GTA 6 Server Bandwidth Requirements

Editorial Team·March 30, 2026·6 min read

Bandwidth is typically at the bottom of most hosting discussions because hosts advertise "unmetered" plans and owners think the issue is taken care of. It's not. Here is approximately what a GTA 6 server will likely use and how to budget for it.

Why GTA 6 bandwidth will look like GTA 5

GTA 6 isn't here yet, so exact numbers are unknown, but we know what the client-server model replicates: positions, entity states, script events, voice passthrough. Granted, the engine will advance, but per-player bandwidth use will probably be the same order of magnitude as GTA 5 FiveM is today.

On FiveM today, realistic bandwidth usage is 15 to 30 KB per second per active player, bi-directional, while just playing. It will spike up to 50 to 80 KB per second during intense scenarios (pursuits, gunfights, large crowds).

Monthly totals, back of envelope

32 slots, busy weekend schedule. 32 users × 25 KB/s × 3600 s × 10 hours per day × 30 days = roughly 850 GB of inbound traffic plus outbound traffic per month. Round it up to 1.5 to 2 TB per month.
64 slots, busy schedule. 3 to 5 TB of traffic per month.
128 slots, consistently full on peak hours. 6 to 10 TB of traffic per month.
256 slots, heavy RP city. 12 to 20 TB per month.

These are approximate. Depending on how chatty your scripts are, your voice setup, and how full your server actually is, you'll use more or less. A 64-slot server that averages 25 players will use less bandwidth than one running at full capacity.

Peak rate planning

Peak, not average, is what kills you. A 64-slot GTA 6 server with a full city chase can spike to 6-10 Mbps for a moment. You need at least 1 Gbps, unshared on the NIC, to handle that comfortably.

This is one reason you want to choose hosts that specifically offer 1Gbps or 10Gbps per port with documented peering. You can find peak-capable hosts in our host reviews.

The "unmetered" trap

Unmetered plans on most hosts contain fair-use policies. Common caps:

Economy hosts: 3-5 TB/month.
Mid-tier hosts: 10 TB/month.
Higher-end hosts: 20-50 TB/month or genuinely unlimited.

If your server regularly exceeds 5 TB and you are on a budget plan, you'll either incur overage charges or your network will be throttled. Neither option sounds ideal on a Saturday night.

How to reduce bandwidth

Adjust sync update rates. Most frameworks allow you to tune how frequently positions are synced. Decrease the rate for non-critical entities.
Shrink entity count. Fewer NPCs and spawned props will reduce replication.
Use scene streaming properly. When set up wrong, streaming distances cause unnecessary replication of entities that the client can't even see.
Move voice off-server. Use Mumble/TeamSpeak/Discord or another dedicated voice platform instead of in-game voice whenever possible.

What to ask a host before signing

Exactly how much bandwidth is in the monthly cap, including fair use?
How fast is each port: 1Gbps or 10Gbps?
What happens if I go over the cap? Overage rate, throttling, or billing?
Is there a 95th percentile model in place? Some hosts bill their traffic on 95p instead of aggregate.

Frequently Asked Questions

How much bandwidth does a GTA 6 server use per player?

Predicted 15-30 KB/s per active player under normal conditions, with bursts up to 50-80 KB/s when things get chaotic. The data roughly matches figures from GTA 5 FiveM, currently the best available baseline.

Is 1 Gbps enough for a GTA 6 server?

Plenty for fewer than 256 players. The advertised number is less important than whether your host oversubscribes it. Request 95th percentile data from your host.

What happens if I exceed my bandwidth cap?

Depends on the host: it either charges overage fees, throttles your speed or sends you a strongly worded email. Read the fine print before you sign up. Overage fees are one of the largest unexpected bills new server owners get hit with.
