Onyx

The window to join Onyx is 02:00–06:00 UTC, when it averages 3 concurrent players — well clear of its 2-player round-the-clock average. It bites hardest at 02:00 UTC, averaging 5. Outside it the city empties: across 13:00–02:00 UTC it averages just 1 player, bottoming out at 19:00 UTC on 0, so an off-peak login means an all-but-empty server.

Capacity is a real constraint here: against 64 slots its peak this week hit 45 — 70% of the server — and when anyone is on it, it averages 4 players, which is 7% full. It is thinning, though: it averaged 1 players across 18 Jul–20 Jul, down 92% on the 9 it averaged across 14 Jul–16 Jul.

That puts Onyx ahead of 96% of the 42,220 FiveM servers ViceHub tracked consistently this week, ranked on peak concurrent players. That is measured from our own five-minute checks, not from anything the server claims about itself.
