Phantom Blade Zero launched on October 29, 2026, and it is already tearing up Steam's most-played chart. But before you fire it up, developer S-Game wants you to install a day-one patch, and PC players with the newest Nvidia driver should roll it back.
The update weighs in at roughly 5 GB on PC and 2 GB on PS5, where it shows up as version 1.301.524, according to IGN. It fixes a stack of bugs and improves ray tracing and path tracing performance across both platforms.
What the Day One Patch Fixes
S-Game also put real work into rasterization, the process that turns 3D models into what you see on screen. In plain terms: the game looks right even with ray tracing switched off. The studio said the patch ensures the scene's art style is perfectly conveyed on mid-range hardware and even handhelds like the Steam Deck.
Valve has not yet stamped the game as Steam Deck Verified, but S-Game said handheld devices have been extensively tested, so that badge is probably coming soon.
Nvidia Driver 621.01: The Problem Driver
Here is the part PC gamers need to hear. S-Game found performance problems with Nvidia's latest driver, version 621.01.
“We found that Nvidia's latest driver 621.01 has some unstable performance issues,” S-Game said in the patch announcement.
The developer recommends rolling back to driver 617.42, and choosing the clean installation option when you do. Stay there until Nvidia ships its next driver, which S-Game expects soon. Wccftech reported the studio's warning that 617.42 currently provides the best compatibility with the game.
Soulframe Liang, creative director and CEO of S-Game, laid it all out for players: “We've 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. We've also extensively tested the game on mid-range and lower-end PCs, as well as handhelds, and encourage you to give it a try.”
iXBT.games also reported the developer's warning that the latest Nvidia drivers may cause issues, alongside word that the patch improves ray tracing and path tracing and fixes a number of bugs.
Why Rasterization Work Matters
Plenty of studios ship games that only look good on a $2,000 rig. S-Game went the other direction. The studio says it tested Phantom Blade Zero on mid-range and lower-end PCs, plus handhelds, and built the visuals so the art direction holds up even with the fancy lighting turned off.
That is the free market doing its job. Developers who respect the customer's hardware get rewarded with sales and word of mouth. Ones who ship broken products get review-bombed. S-Game clearly picked a side.
A New Voice for the Lead Role
News also broke before launch that the original protagonist actor was replaced. Roger Craig Smith, the voice of Sonic the Hedgehog, now takes the lead role for the full launch.
The Reviews Are Strong
IGN's review scored Phantom Blade Zero a 9 out of 10.
“Phantom Blade Zero is an unbelievably smooth action game filled with memorable boss fights, compelling combat, and limitless swagger,” IGN wrote.
TwistedVoxel reported that the 5 GB patch exists to fix issues, with the studio recommending a rollback to 617.42 for anyone experiencing frame drops after installing the newer driver.
What Players Should Do Before Launching
If you pre-loaded the game, download and install the update before you launch it. If you have not pre-loaded yet, your download will include the latest version automatically.
For Nvidia owners, the checklist is simple. Check your driver version. If it is newer than 617.42, roll back to 617.42 and select the clean installation option. Then wait for Nvidia's next driver before upgrading again.
