Moon Sweepers Best PC Settings: Fix Stuttering, FPS Drops & Crashes

While Moon Sweepers features a stylized sci-fi aesthetic, rendering millions of individual lunar dust particles, dynamic vehicle headlight shadows, and sprawling automated conveyor lines can tax mid-range PC hardware. If you encounter frame rate drops, micro-stutters, or base loading freezes, applying these verified optimizations will restore smooth 60+ FPS gameplay.

For building efficient, lag-free factories, check our base building guide and read the automation guide for conveyor routing strategies.

How to Apply the DirectX 11 Launch Option

Forcing DirectX 11 provides immediate frame time consistency across NVIDIA GeForce, AMD Radeon, and Intel Arc graphics cards:

1. Open your Steam Client and go to your Library.
2. Right-click on Moon Sweepers and select Properties.
3. Under the General tab, locate the Launch Options text box at the bottom.
4. Type or paste the following parameter:

   -force-d3d11

5. Close the Properties window and launch the game normally.

Optimal Graphics Settings for High Framerates

To achieve an ideal balance of visual fidelity and stable performance, configure your in-game video options as follows:

Preventing Base Lag & Conveyor Stutter

As your outpost expands to include dozens of auto-sorters, automated sweepers, and conveyor belts, CPU simulation overhead can bottleneck performance. Follow these optimization guidelines:

1. Avoid Multi-Tile Foundation Spanning: Never build large buildings across seams between unaligned foundation tiles; physics collisions can misfire and drag tick rates down.
2. Cap Unused Belt Loops: Never leave high-speed conveyor belts circulating loose dust capsules in endless loops. Always feed belts directly into a storage hopper or terminal depot.
3. Limit Overlapping Light Sources: Each spot lamp and vehicle headlight projects real-time shadows onto dust particles. Space out base floodlights every 15 meters rather than clustering them around your landing pod.

Multiplayer Host & Network Desync Fixes

When hosting up to 16 players in cooperative sessions, the host player’s PC handles physics simulation for all connected clients:

• Host on the Strongest Rig: Always designate the crew member with the highest CPU single-core clock speed and wired ethernet connection as the session host.
• Network Replication Rate: If clients report rubberbanding while driving rovers, open Settings -> Gameplay -> Network Rate and change the value from High (60 Hz) to Normal (30 Hz).
• Corrupted Save Prevention: Regularly back up your host save files by following our save file and backups guide.
