This has been asked for and debated in some form since Valve introduced hibernation into the Source engine. The changes here are based on quite a deep dive into the engine's frame/think logic (mainly in CS:GO which has "legacy" hibernation and TF2 which has modern "frameless" ticking) and all seem to be sane. I think I've managed to maintain all the oddities around time keeping, and the simulated bool (even though we don't really use it for anything) should have a sane value. There is a slight behaviour change for anything needing exact timings as we're now run earlier in the frame before gpGlobals are updated, this should generally be fine but it might affect some plugins such as bhop timers that are trying to be extremely precise (often more precise than the underlying data they're using). We'll probably want to add a native for plugins to detect if the server is not completely simulating so they can opt out of work, but I think defaulting to having things work like this makes more sense than adding a 2nd set of per-frame forwards and natives (#540), and this makes timers and any extension callbacks work automatically.
