Quick answer
Update the Prologue first, then test either /gldevice:Vulkan or /gldevice:D3D11 in Steam launch options. Patch 3 retained these workarounds for remaining boot crashes.
Verified July 18, 2026. This guide separates confirmed facts from unannounced features.
Add a launch option
- Right-click Neverway Prologue in Steam.
- Choose Properties, then General.
- Enter
/gldevice:Vulkanand launch. - If it fails, replace it with
/gldevice:D3D11.
Use one option at a time so the result is clear.
Check other blockers
If both paths fail, inspect Windows Security history for Smart App Control, verify Steam files, update the graphics driver, and confirm minimum requirements. Do not disable a security feature unless Windows records it as the blocker.
Report the failure
Include Windows version, GPU, driver, patch date, option tested, whether a black screen appears, and whether the process closes. This separates graphics initialization from security blocking and later loading problems.
Frequently asked questions
Should both options be combined?
