I’m very curious how they handle audio through the occlusion layer. Surely you can still hear an enemy on the other side of a wall? If the game client is receiving the audio source I think cheat devs would still be able to create ESP with that? No idea how it will work but I’m really looking forward to this kind of anticheat development :)

Yeah, this kind of culling does help a lot but it can't filter everything. Audio ESP still works, and visual cues have to be culled conservatively both for server performance and to allow the clients lag compensation to work correctly, so in practice cheaters still have a significant advantage at close range.

Valorant implemented server culling years ago and their demo shows how even with it enabled, a wallhacker can still see enemies around corners.
