Why is Starfield's framerate worse in cities than in space on the Steam Machine?

Because cities like New Atlantis are CPU-bound, not GPU-bound. The engine simulates crowds, NPCs, and physics that lean hard on the Machine's 6-core Zen 4 chip. Space and exteriors lean on the GPU instead, which has more headroom, so they run noticeably better. Lowering graphics settings won't fix the city dip — lowering Crowd Density will help more.

Should I use FSR in Starfield on the Steam Machine?

Yes. Starfield ships with AMD FSR built into its menu, and on an RX 7600 -class GPU it is one of the biggest free performance wins available. Use FSR Quality at 1080p as your default, dropping to Balanced if you need more cushion in heavy scenes. It cuts the GPU's pixel workload without you having to gut individual settings.

Can the Steam Machine run Starfield at 4K?

Not honestly, no. With an RX 7600 -class GPU and an 8 GB VRAM ceiling, native 4K in Starfield is out of reach for a stable experience. The realistic target is 1080p high with FSR . If 4K gaming is your goal, check which device for hardware better suited to it.

Will high textures cause stutter on the Steam Machine's 8 GB VRAM?

Ultra textures can, by overrunning the 8 GB budget and causing pop-in and frame-time spikes. High textures at 1080p generally stay within budget and look nearly identical. If you notice late-loading textures or hitching when turning quickly, step texture quality down one notch first — that is almost always a VRAM symptom, not a GPU-power one. These figures are estimated; measured numbers will follow.

Best Starfield Settings on the Steam Machine

Starfield will run on the Steam Machine, but it is one of the more demanding games you can throw at this box, and the bottleneck is not where most people expect. We do not yet have a measured, curated SteamFPS verdict for Starfield on the Steam Machine, so treat everything below as estimated — derived from the game's well-documented PC demands plus the Machine's RX 7600-class GPU and 8 GB VRAM ceiling. Real measured numbers will follow once we test the retail unit. Until then, here is how to set it up for the smoothest ride.

The short version

Starfield is CPU-heavy in cities and VRAM-hungry everywhere. The Steam Machine's Zen 4 6c/12t chip and 8 GB VRAM are both pressure points, just in different places. Your job is to leave the GPU headroom for combat and exteriors while not asking the CPU to do more than it can in New Atlantis. The realistic, honest target here is 1080p high with FSR, holding a stable framerate rather than chasing a high one. This is not a native-4K title on this hardware — see which device if 4K is your priority.

Start from the right preset

Pick the High preset as your baseline, not Ultra. Ultra spends GPU and VRAM on contact shadows and volumetrics that you will largely give back below.
Set render resolution to 1080p. Pushing 1440p native on an RX 7600-class GPU in this engine leaves no margin for the heavy zones.
Turn on Starfield's native FSR (it ships with AMD FSR upscaling built into the menu). Use Quality mode at 1080p, or Balanced if you want more cushion. Native FSR is one of the biggest free wins here because it cuts the GPU's pixel load without you touching individual settings.
Enable the in-game dynamic resolution / FSR sharpness controls if you dislike the slightly soft look upscaling can give — a touch of sharpening goes a long way.

Understand the New Atlantis problem

This is the single most important thing to internalize. Starfield's cities — New Atlantis above all — are CPU-bound. The engine simulates crowds, NPC routines, and physics that hammer a 6-core part. When your framerate sags walking through the city center while exteriors and space combat feel fine, that is the CPU talking, not the GPU.

What this means in practice:

Lowering GPU settings (shadows, textures, resolution) will barely move your city framerate. Do not chase it there.
The settings that do help cities are the ones that reduce simulation and crowd load, covered below.
Accept that New Atlantis will be your worst-case zone. Tune for a floor you can live with there, and the rest of the game will feel comfortably better.

What to cut

Trim these first — they give back the most for the least visual cost:

Shadow Quality → Medium. Starfield's shadows are expensive and the drop from High to Medium is hard to notice in motion.
Contact Shadows → Off (or Low). A heavy, low-payoff effect. Turning it off frees real GPU time.
Volumetric Lighting → Medium. Helps in foggy interiors and atmospheric exteriors where it costs the most.
Crowd Density → Medium or Low. This is your city CPU lever. Fewer simulated NPCs is the most direct way to lift your New Atlantis floor.
Motion Blur / Film Grain / Depth of Field → personal taste. These are nearly free performance-wise; cut them for clarity, not frames.
GTAO / Ambient Occlusion → Medium. A small, safe saving with minimal visual hit.

Leave Particle Quality and Reflections at High unless you are still short — they carry a lot of Starfield's visual identity.

The 8 GB VRAM texture trap

This is the other half of the equation. Starfield's high-resolution texture streaming can overrun 8 GB, and when VRAM fills, you do not get a clean framerate drop — you get stutter, texture pop-in, and frame-time spikes that feel far worse than a lower average.

Keep Texture Quality at High, not Ultra, at 1080p. High looks excellent and stays inside the VRAM budget more reliably.
If you see textures load in late or hitching as you turn quickly, step textures down one notch before touching anything else.
Watch the in-game or Steam performance overlay for VRAM near the ceiling. On an 8 GB card, sustained near-cap usage is your warning sign.
Desktop mode in KDE Plasma lets you confirm nothing else is eating VRAM in the background before a long session.

A stable target to aim for

Set your expectation around a locked, consistent framerate at 1080p high + FSR Quality, not a number that swings 30 fps between space and city. Concretely:

Use the in-game frame cap (or a system-level cap) to lock to a rate you can hold in New Atlantis, not the rate you hit in open space. A held floor feels dramatically smoother than a high ceiling that collapses in cities.
If the city floor is uncomfortable, lower Crowd Density first, then resolution scale via FSR, before touching texture quality.
Treat exteriors and space as "free" — they will run well above your city floor, so do not over-tune for them.

We will publish measured Steam Machine framerates for Starfield once the retail unit is in hand. For now this profile is built to be stable and honest rather than to claim a number we have not verified. For more tuned profiles, see /games and our best Steam Machine games list.
