[1.1.37] Error on startup - D3D11_ERROR: DXGI_ERROR_UNSUPPORTED

[Muche]

Hello.

Has minimum GPU requirement increased in version 1.1 to DirectX 11?
I have quite old GPU (ATI Radeon HD 3650) and it worked fine in version 1.0, but now in version 1.1 it errors out during startup:

Code: Select all

D3D11_ERROR: D3D11CreateDeviceAndSwapChain failed in createDeviceAndSwapchain on line 743. Error [0x887a0004] - DXGI_ERROR_UNSUPPORTED
Error Util.cpp:83: Failed to initialize DirectX. Factorio requires DirectX 11 compatible graphics card or better.

I have tried various launch options; I was able to get it to run using Microsoft Basic Render Driver, but the performance was poor.

Thanks.

You're running the demo right? I believe the demo is set to require DX11, but the full game (may) work on your GPU which supports DX 10.1.

We recommend a DX11 GPU since the game will likely run poorly on that GPU but you can always try it.
