CS2 Fog Of War: Server-sided anti-wallhack occlusion culling for CS2 servers
Summary
CS2FOW is a server-side anti-wallhack plugin for Counter-Strike 2 that uses pre-baked BVH8 map data and AVX-accelerated visibility checks to decide which enemy entities to transmit to each client. It operates as a Metamod:Source plugin, performing offline or low-priority background baking to reduce live server load while limiting data leakage through visibility filtering. The project emphasizes compatibility with workshop maps and includes detailed configuration, build, and deployment guidance along with known limitations.
