the games you really want nice reflections and high frames.

If you want to play forza take a look at the legion go S if you can find one for cheap

Forza 5 ran ok on my steam deck when I had it. I wasn't getting super high fps or anything, but it was stable, good enough to make the road my bitch whenever I had a spare minute.

The Steam Deck (and by extension any handheld) isn't particularly great for 3D games due to the power limitations. Those games do generally run, but they either need lower resolution or lower framerates, and almost always drain the battery faster.

Steam Deck can run Forza 5 okay enough, just don't expect it to look amazing, especially while docked. It won't be at the Xbox in terms of visuals and performance.

Based on how Motorsport ran on PC, I wouldn't count on it being a smooth experience for FH6 until we are proven otherwise.

Also you can stream you main PC to a steam deck, although you're going to want a wired connection if possible, especially if doing so while docked.
