There isn't any big change in performance. The measure rise time is longer but it's a bit of an artefact of the output shape.

There is a bit of a slow down right before hitting 80% and so that makes the measure point be almost twice as long ... I'd need to check if that's also in simulation. Could be non-linear capacitance/load on the line from the RP2350 chip being on that line.
I think it's an artefact of the board layout, there is a small stuf to go to a 7 seg display and I think it's some reflection. Probing another pin that doesn't go to the 7 seg doesn't show that hump and has a better looking rise time.
