So im trying to do the render test, i have a older copmuter unfortunetly. Its a i3 2.20ghz 8.00 gb ram 64-bit os hp with windows 10, using the cpu (no dedicated graphics card) and im having trouble finding the best settings to render at. from 16x16 to 300x300 they all seem to take 2 hours to render the one image of the bmw. now i know i need a new pc, but can anyone give me a idea or something on how to speed up the rendering or anything at all please.
