If Arkheim – Realms at War is slow for you, please check if your browser’s hardware acceleration is activated. Without hardware acceleration, the game will react slower than usual.

For some players, switching to a different browser helps to solve this problem.

If this doesn’t help, it is possible that you don’t fulfil the hardware requirements to run the game in the browser. We recommend that you download our client version here: https://www.arkheim.com/en/download

You can check your FPS (frames per seconds) in the settings, next to the video settings headline – please include this information if you contact support.
