Backface culling has been common since the late 1990s when we started using face normals to determine lighting rather than per-vertex lighting. Pretty much every 3D game engine since about 2004 has included and enabled it by default. How is it that you made a game that doesn't use it?

PVS isn't that expensive to compute. Especially nowadays. I assume this is actually referring to the binary space partitioning techniques used in DOOM and improved in Quake, Half-Life, etc in the late 90s, early 2000s.

The BSP tree was also extremely useful for optimizing netcode for games like Quake 3 Arena and games within that family and time period I believe.
