FPS on Atlas. Tune your game.
Low FPS or delayed actions on Atlas: distinguish computer performance from connection issues, check graphics settings and keep the server pack compatible.
The essentials. Step by step.
Identify whether the image stutters or actions are delayed.
Reduce render distance and compare in the same place.
If the issue remains, tell support the settings and location.
Separate FPS from delayed actions
If the image stutters, start with graphics settings and computer load. If the camera moves smoothly but actions confirm late, check your connection and server status. A densely built town may perform differently from open terrain on the Earth map.
Change one setting at a time
Close unnecessary heavy apps and reduce render distance. Compare results in the same place, then try simpler graphics settings. Compare one settlement street and one area outside town, keeping the settings unchanged between repeat checks.
Keep the pack compatible
Avoid adding random optimisation mods or removing required server mods to gain FPS. Check compatibility with the published Atlas pack. For memory, use available Maralys settings and server requirements; one fixed number of gigabytes does not suit every computer.

A couple more answers.
How much memory should I allocate?
Use the published pack requirements and your computer’s resources. Leave memory for the system and other apps instead of allocating all RAM to the game.
FPS is high but breaking blocks is delayed?
Connection latency or server processing may cause this. Check server status and try again; describe a repeatable problem to support.
