The NPCs on the top are technically just props with an animation (like the crowd in Alesso). I don't believe they count.

I see. So much for that theory; I'd love to be able to nail down a cause for these persistent performance issues.

It's a rather silly issue anyway that can be fixed by commenting out the break statement below. I've also noticed that the detection calls are queued in 2 s intervals instead of the 1 s from since the last time I checked (some update <50). So even without the swamped queue, unaware NPCs essentially open their eyes once every 2 s and are blind for the remaining time. Only if they notice something interesting they will check every 0.1 s. That's plenty of time to do some crazy stuff. But there is no way to tell when they are blind and when they are not. And all cameras still check every 0.1 s no matter what.

I see, that explains all the irregular behavior! Thank you!

Would you mind if I include that fix in a generic fixmod (fully credited of course)?

I would not. But I think SC has mentioned that the VR beta has this part more or less fixed. So it might not be necessary to comment out that break. The delays of 2 s between checks on the other hand are probably unchanged. Cannot be bothered to check right now.

Hmmm, yeah, I see the break is added to another requirement in enemymanager for the VR-beta. But considering that's not expected to go live till 2018, it'll be a good fix till then.

Fairly sure the 2s thing was still there last I checked.

It's just so ridiculous considering that cameras check every 0.1 s. If performance with lots of enemies was an issue, they could make a check every 0.1 s when the alarm has not gone off and 2 s or whatever time afterwards (it does not matter much at that point anyway). But they have never cared about performance or they would not have ramped up the max enemy count several times throughout the years.
