This topic was originally written when Infinity was initially released. Information in it might be woefully out of date.
Infinity is available for free on any tier now, includes population, and is the recommended mode to use with FiveM/OneSync. To use it, simply launch your server with +set onesync on.
Slot counts are still dependent on tier, see https://fivem.net/server-hosting for the latest info.
Original post
A while ago, the FiveM client/server got support for ‘Infinity’ mode for OneSync, which combines player entity culling, player culling and (hopefully temporary) removal of automatically-generated population.
This post seeks to quickly detail some commonly-asked questions.
What is OneSync: Infinity?
- A mode allowing (up to) 1024 players at this time. We have only tested 600-ish in load tests since we couldn’t get any more players, but it held up quite well in the end (on a server with minimal resources)
- To accomplish this, it uses the following technological changes:
- Removal of population to save object ID pool space. You can still create (some) synced/networked peds using script, however.
- Player ped/vehicle culling. No entities will be created on clients outside a ‘focus zone’, which currently is hardcoded to 300 units around a player. We’re still looking for a better algorithm.
- Player culling. No players will be created/deleted locally outside of the focus zone too. This means that all player iteration will have to happen server-side.
- It also has a bit better performance than ‘plain’ OneSync at this time due to player ped culling, and works around the so-called ‘head blend bug’.
What are the gotchas?
- A new common crash:
kilo-xray-tango. It’s quite rare depending on how densely packed players are, figuring out a consistent repro would be very welcomed! - Automatic population is disabled as otherwise you’d run out of object IDs around 200-300 players. (a global maximum of 8192 spawned entities exists at this time)
- You need a Platinum subscription, or a ‘manually granted Infinity’ group membership at this time. Once it’s developed further, we may consider allowing tiered player caps for lower Patreon subscriber tiers.
- A number of scripts will need changing. Admin menus, ‘teleport to player’ UI and scoreboards definitely won’t work directly. Loops are still up to 256 max (or using GET_ACTIVE_PLAYERS), but will only find nearby players.
How do I use it?
- Add
+set onesync onto your server startup command line - it won’t work if you add it in the .cfg. - Make sure
onesync_enabledandsv_maxclientsare set appropriately. - Fix scripts that end up showing incomplete lists.
Support FAQ
Everyone’s instanced, I only see myself?
That’s supposed to happen. Get closer to other players, and fix your player listing scripts.
How do I get all players on the client?
Not at this time, we’re still investigating efficient ways to send this data along. Currently, you should use server/latent server events for this.
We expect people to release a few helpful helpers in the #development:releases section for this.
Why is X built-in feature showing an incomplete list?
Report it! #general-discussion:1s-reports
Why is this paid? 
It just is. This might change after the Commerce release.
?
Yes, !
