Gameplay differences in osu!(lazer) 442s5g

For a comparative list of features between lazer and stable, see Help centre/Upgrading to lazer § Feature comparison 4i396j

This page documents differences affecting gameplay in osu!(lazer).

General 6285k

The Easy mod no longer pauses gameplay when recovering from failure 573z72

Instead of pausing gameplay while filling up the health bar, health is restored immediately.

Differences in grading systems 703071

In stable, the accuracy (and judgement) requirements for each grade are as follows:

Meanwhile, osu!(lazer) has these accuracy cutoffs now:

Hit window edge calculations do not match stable 7323s

When a hit lands right at the edge of the hit window, a different judgement may be given depending on the client version.

Differences in scoring 3s1b3u

Scoring in lazer will use a system similar to ScoreV2, with all ScoreV1 scores converted into the new system.

There are two interchangeable display modes for scores: standardised and classic. Standardised scoring limits score to a maximum of 1,000,000 points + bonus and score multipliers (similarly to ScoreV2), while classic scoring is the same as standardised, but scaled quadratically with the amount of hit objects in a beatmap (similar to ScoreV1). These can be selected from the settings, with all places where score is displayed in-game changing accordingly.

There are also some differences in how much score each hit object and each judgement is responsible for relative to each other.

Storyboard triggers are not implemented 2p2i5e

Some storyboards feature elements that react to player input or health.

osu! 62m3q

Notelock has been adjusted to be more lenient 463c2o

Recovering from a miss in dense patterns has been made easier.

Slider head circles require accuracy when hitting 4d54b

Until lazer, sliders have only required the accuracy of a 50/MEH judgement to reward a perfect score. This was done for historic reasons, but feels bad for a rhythm game. Going forward, sliders will require hit accuracy for their initial click.

Slider heads are more lenient 6n6t33

When clicking a slider early, the follow circle will now immediately start in a tracking state even if the cursor leaves the slider ball before the slider starts.

Additionally, when clicking a slider late, any ticks or repeats that have already ed will be judged as completed.

See this YouTube video for a detailed explanation.

Slider end leniency is now more lenient 1k4y6u

On very fast sliders, you now only need to be tracking somewhere in the last 36 ms, rather than at the point 36 ms before the slider end.

See this YouTube video for a detailed explanation.

Missing a slider head causes a miss 106a2b

Missing a slider head (either by not hitting it or hitting it during its miss window) would previously break combo but not cause a MISS judgement, and a judgement could still be received for the missed slider by completing the rest of it. This allowed players to get scores with low max combo while technically having no misses.

In lazer, not hitting the slider head will give a MISS judgement for the whole slider. After missing a slider head, combo, score, and accuracy can still be gained from slider ticks, repeats, and ends.

Slider ends do not cause hitsounds when not hit 31424m

In stable, slider ends would play their hitsounds even if they were missed, as long as any part of the slider was hit. This has been changed such that hitsounds match inputs 1:1.

The spinner spin speed cap of 477 RPM has been removed 3p4f5w

Instead of a speed cap, spinners now have a score cap determined by the total amount of rotations that can be achieved by spinning the entire spinner at a certain RPM depending on OD.

This means that the maximum score can be obtained early by spinning faster, with no more points awarded afterwards for the rest of the spinner duration.

The RPM required to get the maximum score is as follows:

Aspire-like glitched sliders are not ed z6g1x

Some adventurous beatmaps exploit glitches in the stable client that allowed for very weird slider mechanics. These range from zero-length sliders acting as invisible circles, to cross-screen stretched and squished sliders.

More discussion and consideration will be needed for how much of Aspire beatmaps will be compatible going forward. For example, invisible circles might become a properly ed feature in the future.

osu!taiko 45241u

Notes that overlap swells cannot be hit 6d518

Some gimmick maps make use of notes that overlap swells.

Drumrolls do not prevent mashing 5t2e3n

In stable, drumrolls could not be hit too quickly or too slowly. This restriction has been lifted, just like in ScoreV2.

The Flashlight centre is aligned with the hit receptor 1wd3h

In stable, the Flashlight centre is offset a bit down and to the right, making more hit objects visible.

osu!catch 4918

Hyperdash generation can be different in some cases 1h610

This may lead to inaccurate judgements in replays and increased difficulty.

Juice stream generation can be different in some cases 44z5

This may lead to inaccurate judgements in replays.

osu!mania p5l2v

Hold note heads and tails give judgements 5l5a

This functions similarly to ScoreV2 in stable.

Hold note ticks are removed 4o3x5x

In stable, hold notes give combo every 100 ms, while in lazer "hold note ticks" gave combo every tick interval.

None of those exist in lazer, meaning hold notes only give combo for the start and the end. However, just like in stable, combos break immediately when letting go of sliders.

Extreme scroll speeds are limited 6x4n44

Some beatmaps with SV gimmicks like teleports or stops do not look as intended, but are otherwise playable.

The PERFECT judgement hit window scales with OD 6k1v7

This used to be a constant ±16 ms regardless of overall difficulty.

Converts no longer have different hit windows 704c67

In stable, beatmaps converted from the osu! game mode into osu!mania had different hit windows.

The Flashlight mod does not have a gradient 12r1n
