⚠️ Why Is RoadCraft Lagging or Running Slow?

Before we jump into solutions, it helps to understand what may be causing the performance issues. Common causes include:

Cause	Description
🎮 Outdated GPU Drivers	Missing performance patches or compatibility updates
🖥️ CPU Bottlenecks	Heavy simulation mechanics stressing older CPUs
💾 RAM Usage Spikes	Memory leaks or inefficient resource handling
📦 Corrupted Game Files	Broken assets or scripts slowing rendering
🔌 Background Overlays	Discord, Steam, OBS interfering with performance
🧩 Mods & Custom Content	Unoptimized or outdated mods causing lag
🎨 Graphics Settings Too High	Ultra settings not optimized for your hardware
🧊 Storage Issues	Slow HDDs or fragmented SSDs affecting load times

Now let’s look at how to fix each of these issues.

💡 Step-by-Step Fixes to Improve RoadCraft Performance

Here are 10+ expert-tested methods to boost FPS, reduce lag, and eliminate stuttering in RoadCraft.

---

🔧 Fix 1: Update Your Graphics Drivers

Outdated or incompatible drivers are one of the biggest reasons for poor performance in PC games.

Steps:

1. Press Win + X → Device Manager
2. Expand Display adapters
3. Right-click your GPU → Update driver
4. Choose Search automatically for updated driver software

Alternatively, download the latest driver directly from your GPU manufacturer:

• NVIDIA: https://www.nvidia.com/Download/index.aspx
• AMD: https://www.amd.com/en/support
• Intel: https://www.intel.com/content/www/us/en/download-center/home.html

📌 Use DDU (Display Driver Uninstaller) in Safe Mode for a clean install.

---

🧰 Fix 2: Optimize In-Game Graphics Settings

Sometimes ultra settings aren’t optimized for your specific hardware.

Recommended Settings for Smooth Performance:

Setting	Recommendation
Resolution	Native resolution (or lower if needed)
Texture Quality	Medium–High
Shadows	Low–Medium
Anti-Aliasing	TAA or FXAA (avoid MSAA unless GPU-heavy)
VSync	Off or Adaptive
View Distance	Medium
Ambient Occlusion	SSAO (SMA only if powerful GPU)
Reflections	Medium
Post-Processing	Low
Foliage Detail	Medium

📌 Avoid using Ultra unless you have a high-end GPU (RTX 3070+ or equivalent).

📈 Fix 3: Enable Performance Mode in Windows

Windows has several power-saving modes that can throttle performance.

Steps:

1. Press Win + I → Go to System → Power
2. Select High Performance or Balanced mode
3. Click Additional power settings
4. Edit plan settings → Change advanced power settings
5. Under Processor power management, set:

• Minimum processor state: 100%
• Maximum processor state: 100%

📌 This ensures your CPU runs at full speed while gaming.

---

🛑 Fix 4: Disable Overlays & Background Applications

Third-party overlays like Steam Overlay, Discord, OBS, and Razer Synapse can cause performance drops.

Steps:

1. Press Ctrl + Shift + Esc → Open Task Manager
2. Under Startup tab, disable unnecessary programs
3. Temporarily disable:

• Steam Overlay (in Steam → Settings → In-Game)
• Discord Overlay (in Discord → Settings → Advanced)
• OBS, MSI Afterburner, etc.

1. Restart your PC and launch RoadCraft again

Also try disabling Resizable BAR, DLSS Frame Generation, or RTX Remix features if enabled.

---

📦 Fix 5: Verify Game Files Integrity (Steam / Epic)

Corrupted or missing game files can lead to performance issues and crashes.

For Steam Users:

1. Open Steam
2. Right-click RoadCraft → Properties
3. Go to Local Files tab → Verify integrity of game files

For Epic Games Store Users:

1. Open Epic Games Launcher
2. Go to Library
3. Click the three dots next to RoadCraft → Verify

This will scan and repair any damaged or missing files.

---

🧬 Fix 6: Adjust Affinity & Priority in Task Manager

If your CPU is bottlenecking the game, assigning more cores or increasing process priority can help.

Steps:

1. Launch RoadCraft
2. Press Ctrl + Shift + Esc → Open Task Manager
3. Find roadcraft.exe under Processes
4. Right-click → Set affinity
5. Assign all available CPU cores
6. Right-click again → Go to Details
7. Right-click the process → Set priority → High

⚠️ Only do this if you know your system is stable — setting too many apps to high priority can cause instability.

---

🧪 Fix 7: Run the Game as Administrator

Sometimes permission issues prevent the game from accessing critical resources.

Steps:

1. Right-click the game shortcut or executable
2. Select Run as administrator

To make this permanent:

1. Right-click the shortcut → Properties
2. Go to Shortcut tab → Advanced
3. Check Run as administrator → Apply

---

📁 Fix 8: Clear Shader Cache & Temp Files

Shader compilation errors or bloated caches can cause stuttering and FPS drops.

Steps:

1. Press Win + R → Type %temp% → Enter
2. Delete all temporary files
3. Also clear shader cache located in:

   C:\Users\<YourName>\AppData\Local\RoadCraft\Saved\ShaderCache

📌 Avoid deleting files while the game is running.

---

🧱 Fix 9: Disable Antivirus/Firewall Temporarily

Some security software blocks background processes and file access, which can slow down game loading and performance.

Steps:

1. Temporarily disable:

• Windows Defender
• Third-party antivirus (e.g., Avast, Bitdefender, Norton)

1. Add RoadCraft as an exception in your firewall
2. Try launching the game again

📌 Always re-enable your antivirus after testing.

---

🎛️ Fix 10: Lower Background Simulation Load

RoadCraft includes heavy AI and simulation elements (like scavengers, wildlife, and environmental decay), which can impact performance.

Tips:

• Reduce number of active NPCs via settings (if available)
• Avoid densely populated areas if performance drops
• Play on smaller maps or sandbox modes if possible

---

🧠 Bonus Fix: Analyze Performance Logs (Advanced)

If none of the above work, you can analyze crash and performance logs to find bottlenecks.

Steps:

1. Navigate to:

   C:\Users\<YourName>\AppData\Local\RoadCraft\Saved\Logs

2. Open the most recent .log file
3. Look for lines containing:

• Slow task
• Stutter warning
• Memory usage
• GPU utilization

🔍 Tools like MSI Afterburner, HWMonitor, and Task Manager can also help monitor real-time performance metrics.

Report findings to the RoadCraft support team or forums for deeper analysis.
