So, the relevant minimum requirements for windows are: Graphics card with DX10 (shader model 4.0) capabilities and CPU: SSE2 instruction set support. It might be the DirectX, try to download DX 11(latest), If your laptop does not support directX 10 there is nothing I can do about it, that is a requirement of the game engine. OpenGl is the 3D rendere for Linux and Mac, not for windows; DirectX is for windows. I saw a option to use OpenGl for windows but I don't have the time to investigate/compile such a custom build. I should have enough time after I release this version(0.7.0) but please write to me again after I finish this version to remind me to compile it with that special modification.
