How Much RAM Does a ModernCraft (Distant Horizons) Server Need?
ModernCraft (Distant Horizons) is a visually-focused Fabric pack for 1.21.1 built around Distant Horizons and Iris Shaders — see the ModernCraft (Distant Horizons) pack page for the full details. Its RAM needs come almost entirely from Distant Horizons' extended LOD chunk rendering rather than from heavy mods, since the rest of the pack is intentionally minimal.

6 GB
Bare minimum for solo play or a tiny group. It can run, but Distant Horizons' LOD chunk rendering leaves very little headroom, so expect it to feel tight once you move around much.
8 GB
The best starting point for most servers running this pack. This matches the pack's own recommended floor — it's sized specifically for Distant Horizons generating and holding LOD data far beyond vanilla render distance, not for heavy mods, since the rest of the pack is intentionally light.
10 GB
A safer buffer for a mid-size, active group exploring regularly. More players moving around means more LOD chunks being generated and held at once.
12 GB
Recommended for 10+ players or a long-running world with a lot of explored terrain. The LOD cache only grows as more of the map gets rendered, so a world that's been running for a while benefits from the extra room.
