if you can see the memory is 15/16 and only d5 is working (not rendering)

Hi @connect2

Indeed, you do have a strong device running RTX 5070 Ti, but VRAM also plays a huge role in working with heavy files. May I know how big the file size is on this current project that you’re opening? Please send us a screenshot of the file size.
