Preheat oven to 375°F (190°C).
In a large bowl, combine peaches, sugar, and tapioca.
Line a 9-inch pie plate with one pie crust. Place pie filling in pastry.
Place the second crust on top of the peach filling. Press the edges together with the bottom crust. Trim the crust, leaving about ½ inch of crust around the edges. Flute the crust.
Make several slits in the top of the crust to allow steam to escape while baking. Lightly brush cream on the top and sprinkle white sugar, if desired.
Bake in preheated oven at 375°F (190°C) for 45-60 minutes.
Serve with ice cream if desired.
