How much cores is Pillars able to use?!

Question

Hi there,

 

how much cores can be used by Pillars of Eternity?

I've got a Xeon CPU with Hyper-Threading - 4 Cores / 8 Threads.....

When i look at MSI Afterburner during gaming the CPU load is on

Core #1 #3 #5 #8.

On Core #2 #4 #6 #7 is 0% load.

My real cores are #1 #3 #5 #7.

So why is Pillars using only 3 of my 4 real cores and uses a simulated one instead? #8

Is there something wrong how cores get handled?!?

Because i got performance issues in some crowded areas down to 45 fps allthough I got

1 core left idling.

Bad optimization ?!?

You've misunderstood how hyperthreading works. It's not like there are 4 real cores and 4 simulated cores. There are 4 cores, and each core can run 2 threads. It doesn't matter if one or the other thread is using the core.

 

Looks like Pillars of Eternity can't really utilize the upside of hyperthreading, which is letting two threads both perform work simultaneously, as well as letting the cores switch between threads when one thread is waiting for data. But being able to effectively spread the workload to 4 cores is already pretty good.

Ah damn. Oke guess it's my fault then.

Thought the second thread of a core gets utilised

when the first thread is under full workload....

In Dragon Age Inquisition for example all 8 threads got

big workload on em. Frostbite seems to be a really good engine....
