Claude's long responses now render about 4x smoother on web and desktop
Questions this post answers
Why did Claude's web and desktop app used to stutter on long responses?
The old streaming renderer redrew the entire response every time new text arrived, instead of updating only the parts still changing. Anthropic rebuilt the renderer to touch only the actively changing portions, which cut stalls on slower laptops by 9 times and shortened the worst freeze by 4.5 times, while letting 120Hz MacBooks hold a full 120fps throughout a response.

How much faster does Claude's app render long responses after the streaming renderer rebuild?
Long replies stall 9 times less often on slower laptops, and the longest freeze is 4.5 times shorter than before the rebuild. On a 120Hz MacBook, the app now maintains a full 120fps from the first token to the last, a change owed to redrawing only the actively updating text rather than the entire response.
