This is a beginner teaching beginners the fastest way to get up and mining ethereum with a windows laptop and a dedicated nvidia graphics card. I have a lenovo laptop with a core i7 10th gen computer with an RTX 2060 to give you a feel for the computing power I have.
Here is the code snipped to use (*****copy and paste YOUR ethereum wallet receive address over the "0xC7E104F8889c41e53c338C4c67357a869bfea35f" below...otherwise you'll be mining ethereum into my wallet...which I wouldn't hate, but I'm sure that's not what you're going for):
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
