GTA 6 Server Bandwidth Requirements
Bandwidth sits at the bottom of most hosting discussions because hosts call their plans "unmetered" and owners assume the problem is solved. It is not. Here is what a GTA 6 server likely uses and how to plan for it.
Why GTA 6 bandwidth will look like GTA 5
GTA 6 is not out, so exact numbers are unknown. But the client-server pattern is well-understood: positional updates, entity replication, script events, voice passthrough. The engine will improve, but the order-of-magnitude usage per player will be similar to GTA 5 FiveM.
On FiveM today, a realistic figure is 15 to 30 KB per second per active player, bi-directional, during normal play. Peaks hit 50 to 80 KB per second during chaotic moments (chases, shootouts, big crowds).
Monthly totals, back of envelope
- 32 slots, busy weekend schedule. 32 players × 25 KB/s × 3600 s × 10 hours per day × 30 days = about 850 GB per month inbound plus outbound. Round up: 1.5 to 2 TB per month.
- 64 slots, busy schedule. 3 to 5 TB per month.
- 128 slots, consistently full on peak hours. 6 to 10 TB per month.
- 256 slots, heavy RP city. 12 to 20 TB per month.
These are rough. Your number depends on script chattiness, voice setup, and how full the server actually sits. A 64-slot server that averages 25 players will use less than one that runs at cap.
Peak rate planning
Average is not what kills you. Peak is. A 64-slot GTA 6 server with a full city chase scene can spike to 6 to 10 Mbps briefly. You need at least 1 Gbps unshared on the NIC to absorb these comfortably.
This is one reason to pick hosts that explicitly provide 1Gbps or 10Gbps per port with documented peering. Our host reviews include peak-capable hosts.
The "unmetered" trap
Most hosts' unmetered plans have fair-use clauses. Typical thresholds:
- Budget hosts: 3 to 5 TB per month.
- Mid-tier hosts: 10 TB per month.
- Premium hosts: 20 to 50 TB per month or truly unlimited.
If your server consistently blows past 5 TB and you are on a budget plan, you will either pay overage fees or have your network throttled. Neither is what you want on a Saturday night.
How to reduce bandwidth
- Tune sync update rates. Most frameworks have tunables for position sync frequency. Lower frequency for non-critical entities.
- Reduce entity count. Fewer NPCs and spawned props mean less replication.
- Use scene streaming correctly. Poorly set streaming distances replicate entities to clients that cannot even see them.
- Move voice off-server. Use dedicated voice infrastructure (Mumble, TeamSpeak, or Discord) instead of in-game voice when possible.
What to ask a host before signing
- What is the actual monthly bandwidth cap, including fair use?
- What is the per-port speed (1Gbps? 10Gbps?)
- What happens if I exceed the cap? Overage rate, throttling, or billing?
- What is the 95th percentile model, if any? Some hosts bill on 95p instead of total.

Frequently Asked Questions
How much bandwidth does a GTA 6 server use per player?
Expected 15 to 30 KB per second per active player in normal play, peaking at 50 to 80 KB per second during chaos. Matches GTA 5 FiveM figures, which is the best available baseline.
Is 1 Gbps enough for a GTA 6 server?
Plenty for under 256 players. The headline number matters less than whether your host oversubscribes it. Ask for 95th percentile data from your host.
What happens if I exceed my bandwidth cap?
Depends on the host: overage fees, speed throttling, or a stern email. Check before signing. Overages are one of the biggest surprise bills for new server owners.
