In a medium bowl, combine the graham cracker crumbs, sugar, and melted butter until evenly moistened.
Press the mixture firmly into the bottom of a 9-inch springform pan, creating an even crust.
Refrigerate the crust while preparing the filling.
In a large mixing bowl, beat the softened cream cheese with the sugar until smooth and creamy.
Mix in the vanilla extract.
Gently fold the whipped heavy cream into the cream cheese mixture until light and fluffy.
Pour the filling over the chilled crust and spread evenly with a spatula.
Refrigerate the No Bake Peach Blueberry Cheesecake for at least 4 hours, preferably overnight, until fully set.
Before serving, decorate with fresh peach slices, blueberries, and drizzle generously with the mixed peach and blueberry sauce.
Slice and serve chilled.
