Denshattack! PC Troubleshooting — Launch Week Fixes
Some PC players report crashes, black screens, or stutter during Denshattack! launch week on Steam — especially on certain GPU driver versions or systems with aggressive overlay software. Undercoders shipped a day-one patch addressing rare collision detection issues on consoles; PC hotfixes may follow via Steam news. Work through the list below before refunding.
Quick Fix Checklist
- Verify game files — Steam library → Denshattack! → Properties → Installed Files → Verify integrity.
- Update GPU drivers — NVIDIA GeForce Experience or AMD Adrenalin to latest stable branch (avoid beta unless desperate).
- Restart PC — Clears hung graphics contexts after first launch crash loop.
- Disable overlays — Turn off Discord, GeForce Experience, Steam overlay, MSI Afterburner OSD, and Xbox Game Bar temporarily.
- Run as administrator once — Right-click Denshattack.exe → Run as administrator to rule out permission blocks on first boot.
Steam Launch Options
Steam → Properties → Launch Options. Try one at a time:
-dx11— Forces DirectX 11 if DX12 path crashes on older GPUs.-windowed— Borderless windowed sometimes bypasses fullscreen exclusive crashes.-high— Raises process priority on CPU-bound stutter (use sparingly).
Remove launch options after testing if they do not help — leftover flags can cause new issues.
Visual C++ and DirectX
Install latest Microsoft Visual C++ Redistributable (x64) from Microsoft official downloads. Windows Update should deliver DirectX runtime components; run dxdiag to confirm no missing DLL errors when launching.
Antivirus and Firewall
Add Denshattack! install folder and Steam.exe to antivirus exclusions. First-launch anti-cheat or save-file initialization can trigger false positives on aggressive scanners.
In-Game Settings
- Lower shadow quality and anti-aliasing first — trick particles spike VRAM on 4 GB cards.
- Cap frame rate at 60 if experiencing coil whine or thermal throttle on laptops.
- Disable motion blur if dizziness masks actual frame drops.

Steam Deck and Handheld PC
Steam Deck Verified — if crashes persist, switch to Proton Experimental from compatibility menu and limit TDP to 12W for stability. See Steam Deck guide for control and battery tips.
When to Wait for a Patch
If none of the above helps, check Fireshine Games Steam community announcements and Undercoders social channels for hotfix notes. Document your GPU model, driver version, and crash symptom (menu vs in-track) when reporting — helps developers prioritize fixes. Refund window on Steam remains available if issues persist beyond troubleshooting.
