Bug description

I launched osu!lazer to play the Daily Challenge. The Daily Challenge has EZ, AD and DP mods. The Daily Challenge was the first map I played in the session. I played two full attempts without any retries in between.
The first attempt had smooth performance at around 120 FPS average in the first half, then it started fluctuating between 120, 90 and sometimes 70 FPS in the second half.
The second attempt started a lot worse, with 70-80 FPS average in the first half, and then it became really bad in the second half: 50-60 FPS average with drops up to 30-40 FPS. This second attempt performance persists for all the latter attempts.

I can't see any obvious memory leak from a glance at the code.

• Given you're playing on a laptop, is it possible you're thermal throttling?
• How does the osu! process memory usage look like?
