FPS Drops After an Update
· 5 min readIf Phantom Blade Zero FPS drops after an update, complete any required shader recompilation, check whether mods are installed and compare the same scene with the same settings before attributing the problem to the patch. Version 1.0302256 changes PC shader behavior and warns about incompatible mods. The collected material does not establish a universal post-update regression or one setting that fixes every machine.
Establish a comparable before-and-after case
Record the patch version, graphics settings, resolution and the exact area where the drop happens. A comparison between a quiet room before an update and a crowded fight afterward cannot isolate the patch as the cause. Repeat a short route or encounter whose conditions you can recognize, and distinguish a brief hitch from sustained low performance.
Also check whether an option changed or whether ray tracing is enabled. The patch describes a separate compilation path for ray-tracing shaders after that setting is enabled and the game is restarted. That startup behavior should not be mistaken for a permanent frame-rate result before normal gameplay has been tested.
Remove compatibility variables first
The official note explicitly warns that some third-party mods can cause issues after updating. Test without those modifications before combining the new patch with an additional performance mod. Follow each mod's removal instructions so that the comparison actually uses an unmodified installation rather than a mixture of old files and new settings.
Verification is relevant if the client update was interrupted or files may be incomplete. Let it finish once, then retest the same symptom. It is not useful evidence to repeatedly verify unchanged files while also changing several unrelated graphics options between attempts.
Report the scope of the remaining issue
If lowering rendering load changes the sustained frame rate but not the hitch, record both observations separately. If the problem is limited to a particular region, include that location instead of describing the entire game as equally affected. If a controller connection changes the result, report that comparison as well because the official patch identifies a Bluetooth-related case.
The collected reports provide symptoms, not controlled measurements for every configuration. This page therefore offers a comparison procedure rather than a guaranteed percentage improvement or a claim that a newer driver always solves the issue. A reproducible report with the unchanged baseline is more useful than a long list of untracked tweaks.
Preserve the pre-change settings
Before testing another option, write down the settings that produced the current result. This is particularly useful after an update because a changed ray-tracing state can affect both rendering and the next shader-compilation step. Without the baseline, a later improvement may be real but difficult to attribute to any one change.
Compare the symptom that matters rather than selecting whichever measurement looks better. A short hitch and a sustained frame-rate drop can respond differently, even in the same region. Keep both observations in the report if one improves and the other remains, because that distinction is more informative than calling the whole update fixed or broken.
What version 1.0302256 actually changed
The official patch note describes performance improvements in certain areas, not a universal frame-rate fix. On PC it also changes shader compilation, reduces stuttering associated with Bluetooth-connected controllers, and fixes NVIDIA Reflex Auto behavior when V-Sync is enabled. Each statement has a limited scope, so it should be matched to the symptom you are experiencing.
For players who previously had ray tracing disabled, the first start after this patch requires a one-time shader recompilation. Players who already had ray tracing enabled follow a different startup path, and enabling ray tracing later makes its shaders compile separately on the next restart. A compilation screen after the update is therefore not by itself evidence that the installation has broken.
The note also warns that some third-party mods are incompatible with the update. If a problem begins after patching a modified installation, remove those modifications according to their own instructions and test the unmodified game before adding more fixes. The official note is dated November 3 on the game website, while the collected Steam announcement is dated November 4; those are source dates, not proof of two different patches.
Make one reversible comparison at a time
Record where the issue happens, which patch is installed and whether the same action reliably reproduces it. A crash during launch, a long shader-compilation screen and a hitch while moving through a particular area are different symptoms. Keeping those cases separate makes it easier to judge a change and avoids applying an unrelated fix merely because it appears in a search result.
Finish pending client updates and verify the installation if files may be incomplete. On Steam, the documented check is under the game's Properties, then Installed Files, then Verify integrity of game files. Let the verification finish before testing again; repeatedly running the same check without a changed result adds little information.
For graphics-related symptoms, compare the same location with a lower rendering load and ray tracing disabled, then restart when the setting requires it. Restore the previous option if it makes no difference instead of accumulating changes you can no longer explain. These are diagnostic comparisons, not guarantees of higher FPS, and this wiki has not benchmarked your particular hardware.
Keep the results useful for support
A useful technical report identifies the platform, patch version and the action that reproduces the problem. Add the graphics configuration and input connection when the symptom involves rendering or controller behavior, then state whether the installation contains mods. Those details let another person compare the same case instead of guessing whether a launch failure and a brief traversal hitch are related.
Include the result of each relevant comparison, including changes that made no difference. If a wired connection behaves the same as Bluetooth, that observation helps narrow the situation without proving that the patch's controller fix never works. If lower rendering load changes average performance but leaves one specific interruption, preserve both results instead of describing the comparison simply as successful or unsuccessful.
The official notes are the reference for what the developer says changed, while community reports can suggest additional symptoms to investigate. Neither replaces a reproducible case on your own configuration, and this guide does not claim to have tested your hardware. Stop adding unrelated fixes once you have a clear report that the supported comparisons have not resolved, and take that evidence to the official support channel.
The official shader-cache recommendation
S-GAME also recommends rebuilding the game's shader cache when crashes or stuttering follow this update. The published cache path currently appears without directory separators, so confirm the exact cache folder with official support before removing files. This recommendation concerns shader-cache files, not the installation directory or saved games, and relaunching afterward triggers recompilation.
