I have a dedicated graphics card in my pc (Nvidia GT 610), running windows 10 pro. But it's not detected in Cycles render settings. Pls lemme know how can i render in GPU. Kindly refer to the attached screenshots.
Your graphics card has a CUDA compute capability of 2.1, however GPU rendering in Blender 2.8 requires a compute capability of 3.0. That is why your graphics card isn't listed.
