Hi Mike, Thanks for the pointer about the GPU pipeline, I'll check it out.

I'm pretty anxious to try them out myself, but in this case, I don't think it would make that much difference. Sure, in percentage terms 6x more is a lot, but in absolute terms it's still not very much (20 cables with 20 segments of 6 quads each - 2400 quads... and even in terms of vertices it's not that many...), so I guess I'm doing something wrong. It's not the first time someone's displayed cables, and using geometry shaders was not an option until recently, so there's obviously something amiss.
