How to Get Phantom Blade Zero Running Its Best on PC Right Now
S-GAME's wuxia action RPG just launched, and its own day-one post disagrees with NVIDIA's newest driver. Here's which driver and settings to actually use.
Phantom Blade Zero, S-GAME's wuxia action RPG built on Unreal Engine 5, launched on PC and PS5 on October 29. The studio spent 50 extra days of development polishing character models and environments before release, and that extra fidelity shows up in a PC spec sheet that leans hard on upscaling rather than raw horsepower. Before you start swinging Soul's blade through the Wulin, there's one piece of launch-week guidance from the developer itself that's worth following before any of the in-game sliders: which NVIDIA driver to actually run.
Skip NVIDIA's newest driver — for now
NVIDIA shipped a dedicated GeForce Game Ready Driver, version 621.01, ahead of launch, and its own GeForce driver announcement positions it as the one to install for Phantom Blade Zero, citing DLSS 4.5 with Dynamic Multi Frame Generation and DLSS Ray Reconstruction support for RTX cards. But in a day-one post on the game's official Steam news feed, S-GAME said it found the opposite in its own testing, reporting performance instability on 621.01 and naming 617.42 as the version that currently runs best. The studio's advice is specific: anyone already on a newer driver should roll back to 617.42 using a clean installation and stay there until NVIDIA ships its next update.
If you're on an RTX card, that means opening the NVIDIA App (or Device Manager, if you're not using it) and rolling back to 617.42 before you install Phantom Blade Zero's day-one patch, rather than grabbing whatever driver NVIDIA is currently pushing. A clean install — wiping existing driver files rather than just installing over them — is what S-GAME specifically recommends, and it's worth doing through the NVIDIA App's own clean-install option rather than skipping that step.

Minimum vs. recommended: what you actually need
Per the Steam store page's official PC requirements, the minimum spec calls for an Intel Core i7-8700K or AMD Ryzen 5 3600, 16 GB of RAM, and an NVIDIA GeForce GTX 1660 or AMD Radeon RX 5500 XT, targeting 1080p/30 FPS with upscaling enabled. The recommended tier steps up to an Intel Core i5-10600K or Ryzen 5 5600X, the same 16 GB of RAM, and an RTX 3060 Ti or Radeon RX 6700 XT, aimed at 1440p/60 FPS with upscaling enabled. Both tiers list 145 GB of storage and explicitly call for an SSD rather than a hard drive, so if the game is stuttering on load screens, a slow drive is the first thing to rule out.
- Set your target resolution first, then enable upscaling before touching anything else — the official specs assume it's on even at the minimum tier.
- Confirm the install is on an SSD; the minimum spec requires one, it isn't just a recommendation.
- 16 GB of RAM is the floor at every tier, so if you're running 8 GB you'll want to upgrade before troubleshooting settings further.
Ray tracing off is the intended look, not a compromise
S-GAME has been unusually direct about this. In the same day-one post, the studio said it had "spent a great deal of time refining the game's rasterized visuals so that each environment stays true to our art direction even with ray tracing turned off," and that it had "extensively tested the game on mid-range and lower-end PCs, as well as handhelds." That's a developer explicitly telling players that the non-ray-traced mode isn't a stripped-down fallback — it's the version the art team built around.
“We've observed some performance instability with NVIDIA's latest 621.01 driver. Based on our testing, version 617.42 currently offers the best experience in Phantom Blade Zero. If you've installed a driver newer than 617.42, we recommend rolling back to 617.42 and choosing the clean installation option.”Soulframe Liang, Creative Director and CEO of S-GAME

In practice, that means most players should leave ray tracing off entirely rather than treating it as a setting to chase. If you've got an RTX 4080-class card or better and want the path-traced version of the Wulin's shifting light and shadow, DLSS Ray Reconstruction (once you're back on a stable driver) is built specifically to support that mode — but it only does anything once path tracing itself is switched on, so there's no reason to enable it otherwise.
Display, aspect ratio and control options worth checking
The same launch-day post covers a few settings worth digging for before you assume the menus only cover the basics. S-GAME says it adapted the game for every major screen aspect ratio, including standard 16:9 monitors and TVs, 16:10 laptops and handhelds, and ultrawide displays beyond a 3:1 ratio — so if you're playing on an unusual panel, check the display settings before assuming black bars are unavoidable.
On the audio side, the studio added a setting specifically for the tone of clashing blades, letting you tailor how each hit sounds rather than relying on a single fixed mix — a small but combat-relevant option worth testing if blade impacts feel too sharp or too dull on your setup. Controller users get three button-layout presets on PS5, and S-GAME says PC offers even more flexible remapping on top of those presets, so it's worth opening the control menu before resigning yourself to the default binds.
The day-one patch, and what it actually fixes
Alongside the driver warning, S-GAME's post confirms a day-one patch of roughly 5 GB that the studio says "significantly improves ray tracing and path tracing performance, alongside several bug fixes." If you pre-loaded the game, you need to download and install that patch before launching; if you downloaded after release, it's already baked into your copy. Combined with the driver rollback, that patch is the real explanation if your path-traced frame rate looked rough in the first hour after unlocking — both the patch and the correct driver matter more here than any individual graphics slider.
Quick settings checklist
- On RTX cards, roll back to NVIDIA driver 617.42 with a clean install rather than running the newer 621.01 driver, per S-GAME's own day-one guidance.
- Install on an SSD with at least 145 GB free, and make sure the day-one patch has actually applied before judging performance.
- Pick your target resolution, then turn on upscaling before adjusting anything else — it's assumed even at the minimum spec tier.
- Leave ray tracing and path tracing off by default; the rasterized mode is the one S-GAME built and tested its visuals around.
- If you're on a handheld or a lower-end laptop, know that S-GAME says it specifically tested those configurations — it's worth trying before assuming the game won't run.
None of this requires digging through third-party forum threads. Between S-GAME's own requirements page and its day-one Steam post, the developer has been unusually specific about how it expects the game to be run this week — right down to naming the exact driver version to avoid.
