Diablo® III

Impressive Multi-Core Support

Impressed with the number of threads that Diablo 3 uses. Looks like it might even benefit from multiple processor setups with ~30 threads! Not that I can afford a 2 x Ivy Bridge workstation. Has anyone tried 8 core or more with Diablo 3?

That "threads" really isn't the kind of thread you are thinking of

How is it different? Aren't the number of threads = number of processes created by the program?

Yeah, but that does not necessarily translate into efficient, multiple cores in use. Programs that barely make use of multiple cores can still create a lot of processes.

See:

You can see that number of cores don't make all that much of a difference for Diablo 3 performance (at least for Intel processors).

Just did a test...D3 is really only using *1* of my cores to any great extent (around 60% usage). Getting a couple of small (20% or less) spikes here and there for an instant on one other core. So...I've pretty much got 6 unused. FX-8150.

That said, I can still max out the game with no issues. If I get un-lazy, I'll test out an area with a lot of physics and see what it does.

I dont think the tristram runs that Tom's Hardware did were a goood indicator of performance. Anywhere in Act IV or III would be more indicative. In fact they didnt really see much of a difference relative to processor speed. I wish they would have used a multi-gpu benchmark, because it looks like their test is GPU limited.
