Same figures for me:
- Convenience store: 2.7km
- Supermarket: 2.5km
- Bus stop: 4.2km (this may be incorrect I think there was a closer one that didn’t show on the map)
- Park: 6.2km
- Big Supermarket: 3.5km
- Library: 6km
- Train station: 7.9km
- Hart Plaza(nowhere really analogous to big Ben around me): 46km
Shaders are typically code run on the GPU to make your game look good. They power lighting and various effects used in rendering the game. Virtually everything uses shaders, and precompiling them can save a lot of resources over having to compute them on the fly, but comes with associated hassles.
