Arma Reforger Performance Optimisation Guide

Why optimisation matters ⚙️

Arma Reforger looks and feels incredible, thanks to Bohemia’s Enfusion engine but it’s also demanding. Between its large-scale maps, physics simulation, and complex AI, performance can dip fast if left untuned.

Whether you’re commanding a private unit or hosting an open session, these tweaks will help keep your FPS stable and your experience silky-smooth.

Step 1: Update everything first 💻

Before changing settings, start with the basics:

• Update GPU drivers (NVIDIA, AMD, or Intel).
• Verify your game files via Steam or Xbox.
• Close background apps like browsers, Discord overlays, and streaming tools.
• Keep Windows Game Mode and Hardware-accelerated GPU scheduling enabled.

💡 Tip: Restart your PC before long play sessions, Reforger’s engine performs best with fresh memory allocation.

Step 2: Tune in-game graphics 🎮

The default settings lean towards high visuals, not smooth play. Adjusting a few options can give huge FPS boosts.

🧠 Pro tip: Test performance using the Everon map, it’s the most demanding terrain and a great benchmark for tuning.

Step 3: Adjust launcher parameters ⚙️

Add these Steam launch options to help optimise memory and CPU handling:

-high -USEALLAVAILABLECORES -maxMem=16384

These commands prioritise the game process and allocate more memory if you’ve got 16GB+ RAM.

💡 Tip: Test each parameter one at a time, systems vary, and not every tweak works for all CPUs.

Step 4: Reduce AI and simulation load 🤖

AI units are one of the biggest performance drains. If you’re hosting or editing missions:

• Limit AI count to 60–80 total active units.
• Disable unnecessary patrols or idle groups.
• Use AI caching scripts to freeze distant units.
• Avoid overloading with physics-enabled props.

🎯 Pro tip: For co-op missions, use headless clients or offload AI to separate instances for major CPU gains.

Step 5: Optimise network settings 🌐

If you’re running a server, ensure stability by editing your server.json or config files:

"maxPlayers": 32,
"bandwidthLimit": 25000,
"tickRate": 30,

• TickRate 30–40: A sweet spot between performance and sync.
• Bandwidth Limit: Adjust based on your connection upload speed.

💬 Tip: Schedule restarts every 8–12 hours to clear memory leaks and keep desync low.

Step 6: Use performance-friendly mods 🧩

Some mods enhance realism but hurt FPS. Choose wisely:
✅ Keep: ACE-like gameplay mods, UI tweaks, lightweight sound packs.
❌ Avoid: Heavy AI or weather scripts on public servers.

🧠 Pro tip: Use Workbench’s performance profiler to see which mods or scripts are consuming the most resources.

Step 7: Check temperatures and usage 🌡️

If you’re seeing frame dips:

• Use MSI Afterburner or HWInfo to monitor CPU/GPU temps.
• Keep temps below 80°C for consistent performance.
• Cap your frame rate to 90–120 FPS to reduce heat and stutter.

🔥 Bonus tip: Laptops should always run on max performance mode, Reforger pushes both CPU and GPU heavily.

Step 8: Server-side optimisation for admins 🧰

Running a dedicated or rented server?

• Use SSD or NVMe drives for faster mission loads.
• Limit map rotation and clean logs weekly.
• Disable unnecessary scripts or mission intros.
• Keep server tickrate steady (30–40 is ideal).

💡 Tip: Hosting with ChipHead ensures consistent uptime, dedicated CPU threads, and low-latency connections, perfect for mod-heavy Reforger sessions.

Step 9: Regular maintenance 🔄

Small habits make a big difference over time:

• Restart before every new session.
• Update mods weekly.
• Rebuild your config files after large patches.
• Delete temporary cache folders occasionally for smoother load times.

🧠 Pro tip: Save backup copies of your optimised configs, it’s easy to restore them after updates.

Final thoughts 💭

Arma Reforger is a technical marvel but it rewards players and admins who take the time to tune it properly. With a few smart tweaks, you can maintain buttery-smooth performance even in massive firefights.

If you’re hosting through ChipHead, your setup already has the high-speed storage and CPU stability needed for Reforger’s demanding engine. Focus on the mission, we’ll handle the frames. 🎯
