The streaming helped it a lot but I think the cost of larger carts was a big drag on what developers could do. It is one thing to stream textures but if you cannot afford the cart size in the first place it becomes merely academic.

- pezezin 3y agoThe real problem was different. The PS1 cache was a real cache, managed transparently by the hardware. Textures could take the full 1 MB of VRAM (minus the framebuffer, of course). In contrast, the N64 had a 4 kB texture RAM. That's it, all your textures for the current mesh had to fit in just 4 kB. If you wanted bigger textures, you had to come up with all sort of programming tricks.
