PC STABLE UPDATE 1.01 ✅ fixes to persistence ✅ better server performance ✅ new weapons & scope ✅ improved voice chat ✅ 50+ other fixes and changes Best news? It’s out now!


New firearms

With each Platform Update, we're aiming to expand the variety of content available in the game. Our choice for 1.01 were two classic 7.62x39 rifles previously available in the legacy builds: the SK 59/66 and the CR-527, also supported by the re-introduction of the Hunting Scope!

SK 59/66

A ten-shot semi-automatic rifle fed from an internal magazine. It is an older model, but still reliable, using 7.62x39mm rounds. Can be equipped with a PU scope and an improvised suppressor.


A bolt-action hunting rifle, fed from a detachable magazine. It's light-weight and accurate when used at intermediate ranges. Uses 7.62x39mm rounds. Can be equipped with a Hunting Scope and an improvised suppressor.

Persistence fixes

Undesirable persistence wipes were definitely among the most annoying issues reported in 1.0. With 1.01, we're introducing a system of Persistence Backups that aims meant to

prevent problems with saving of the persistence data

on the servers.

This system will be available to both official and community owned server. We've seen some pretty good results on the Experimental branch so far. In any case, we will still be closely monitoring all incoming reports should any loot, bases, or other persistence data get deleted after server crashes/restarts.

Server Performance Optimizations

Good server performance is critical to ensure an enjoyable DayZ gameplay experience. In 1.01, our programmers have made some solid progress on that front. Official vanilla servers running at full capacity with 60 concurrent players should no longer be witnessing flying cars and other shenanigans on a regular basis.

As far as

community/modded servers go

, please understand that increased player counts may and other modifications to the server setup have a significant impact on the server performance, and

problems may occur


We will continue with further optimisations over the upcoming updates. The most curious of you can take a look at the report on this topic by our Lead Programmer, Mirek Maněna.

Voice communication improvements

The voice chat in 1.01 is using a completely new codec that bumps the overall quality of the Voice over Network sound - especially with a high quality microphone. We've also added a mumbling sound filter for players who try to communicate when their speech is restrained with a rag.

New status indicators & damage tweaks

As a first step towards balancing the health and damage systems, we've added new icon status indicators that better communicate bleeding damage and the effect of medication (for example, the vitamins will now boost your immune system).

We've also made some adjustments to the player damage, with the most visible example being the reintroduction of a bleeding damage penalty when walking barefoot. Furthermore, we removed the chance variable for bleeding damage dealt by bullets. Now, every bullet scratch causes bleeding 100 percent of the time.

TrackIR Support

TrackIR is a head tracking input device that allows you to use freelook independently from your mouse controls, and 1.01 now fully supports this input method. Popular and proven in Arma, introducing this input method was pretty straightforward for us, so we made that option available already. If you own TrackIR, you'll definitely have some fun when driving around in your ADA!

50+ other changes and tweaks

In addition to the highlights, we've introduced over 50 other changes and tweaks that make DayZ a better game. Read the full changelog below!
