Bug description

As on my screenshot, when playing on the new update (2023.605.0-lazer), the new score created (one of the bottom) is really lower than previous.

This is because lazer is now using a new scoring system, ScoreV2. Your old scores were set using a different scoring system.
You can find more information about the new scoring sytem at the lazer update video.

So is there a way to migrate my old scores to the new scoring system in the objective to see a personal progression ?
And if it's not possible (which would be a real shame), how to delete my local scores ?

I also found this

not really sure what this could be.

That's #23756.

ah, ok. 👍

Let's keep this issue for tracking the "old lazer score algorithm" problem, and use #23756 for the "scores imported from stable" problem.

how to delete my local scores ?

You can delete all scores using the maintenance button at the bottom of settings.

You can also delete per-beatmap:

Or per-score (right click):

The general consensus on the lazer (old) vs lazer (new) scoring seems to be that we should just let it be. It's going to be very hard to make any sense of trying to cross-compare the scores.

So I'd recommend deleting any scores that feel out of place to you.

Of note, we're going to hotfix osu!mania, where the difference in the two scoring algorithms was massive (#23816).
