For photographs, 180 dpi is often sufficient for large prints. For diagrams, which are less complex, you might even get by with less, maybe even 120 dpi. You could try rendering a portion of your image at that resolution (e.g. 540 x 540 for a 3" square) and see how it holds up at a normal viewing distance.
