It says "unknown"
Edit: after reinstalling the GeForce driver, it now shows 10_0. But the game still fails to start with "DX11 feature level 10.0 is required".
Viewing post in Game demands DirectX11 FL 10.0 but GPU supports 10.1
The laptop in question has a dedicated graphics card, not an integrated graphics card. The laptop with the integrated graphics card is a different laptop entirely. The game runs on that laptop, on Linux, but the performance is unplayably awful (The old school graphics should in principle be totally manageable, but I suppose the game isn't optimized with older hardware in mind). That is why I am trying to run it on my other laptop, on Windows, with a dedicated GPU. That is where the error occurs. I've already reinstalled Nvidia drivers and DirectX runtimes several times. I am 100% sure I've installed the right ones. It simply doesn't help. There is no obvious reason for this to be happening. My GPU supports exactly the feature level required. dxdiag says so.
