This guide will show you how to troubleshoot ARK Server Lag.
Server lag is one of the most common and most frustrating issues ARK: Survival Ascended and ARK: Survival Evolved players encounter. Whether it shows up as rubber‑banding, delayed actions, slow world loading, or sudden performance drops during combat, lag can quickly turn a smooth session into an unplayable experience. Because ARK is a resource‑heavy game with complex world simulation, even small configuration issues or hardware bottlenecks can create noticeable latency. This ARK Server Lag Troubleshooting Guide is designed to help you identify what type of lag you’re dealing with, understand the underlying causes, and apply targeted fixes. Instead of guessing, you’ll learn how to diagnose performance problems step‑by‑step, covering server hardware, network conditions, game settings, mod behavior, save‑file bloat, and common misconfigurations that impact stability. By the end of this guide, you’ll have a clear workflow for isolating lag sources and optimizing your ARK server for smoother gameplay, better responsiveness, and improved long‑term performance.
Fixing Lag on My ARK Server
The vast majority of lag issues our clients encounter stem from either mod behavior or server configuration settings.
Configuration Files
Having multiple entries for the same setting in your configuration files is a known cause of server lag. This issue is most commonly seen with the autosave setting, but duplicate lines can affect other settings as well. Always ensure that each configuration option appears only once in your config files.
Your autosave interval also plays a role in performance. Setting the autosave period too low (shorter intervals) forces the server to save more frequently, which can introduce noticeable lag. We recommend leaving it at the default 15 minutes or increasing it, then simply performing a manual save through RCON during restarts or updates.
Increasing your DinoCountMultiplier will negatively impact performance. The server must simulate and manage a significantly larger number of creatures, which increases CPU load and can also reduce client frame rates. Be mindful of how higher multipliers affect both server stability and player experience.
Finally, avoid setting any multipliers to excessively high values. Extreme configurations can degrade performance across the board and lead to unpredictable server behavior.
Mods
Several mods are known to cause performance issues on ARK servers. If your server is running mods, the first step we recommend is temporarily removing them, along with the saved data for testing purposes, to determine whether the performance problems persist without them.
It’s also important to review the mods you’re using to ensure they are compatible with the latest version of ARK and that there are no reports of bugs or performance issues. Mod developers often disclose known problems, so checking recent feedback can help you identify potential troublemakers.
Additionally, verify that your mods are compatible with one another. Not all mods work well together, and conflicts can easily lead to instability or errors. For example, running two mods that both modify the same dinosaur can cause overlapping edits, resulting in crashes, lag, or corrupted data.
