Welcome the radiant beginning of spring together with PLATiNA :: LAB🌸
From Wednesday, Mar. 4, 13:00 to Wednesday, Mar. 18, 12:59 (UTC+9)
We have identified an issue where play records were incorrectly reflected in certain situations. We would like to inform you that a non-maintenance server update has been implemented today to address this matter.
An error was found where achieving a JUDGE RATE exactly matching a RANK threshold (e.g., 97.0000%) was processed by the system as a slightly lower value (e.g., 96.9999%).
This caused instances where a lower RANK was incorrectly assigned or where P.A.T.C.H. Points were awarded at a lower rate than the actual achievement.
We have confirmed that this was due to a 'floating-point error' within our internal system.
A non-maintenance server update was deployed today to prevent this issue from recurring.
We have conducted a full investigation into the limited number of existing records affected by this error and have restored them to their correct values.
As a result, some users may see an increase in their Top 50 P.A.T.C.H. Point totals. Please keep this in mind while playing.
Please note that even after this fix, the RANK of your personal best record may still appear lower within the game client in some cases. This is a visual display issue only; rest assured that the correct data has been accurately recorded on the server.
Thank you for your patience and continued support.
Hello, this is the HIGH-END Games / PLATiNA :: LAB development team.
Moving forward, we will use these periodic Developer Notes to transparently share update details and future plans.
This first article focuses on the Performance Optimizations implemented through our recent updates. Additionally, we would like to share how we are reviewing and planning to incorporate the valuable feedback you have shared with us.
The performance issues many of you have experienced stemmed from defects rooted in technical debt accumulated since the early design stages. Our team identified that these underlying problems became more apparent over the extended period of operation following our Early Access launch.
Key Background:
During the early phases, our focus was on rapid feature implementation, which led to a prolonged technical transition period. Consequently, core code remained in an inefficient structure without sufficient architectural refinement.
A significant amount of legacy code was not optimized for the \ + \ environment.
Ultimately, we determined that a comprehensive rebuild of the existing client was essential for a fundamental solution. As a result, we have focused our efforts on a large-scale overhaul of in-game performance optimization.
Our goal for “Performance Optimizations” involved a fundamental redesign and reimplementation of the rhythm game component of PLATiNA :: LAB (hereafter referred to as the 'Core Logic').
We focused on rebuilding the following areas from the ground up, including all closely integrated sub-elements. As a result, the vast majority of the source code for the rhythm game’s Core Logic has been rewritten:
Note Judgment (Hit Detection)
Note Rendering
BGM Playback
BGA (Background Animation) Playback
Visual Effects, including 'Key Beams' and other on-device animations
In rhythm games, the most critical element is processing user inputs with perfect timing. This requires the input detection process to run at an extremely high frequency without interruption.
To achieve this, the Core Logic thread of PLATiNA :: LAB is designed to operate at 1,000Hz, while the Input Polling thread runs at rates between 1,000Hz and 8,000Hz.
However, the default input system provided by the Unity engine has structural limitations when it comes to meeting the extreme precision required for high-end rhythm gaming. To overcome these barriers, our team has gone through extensive trial and error to develop and implement our own proprietary input system specifically optimized for PLATiNA :: LAB.
While rhythm games can calculate judgments based on a note’s visual position relative to the judgment line, we believe that time-based calculations—processing the exact moment a note passes the line—are essential for consistent and precise judgment. (In fact, PLATiNA :: LAB utilizes the latter.)
However, our legacy core logic was performing redundant operations alongside these time-based calculations. This created an inefficient structure where the computational load increased proportionally to the number of notes in a pattern.
This inefficiency clashed particularly with the new input system mentioned earlier, causing severe performance spikes in certain patterns with high note counts.
By completely stripping away these unnecessary operations, we have addressed the root cause of the performance degradation. The core logic is now optimized to deliver stable, consistent performance regardless of the total note count.
The root cause of the frame drops many of you experienced lies in the inefficient way the game managed available memory. To explain this, we first need to look at a process called “Garbage Collection (GC).”
During gameplay, the system performs Garbage Collection to clean up unnecessary memory. When this occurs, it can cause the game to momentarily stutter or freeze. To prevent this during active play, it is crucial to design code that minimizes unnecessary memory allocation.
Unfortunately, our legacy structure suffered from excessive memory allocation. This inefficient management caused the “GC burden” to accumulate quickly. Furthermore, this was exacerbated by an issue where memory was being allocated thousands of times per second in proportion to the \ setting. This is why those using higher polling rates or playing for extended periods experienced more frequent frame drops.
We have now restructured the game to prevent these unnecessary allocations, significantly reducing both the frequency of Garbage Collection and its impact on performance. We are also continuously reviewing further optimizations to eliminate any remaining vulnerabilities that could cause frame drops in the long term.
Through the “Performance Optimizations” efforts carried out so far, we have successfully addressed the major root causes of heavy performance loads in a step-by-step manner.
In particular, the overhaul of previously inefficient code into a more developer-friendly structure has laid a critical technical foundation. This ensures we can now swiftly identify and respond to any future issues.
Despite these achievements, we recognize that several tasks still require further attention and action.
We are aware of the persistent issue where the game client stops responding or freezes upon exit.
This phenomenon is closely tied to the process of releasing memory back to the system when a shutdown is triggered. Specifically, we have identified bottlenecks during the unloading of high-capacity sound assets as the most likely cause.
We plan to resolve this by optimizing the unloading process for sound and various other game assets.
The FMOD engine currently used in our game is originally optimized for spatial audio, common in genres like 3D FPS. Consequently, it contains several redundant features when applied to a rhythm game framework.
Our immediate priority is to stabilize the current FMOD-based system. Looking ahead, however, we plan to conduct a multi-faceted review of alternative sound engines that are more natively optimized for the unique requirements of rhythm gaming.
We are aware of the issues some of you faced when using non-QWERTY layouts or trying to assign special keys like \ in the settings.
These bugs were unintended side effects of our ongoing work to improve global keyboard compatibility. While many of these problems were prioritized and fixed in the latest patch, we aren't stopping there.
We are committed to upgrading our input systems to eliminate any conflicts with system-wide shortcuts and to ensure that the game flawlessly recognizes every single key press, exactly as you’ve mapped it.
In addition to the current \ and \ settings, many players have requested an option to adjust the absolute timing of when notes appear.
This feature is currently in the final stages of development and will be available in an upcoming update. Furthermore, we recognize that optimizing judgment settings can be daunting for new players. To address this, we are exploring ideas such as a “Judgment Setup Assistant” that automatically finds the ideal settings for each user.
We are planning a much wider array of customization features for the play screen than what is currently available. These options will be rolled out sequentially as soon as their development is finalized.
We have been carefully listening to your feedback regarding the current pause penalty system being too strict.
Originally, this system was introduced to ensure that players couldn't exploit the pause-and-resume mechanic to compromise the fairness of our ranking leaderboards. However, we deeply agree that this has resulted in overly restrictive constraints for a PC rhythm game environment that should encourage free play.
Consequently, we will be updating the system so that penalties are no longer applied to pauses made before the first note appears. Furthermore, we plan to eventually phase out the current penalty system entirely and replace it with a new system better optimized for the gameplay rules of PLATiNA :: LAB.
We are designing our \ feature to support a unified environment where all players can meet and compete, regardless of whether they are on Steam or STOVE.
However, building a robust multiplayer experience requires in-depth consideration—from server architecture and latency optimization to the establishment of dedicated gameplay rules. As such, we expect it will take some time to reach full completion.
Because we know how much you are looking forward to this feature, we are committed to delivering a highly polished result. We will continue to share our progress through future Developer Notes, so please stay tuned for further updates.
We believe the strongest motivation to keep playing a rhythm game is the sense of growth gained through “competing with oneself.” Systems like \ and \ are the core engines of PLATiNA :: LAB, designed specifically to support that experience. We plan to continue expanding these elements based on this core principle.
For instance, we aim to present a “Roadmap for Growth” through self-challenge by introducing features such as section-based performance analysis, goal-setting tools, and personalized song recommendations based on your current performance to help you break your P.A.T.C.H. high scores.
Most importantly, we are exploring various ways to offer support—such as integrated in-game guides—to make our existing systems more intuitive. Additionally, we are preparing official documentation for our website and Discord server so that you can easily access detailed information on all major systems in the near future.
We understand that the experiences of playing \ and \ patterns should be treated as distinct categories. Accordingly, we plan to update the P.A.T.C.H. scoring system so that scores for Standard and Plus patterns are calculated independently.
This is already included in our future roadmap. Additionally, as an option for lower-spec environments, we plan to introduce a setting that allows users to use static images as backgrounds instead of video BGAs.
The core appeal of PLATiNA :: LAB is completed not just by rhythm gameplay, but through interactions with the DBs. We are committed to actively introducing more content that allows you to engage and enjoy your time with the DBs in even more diverse ways.
We hope the information shared today helps clear up any questions you may have had and gives you plenty of exciting changes to look forward to. Moving forward, we will continue to release these Developer Notes as a platform for close communication, allowing us to review and refine our development process alongside your valuable feedback.
It's hard to believe 2026 is already moving so fast, with spring right around the corner. We ask for your continued support as PLATiNA :: LAB continues to evolve and grow, much like the vibrant new life that arrives with the spring season.
Sincerely, PLATiNA :: LAB Development Team

Optimized graphical performance to ensure smoother NOTE movement in high-frame-rate environments, such as 144Hz, 240Hz, and above.
In addition to the above, several issues encountered during gameplay have been resolved.
Fixed an issue where screen stuttering occurred during the first \ effect while playing a song.
Fixed an issue where SPEED could not be adjusted continuously by holding down the increase/decrease SPEED keys.
Fixed an issue where adjusting the SPEED at a specific timing immediately after a song ended caused the input to be processed repeatedly, resulting in the SPEED jumping to its maximum or minimum value.
Fixed an issue where key input effects from a previous session remained on screen if a RETRY was triggered while a key was being held down.
Fixed an issue where DB's Live2D model would appear with the "MISS" animation still active if the session was restarted immediately after a \ judgment.
Currently, our development team is prioritizing overall performance optimization and stability improvements, including the items mentioned above.
Detailed information regarding these efforts will be shared in next week’s 'Developer’s Notes.' We will continue to implement further improvements following this update.
Selecting content from a DLC you do not own will now directly open its Store page via the Steam Overlay. (Steam Version Only)
You can now check the Affinity Level and Points of your current DB directly on the Song Selection screen.
Fixed an issue where certain UI elements in the 'Radio' Device Skin appeared misaligned.
When multiple scrolling texts are displayed within a single UI element, they will now sync to scroll at the same timing.
Example: In the 'Play info widget' on the gameplay screen, if both the Song Title and Artist Name are long, their scroll effects will now trigger simultaneously.
When playing 〈MEGALOVANIA (Camellia Remix)〉, you will see the Song Title (MEGALOVANIA (Camellia Remix)) and Artist Name (Toby Fox (Remixed by Camellia)) scroll in perfect sync.
Fixed an issue where DB's Live2D motion displayed abnormally when switching pages using the \ key on the Result screen.
Fixed an issue where the mouse interaction area for the \ icon (top-right of the screen) did not match the actual visual icon area.
Fixed an issue where the Sound Effect setting titles (BASS BOOST, TREBLE BOOST, LIVE MODE) in the \ menu appeared blurry on PAUSE screen.
Fixed an issue in the English language setting where the button text for unobtained voices in the \ menu exceeded the UI area, and updated the text for clarity:
(Before) NOT ACQUIRED → (After) NOT OWNED
