When in need of large number of indices, is it recommended to use many 16 bit buffers or just one 32 bit buffer? I realize some cards cannot handle 32 bit buffers, but i'm talking about the ones that can.

If you use 16 bit buffers for large objects you might although need to split the vertex buffers. If you don’t mind the additional memory using 32 bit indices would simplify the job. Additional you might be able to reduce the number of needed drawcalls.

But you should be careful. Even if a card supports 32 bit indices the number of primitives per draw call may still be limited.
