3d is extremely slow

Hi, whenever I use the 3d it's incredibly slow.  Takes like 10 minutes to render in low quality raytrace. Or if I try moving the lights around, or shadow in preview mode. I have: amd ryzen 9, 64gb ddr5, Nvidia 4090. Why is it so slow? I am a 3d modeler and use cinema 4d. I can render extremely fast. An entire scene with over 10k polys, raytracimg, caustics, subsurface you name it. I can even model in real render time. Yet, illustrator I make a sphere and it just lags. Please help
