Latest DayZ update improves server performance

Posted by: Travis at 2/6/2014 11:30 AM

Dean Hall and his team behind survival zombie game DayZ have released a new game update along with a complete changelog. The new update contains further engine optimizations and a range of smaller bug fixes, all of which are leading to a smoother experience on servers. With the newest update, servers are said to gain a boost of around 5-10 FPS. Once the game has been further optimized, future updates will be able to increase the player and zombie counts in addition to the enabling of loot and zombie respawns.

The complete patch changelog can be found after the break. DayZ is available now for Windows PC through the Steam Early Access program.



DAYZ PATCH UPDATE 5 FEBRUARY 2014

Branch: Stable

ETA: Complete

Version: 0.33.114926

This build continues with small bugfixes and several engine changes. A late addition of a significant change to the server variable processing has provided us a major performance boost on the server of around 5-10 FPS. This helps with a great deal of issues and results in a much smoother game experience from players even on a smooth server. Once several more of these optimizations are made it will allow us to increase player/zombie numbers and enable loot and zombie respawning.
