I should add, there was a software update waiting to be installed in the background, after it the lag resolved in the new Blender file. However, in a medium-heavy file (~500k points) the same kind of eraser lag still occurs, where the drawing is still smooth, but the eraser has a delay. Anyway, I'll leave it there since it's a separate issue.

Windows 10. Windows Ink enabled.
Not sure if this is related, but I was testing the eraser recently and noticed the same kind of input delay with all eraser brushes, except this is in a new empty file (Blender 3.0, 2.93). Drawing has no visible lag (excluding heavy files), but you can immediately tell eraser has a delay if you swipe quickly. Also, tablet input responds faster than mouse input (at 1000 polling rate).
