DayZ 1.29 reached players in two steps. Update 1.29 itself went stable on all platforms on 8 April 2026, after a long experimental phase: it first went to Experimental in August 2025, was pulled back for more stability work and returned to Experimental on 19 February 2026. That release carried the server performance work. Road to Badlands came later as an extra update to 1.29, on Experimental from 1 July and stable on 15 July 2026. It kept the 1.29 number because Bohemia reserved 1.30 for the Badlands expansion, which launches 15 October 2026 (see our Badlands preview).
Road to Badlands is mostly content: the SCR-17 rifle with two buttstocks, Holo Sights, the T65 tanker helmet, military caps, desert camo versions of the combat backpack and plate carrier, woodland and desert Female Soldier Infected, and a Nasdara military convoy event with new wrecks on Chernarus and Livonia. Most of that is for players. What matters for admins is that the new items, the convoy event and a round of loot changes arrive through the vanilla mission files, which we come back to below.
The Real Headline: Server Performance
When 1.29 went back to Experimental in February, Bohemia wrote that the main performance problems on high-population servers came from the way the game handled physics and player data. It said its optimizations increased server performance by 400%: in heavy stress tests, servers that started at 9 FPS reached 50 FPS (Steam announcement, 19 February 2026). Those changes went live with the stable release on 8 April (Steam announcement, 8 April 2026), not with Road to Badlands in July.
The announcement does not say which change produced which part of the gain. The 1.29 stable change log lists "General server performance optimizations" and these two physics changes:
- "Enabled multithreading support for Bullet Physics library", so the physics engine can use more than one CPU thread
- "Inactive bodies no longer tick EOnSimulate/EOnPostSimulate", so physics objects at rest stop running those simulation events every tick
Treat 400% as a stress-test result, not a multiplier you will see on your own server. How much of it shows up depends on your population, your mods and your settings. A server that was CPU-bound on a busy Chernarus or Namalsk map before 1.29 should have more room now, whether you spend that on a smoother full server on the same hardware or on another mod or two.
What Else Changed for Admins
A few smaller changes in the 8 April notes are worth knowing, even though none of them require you to touch a config file:
- Player location is now written to the connection and disconnection logs, which gives you more context when you go through them
- Items on the ignore list no longer spawn when they are part of cfgspawnabletypes.xml or already sit in a player's inventory, so the loot restrictions you set should now hold
- Some weapons no longer spawn with incompatible attachments that caused errors, another loot accuracy fix rather than a new setting
None of these need action from you. They just mean the config you already wrote behaves closer to how you intended it to.
The Mod Compatibility Window
1.29 also changed systems that mods rely on. Its modding notes include an "Initial update of Animation System to Enfusion 2021" next to the physics changes above, and in February Bohemia warned that many mods and framework mods might not work properly at first. It asked server owners to review their dependencies with the mod authors while 1.29 was on Experimental. That window closed when 1.29 went stable on 8 April.
The next one is open now. Update 1.30 brings more animation changes, and when it went to Experimental on 16 September Bohemia warned modders that animation-related mods may run into problems (Steam announcement). It goes live together with Badlands on 15 October. Check every mod in your list for a 1.30 update before you update a live server. Our 1.30 server checklist walks through the rest.
Loot Changes in Road to Badlands
The central economy is where April and July differ. Bohemia kept the loot experiments it had tested on Experimental in 2025 out of 1.29 itself. With Road to Badlands it brought some of them to the live game: guns are placed with more intent, vests and helmets are rarer, and some items now spawn in new places, such as certain firearms around farms (Steam announcement, 15 July 2026). Bohemia hopes this slows the game down a little and puts more weight on resource management and on how you loot right after spawning.
Those changes live in the vanilla mission files. On 15 July Bohemia updated types.xml, cfgspawnabletypes.xml, events.xml and cfgignorelist.xml for Chernarus, Livonia and Sakhal in its Central Economy repository on GitHub. If you keep your edited files in a renamed mission folder, updating the server leaves them alone, so new items only spawn once you merge their entries into your types.xml. If you edited the files in the default dayzOffline folders instead, back them up before you update, because a server update can replace them with the new vanilla versions.
Before You Update
If you are running a live community:
- Back up your mission folder and persistence data before touching the server binary, same as any update
- Check every mod on the Workshop for an update made for the version you are installing rather than assuming compatibility
- Merge the new vanilla mission files into your own if you run edited types.xml or events.xml files
- Test on a staging copy first if you run a heavy modpack like Namalsk or a large Expansion setup, since animation and physics changes are exactly the kind of thing that surface in mods rather than vanilla
- Do not expect the FPS gain to show up instantly in a dashboard number, it is most visible under real population load, not on an empty test server
Bottom Line
The performance work came with 1.29 on 8 April. Bohemia reworked how the server handles physics and player data, its stress-test servers went from 9 to 50 FPS, and the change log adds multithreaded physics and less simulation work for objects at rest. Road to Badlands in July added Nasdara gear, a convoy event and loot changes, and a server with its own mission files only gets those after a merge. Next up is 1.30 with Badlands on 15 October, and that one needs a proper mod check before you update a live modded server.
