Out of Video Memory Error on RTX 5060 Ti 8 GB (Steam Build – Windows 11)

Technical Help

  • Game Version: Steam build 20646187

  • Platform: Steam Windows

  • Mods: Removed

  • Hardware Specifications & Operating System (OS version, CPU, GPU, RAM, storage…):

OS: Windows 11 Version 25H2 (Build 26200.7019)

CPU: Intel Core i5-14400F (10 cores / 16 threads)

GPU: NVIDIA GeForce RTX 5060 Ti 8 GB (Driver 581.80 – Game Ready)

RAM: 16 GB DDR5

Storage: 1 TB NVMe SSD

  • Steps to Reproduce:

  • Please provide the entire save file(s) from the date when the issue occurred.
    Save Files:
    None — the game crashes before creating any save data or config folders (only “User_data” is generated).

  • Details:
    I’m experiencing a consistent crash on startup with the error message:

    “Out of video memory trying to allocate a rendering source.”

    The game fails to launch after the optimizing game files screen — I then get a blackscreen where the intro video would usually play, (since I disabled intro with “skip intro settings”). After a while the error message pops up.

    I’ve confirmed that my system meets and exceeds the minimum requirements. This appears to be the same issue other RTX 40/50-series 8 GB GPU users are reporting, where Unreal Engine 5 over-allocates VRAM during startup.

    Steps I’ve taken so far:

    • Verified game files through Steam

    • Updated NVIDIA driver to 581.80 Game Ready

    • Updated Windows 11 to Version 25H2 (Build 26200.7019)

    • Cleared all local caches including:

      • %LOCALAPPDATA%\\NVIDIA\\DXCache

      • %LOCALAPPDATA%\\NVIDIA\\GLCache

      • %LOCALAPPDATA%\\D3DSCache

      • %LOCALAPPDATA%\\InZoi (User_data + Saved folders)

      • %LOCALAPPDATA%\\UnrealEngine\\Common\\DerivedDataCache

    • Performed cleanup in Safe Mode to bypass CrossDeviceResume file locks

    • Ran Disk Cleanup with DirectX Shader Cache selected

    • Created manual configuration files:

      • GameUserSettings.ini and Engine.ini with reduced VRAM pool (r.Streaming.PoolSize=1024) and windowed 720p mode

    • Used launch options:

      -forcereset

    • Disabled Hardware-Accelerated GPU Scheduling

    • Restarted system and reinstalled the game

    Despite these steps, the same “Out of video memory” crash occurs every time. The crash happens instantly, before any loading or graphics initialization.

    No save data or gameplay settings are ever created — only a small “User_data” folder appears under %LOCALAPPDATA%\\InZoi.

    I suspect this may be related to Unreal Engine 5’s memory pool management or a missing fallback for GPUs with 8 GB VRAM.

Thankful for any help!
