Several of those 'top 3d engines' are doing stuff O ( n ^ 2 ) where it can be done O ( n log n ).


That's a bold claim. Can you give an example?

Yep. This thread degenerated and is way too off topic already. Feel free to contact the mods to delete it. I'd be fine with that.


Oh you could ask Johan de Koning, didn't he work a few years for ubisoft?

You realize they first have you sign 20 secrecy contracts before you can even deliver for $100 something? In some cases they just talk talk talk and still don't give YOU the contract job but throw it to the cheapest 3d world nation.

However if you analyze yourself the benchmark results of the big games you will see that MAJORITY of games doesn't scale with the number of cores times Ghz.

So that's the simplest form of proof you can find. And very conclusive evidence.

They are total dependant upon the bandwidth to the RAM of the GPU and the bandwidth of the RAM of the CPU.

You can easily verify this yourself.

Also if you open a book on graphics algorithms you'll figure out that it doesn't need to be like that. In the end it's not steering a trillion pixels. It's steering just a few displays with objects inside.

If you draw things in a simple manner, then you obviously need huge bandwidth. If you do it more clever, it'll work great at a GPU from 10 years ago.

Realize however that they focus upon supporting all features in a manner that it works for you. Optimization is simply not the focus, unlike game tree search.

The luxury the game industry has when producing games is that those gpu's deliver effectively several teraflops each.

However if you use a few displays of 2560 * 1600 or something like that you'll realize that it effectively can do with just a bunch of gflop.

So the rest is inefficiency.
