Wooshy's wuxia action game Phantom Blade Zero performs sharply on the Steam Machine but is somewhat blunted on the Steam Deck

Background: A Heavy Wuxia Game Meets Steam Machine

S-Game Studio’s Phantom Blade Zero is a lightly Soulsy sword-em-up built around effects-heavy martial artistry and a wuxia tale. The game is described as demanding more gigabytes than a mismanaged stadium, but that demand is doing little to stop people playing it. At least some players will therefore want to run the game on Steam Machine, the device also referred to as GabeCube.

The real question is not whether the game can be played, but whether its flashy moves, cinematic camera shifts, and dense effects can hold frame rates on a standard 1080p setup.

Early Warning: Linux Glitch Fears and a Steam Deck OLED Baseline

Two signs suggested trouble before Steam Machine testing began.

First, a comment on Oisin’s day one patch piece warned of heavy glitching on a Linux system. Second, a Steam Deck OLED, also a Linux system, was incapable of running Phantom Blade Zero at even close to a steady 30 frames per second. With the Low preset and nasty-looking Ultra Performance upscaling, the game’s flashy moves and jerking, or cinematic, camera shifts made for regular frame rate drops into the teens.

That baseline did not look promising for a heavier Steam Machine test.

Steam Machine Result: Medium Preset Reaches 45-60 Frames per Second

The Steam Machine proved much more resilient than the early warnings implied, even if it benefits from a few quality cuts. Realistically, the system will struggle if pushed beyond standard 1080p.

The Medium preset and Quality-level FidelityFX Super Resolution were enough for 45-60 frames per second in the reported play time so far. The High preset is at least playable without major bugs or stuttering, though it is susceptible to dips below 40 frames per second.

Main Bug: Steam Controller, Not Graphics or SteamOS

The only major technical problem reported was not caused by graphics or the Linux-based SteamOS. It came from the Steam Controller.

During boot, the system indicated that Official Gamepad Configuration was being used. However, an unresponsive map-opening button left the player immobile during a prompt tutorial, and without a map, lost.

The issue turns out to be a common bug with the Steam Controller specifically. It can be fixed by remapping the Select button in SteamOS controller settings to emulate the effect of clicking the touchpad of a PlayStation 5 pad. It is a quirk of PC gaming, but it was the actual blocker rather than the game’s visual workload.

After the Workaround: Playable, but Cutscenes Still Drop Frames

With that controller issue sorted, Phantom Blade Zero seems to work fine.

Nitpicking aside, some high-drama sequences are visibly less smooth than slower roaming sections, which can exceed 60 frames per second on Medium. Many cutscenes are not hard-locked to 30 frames per second like prerendered scenes often are, but they do cause heavy frame rate drops for little apparent reason. Still, the experience is reasonable when actually playing.

Settings: Keep Medium as the Base, Then Raise Selected Quality Options

The Medium preset with FidelityFX Super Resolution set to Quality works well as a low-effort configuration. But a few individual quality options are not terribly performance-sapping by themselves and can be tuned upward for a slightly nicer-looking wuxia tale with minimal drawback.

The suggested settings are:

• Motion Blur: Off
• Super Resolution Method: FidelityFX Super Resolution
• Super Resolution Quality: Quality
• Dynamic Resolution Quality: Off
• Super Resolution Output Scale: 100%
• Frame Generation: Off
• Super Resolution Sharpness: 10
• Ray Tracing Quality: Off
• Shadow Quality: Medium
• Reflection Quality: Medium
• Post-Processing Quality: Ultra
• Lighting Quality: Medium
• Effects Quality: Medium
• Material Quality: High
• Ambient Occlusion Quality: Very High
• Depth of Field Quality: Ultra
• Motion Blur Quality: Not applicable because Motion Blur is switched off
• Anti-Aliasing: Not applicable because FidelityFX Super Resolution replaces it
• View Distance: Medium
• Character Texture Quality: High
• Character Model Quality: High
• High-Quality Hair: Off
• Environment Texture Quality: High
• Environment Model Quality: High
• Environment Detail Quality: High

The important tweaks are Dynamic Resolution Quality: Off and Super Resolution Output Scale: 100%. On their defaults, both make the game uglier than it needs to be.

FidelityFX Super Resolution upscaling can leave a bit of roughness on certain edges, but at 1080p the same issue can appear even when FidelityFX Super Resolution is set to Native Resolution. In that case, the extra frames are worth taking.

Current Stage: A Playable Steam Machine Build with a Known Workaround

Phantom Blade Zero is currently in a playable state on Steam Machine, with the key numbers pointing to a standard 1080p target. The Medium preset with Quality-level FidelityFX Super Resolution delivers 45-60 frames per second, while the High preset remains playable but can dip below 40 frames per second.

The early Linux glitch warning and the Steam Deck OLED baseline showed that the game is demanding, but the Steam Machine result shows that quality cuts and a Steam Controller remapping fix are enough to keep the experience moving. The practical stage is not a fully polished native 1080p lock, but a workable, tunable build: use Medium as the base, apply the listed settings, and treat the controller bug as a known workaround rather than a game-breaking blocker.
