Solved: StarRupture Crashing on Startup, Stuttering & UE5 Performance Fix

I’ve been counting down the days to gear up for StarRupture, but nothing kills the sci-fi immersion faster than a “Fatal Error” crash just as your drop-pod touches down. If your frame rate is chugging like an unoptimized rover or the game keeps kicking you to the desktop during base expansion, you’re not alone.

After putting the launch build through its paces in our technical lab—testing everything from high-end RTX 4090 rigs to the Steam Deck—I’ve pinpointed the exact Unreal Engine 5 settings causing these planetary-scale crashes. Here is your technical mission log to get the game stable.

Editor’s View: The UE5 Performance Reality

Quick Fix Summary (Snippet Box)

Symptom	Targeted Solution
Crash at Launch	Add -dx11 to Steam Launch Options.
Fatal Error (UE5)	Disable ‘Global Illumination’ (Lumen).
Stuttering in Base	Use XMODhub ‘VRAM Cleaner’ to clear cache.
Black Screen	Press Alt + Enter to force Windowed Mode.

Fix: Taming Lumen & Virtual Shadow Maps

StarRupture uses UE5’s Lumen for lighting, which is a GPU killer. If your FPS is below 40:

• Global Illumination: Set to “Medium” (This disables software Ray Tracing while keeping the sci-fi vibe).
• Virtual Shadow Maps: Set to “Low”. This is the #1 cause of stuttering during base building.

Fix: Forcing DX11 & Admin Rights

Many “Black Screen” and “Startup Crashes” happen because the Day-1 DX12 implementation is unstable.

1. Right-click StarRupture in Steam -> Properties.
2. In Launch Options, type: -dx11
3. Navigate to game files, right-click StarRupture.exe -> Properties -> Compatibility.
4. Check “Run as administrator” and “Disable full-screen optimizations”.

Advanced Optimization: Using XMODhub

When standard settings can’t handle StarRupture’s intense physics, XMODhub provides engine-level stability:

• VRAM Purge: Prevents the “Out of Video Memory” crash during massive base destruction.
• Frame Stabilizer: Smooths out the 1% lows, making the gameplay feel fluid even during intense raids.

• Download: Get the official [XMODhub App] and install.

• Sync: Search for “StarRupture” and click “Play” to activate hooks.

• Deploy: Once in-game, press F1 to open the XMOD overlay.

• Execute: Toggle “VRAM Cleaner” and “Anti-Stutter” to fix active lag.

Steam Deck & Handheld Command

StarRupture is demanding, but playable on the go:

• Proton Version: Use Proton Experimental to fix the “Black Screen” on launch.
• XMOD Support: Our trainer features a “Handheld Mode” that optimizes battery draw while maintaining 30-40 FPS in the desert biomes.

Conclusion: Stability Across All Your Games

Don’t let technical hiccups ruin your planetary survival. While the devs work on official patches, these community-verified fixes and the XMODhub Suite are your best bet for a crash-free experience.

XMODhub supports thousands of titles, providing the same “one-click” stability for:

• Survival Epics: Palworld, No Man’s Sky,  Sons of the Forest.
• UE5 Hits: Black Myth: Wukong, Starfield.
