The latest unstable builds add native AI traffic spawning, synced traffic lights, and smarter traffic simulation around nearby players, while the launcher now handles more required mods with less friction. For anyone following Cyberpunk 2077 multiplayer, this is the kind of update that makes Night City feel more like a living online world instead of a tech demo. ## AI traffic is starting to make Night City feel alive The headline change is AI traffic. Vehicles can now spawn through the game’s native traffic systems, which is a big deal for the feel of the city. Instead of relying only on players to create motion on the roads, the world can now begin filling itself out in a more natural way. That matters because traffic is not just decoration in a Cyberpunk 2077 multiplayer mod. Traffic helps sell scale, density, and atmosphere. Night City without moving vehicles can feel empty very quickly. Even an early version of shared traffic goes a long way toward making the city feel inhabited. This does not mean the system is “finished.” It means the foundation is getting real. Native spawning is the kind of milestone that opens the door to better behavior, better performance tuning, and more believable streets over time. ## Smarter traffic simulation near real players Another important change is how traffic simulation is handled around players. The new build uses a nearest-owner approach for simulation, which means the traffic around a given area is tied more directly to the closest player. For players, the practical result is simple: nearby traffic should behave more consistently where it matters most. In a CP2077 multiplayer environment, the biggest challenge is not just making cars exist. It is making them feel stable and shared when multiple people are nearby. Focusing simulation around the nearest player is a sensible step toward that goal. For future server owners, this is also encouraging because it shows the team is working on the hard part of a Cyberpunk 2077 dedicated server experience: deciding what gets simulated, where, and for whom, without wasting resources on parts of the city nobody is currently using. ## Synced traffic lights make intersections feel shared Traffic lights are now synced too. That sounds small until you imagine two players approaching the same intersection and seeing different light states. In any Cyberpunk 2077 online world, mismatched city systems break immersion fast. Shared traffic lights make intersections feel like part of one consistent city. They also support future roleplay and driving scenarios, especially for a Cyberpunk 2077 RP server where street-level behavior matters more than flashy one-off moments. This is one of those changes that players may not always call out directly, but they absolutely feel it when it is missing. ## Better TV screen rendering for immersion Today also included a visual polish fix: TV pictures now render in perspective and sit behind objects that should appear in front of them. That improves scene depth and makes screens feel like part of the world instead of an overlay pasted into it. It is not the loudest feature in the patch, but visual correctness matters in Night City. Small rendering fixes add up, especially in a world full of screens, signage, and dense interior spaces. ## Launcher improvements for custom server setup The launcher also got a very practical upgrade. It now accepts hash-verified mods hosted on regular public HTTP servers, and it can install required AudioXL, Audioware, and wrapped mods. For players, that should mean fewer setup headaches when joining servers with custom requirements. For server owners, it opens up a more flexible way to distribute approved content without adding unnecessary friction. This is one of the less glamorous parts of building Cyberpunk 2077 co-op and server-based play, but it is essential. A multiplayer mod lives or dies on the join experience. If installing required content is confusing or fragile, players bounce before the fun starts. Every improvement here makes OPEN//77 more usable in the real world. ## New unstable builds are out now These changes were rolled into fresh unstable releases for the client, server, and launcher, with the current traffic work also deployed in Germany. As always, unstable builds are where the team moves fast, tests major systems, and gets the foundations ready for the larger playable future. Today’s update is exciting because it improves both sides of the project at once: the city feels more alive, and the path into modded servers gets easier. For a Cyberpunk 2077 multiplayer mod, that is exactly the kind of progress worth watching. --- ## About OPEN//77 [OPEN//77](https://open2077.net) is a free, in-development **multiplayer mod for Cyberpunk 2077**: play online with other players in Night City on community-hosted **dedicated servers**, with synced combat, vehicles and world state, an account-backed launcher, and Lua-scriptable servers for co-op, freeroam and RP.
