... it doesn't matter what CPU you're using, lol. I've tried starting a Rust server on a freshly installed Windows Server 2016, only to see that it will still use 100% of the CPU on 32 cores. 8 cores, 16 cores, 32 cores - it's all the same. I've tried with various CPUs, both Intel and AMD. It's always the same. It does however generate faster on better CPUs but that doesn't solve anything since even 1 second of lag is enough to ruin a round in CSGO and other competitive games. Depending on the load on our machines, navmesh takes around 10-15 seconds to generate.
I've tried to script my way out of it but haven't found a solution for it yet.
