Two clients, two launchers, one very split playerbase. A straight comparison of what changes between FiveM Legacy and FiveM Enhanced — and which one you should be on.
Since 21 July 2026 there are two versions of FiveM. They are not interchangeable, they don't talk to each other, and choosing between them has real consequences for both players and server owners.
Here's the straight comparison.
FiveM Legacy runs on the original GTA V PC build. FiveM Enhanced runs on GTA V Enhanced, the upgraded build Rockstar shipped on 4 March 2025.
They exist as separate clients with separate launchers. Cfx.re has said it intends to unify them into a single ecosystem later, but that isn't the situation today. Enhanced does not replace Legacy — Legacy servers keep running unchanged, and no one is being forced to move.
The critical rule: a Legacy client cannot join an Enhanced server, and an Enhanced client cannot join a Legacy server. There is no cross-play.
| Area | FiveM Legacy | FiveM Enhanced |
|---|---|---|
| Base game | GTA V (original PC build) | GTA V Enhanced |
| Availability | Fully public | Early access, server owners first |
| Sync rate | 30–40 Hz | Up to 120 Hz |
| Server RAM per player | Baseline | Up to 50% less |
| Sync modes | Multiple, including lower-capacity legacy modes | High-performance mode only |
| Max players | Up to 2,048 | Up to 2,048 (higher in future testing) |
| Connection protocol | UDP | WebSocket for initial connection |
| Voice | Mumble VoIP | Rebuilt system, Mumble replaced |
| Lua / JS / C# scripts | Native | Backward compatible |
| Custom assets | Native | Require conversion via Alchemist |
| Asset Escrow | Supported | Not at early access launch |
| Visuals | Original renderer | Ray tracing, modern rendering pipeline |
The rebuilt OneSync is the real story. At equivalent player counts, servers use less bandwidth, less CPU and less memory, and players see more stable frame rates and lower latency. The improvement scales with player count — a 40-slot server won't notice much, a 300-slot RP server absolutely will.
The 120 Hz sync rate against Legacy's 30–40 Hz is the change most likely to be felt in actual gameplay. Tighter sync means fewer of the rubber-banding and desync artefacts that plague busy servers during pursuits and firefights.
Bullet impact precision and dead body synchronisation between clients have both been properly fixed. Both previously needed server-side workarounds. If you've been maintaining patches for these, Enhanced makes them redundant.
Initial connections move from UDP to a WebSocket-based protocol, improving resistance at the connection layer. For owners who've been paying for mitigation, this is a genuine cost consideration.
Ray tracing and the modern rendering pipeline come across from the Enhanced build. Worth being realistic here: most roleplay servers run heavy graphics packs anyway, and a well-configured Legacy server with a good ENB is not obviously worse-looking to a casual eye.
The entire established roleplay ecosystem is on Legacy. Every large community, every mature server, every player you want to roleplay with. Migrating early means migrating away from your playerbase.
This is the blocker. Escrow is how paid FiveM resources are protected, and it isn't supported on Enhanced at early access launch. If your server runs paid scripts or paid vehicle packs — and virtually every serious server does — you cannot fully migrate yet. Cfx.re has said more details on escrowed asset conversion are coming.
Years of Legacy-format custom assets exist. Converting them isn't automatic, and a working Legacy resource is not automatically a working Enhanced resource.
Scripts do. Existing Lua, JavaScript and C# resources continue to work without modification, along with the FiveM natives they call. C# and JS developers additionally get more modern runtime environments than Legacy offered.
Assets don't. Custom models built for Legacy are not natively compatible with Enhanced. Cfx.re's conversion tool, Alchemist, handles YDR, YTD, YFT, YPT and YDD formats. See our Alchemist conversion guide for the workflow.
Players: Legacy. There's no meaningful choice yet — general access to Enhanced isn't open and there's nowhere to play.
New or small server owners: worth testing Enhanced seriously. You have fewer escrowed dependencies to untangle, and early presence on Enhanced is a differentiator that gets harder to claim every week.
Established server owners: test on a parallel instance, don't touch production. Wait for Asset Escrow. The performance gains are real but they don't outweigh breaking a working community.
