How many cpu cores

[godliikekyle]

i know the game requires an i-5 for the minimum which has 4 cores. but what i want to know is how many cores are actually being used in game, does anyone know?

[Dukie]

All 4 of them or however many you have. For me it is accessing all 4 of my cores.

[godliikekyle]

so your saying at the minimum it uses 4 but if i had an i-7 it would use the 4 physical cores and at least 1 on the virtual cores?

I'm not 100% sure but I'm pretty sure if your CPU supports hyperthreading it will use all of the physical- and virtual cores. Makes sense to me.

I ment Hyperthreading sorry. Corrected.

Damn, thanks so answering my question

Why do you ask? You got a dual core?

[godliikekyle]

no, i have an i-5. im actually in a college course for IT tech. and my teacher asked if it actually used 4 cores or not. since i dont own the game i can't test it out myself

Gotcha. I guess you got your answer.

Again I can only confirm it does on 4 physical cores according to MSI Afterburner. My CPU doesn't support hyperthreading so I'm not sure about that.

As far as I can tell, the game only uses 2 cores. Process Explorer only shows two cores in use, and I can force the CPU to use only two cores with no adverse affect on performance. Bumping it down to one core does nuke the framerate.

Now, if it actually CAN use more than 2 cores it doesn't really use them very well. On my i5-2500K CPU use of the witcher3 process almost never goes above 50% of total utilization, indicating only 2 cores really in use.

Don't own the game! What's wrong with you? You've got an i5 & here's me struggling to fully appreciate it's beauty with a paltry i3. Rush out & get a copy post haste you fool! :)

Yeah well I beg to differ. The Witcher 3 is very light on the CPU anyways and almost entirely depends on the calculation power of the GPU. So assigning only two cores to the Witcher 3 doesn't hit performance too much doesn't surprise me at all.

I just now did a little test run just to make sure and all 4 of my cores are qually taxed around 50-60%. So I think it is strange that we get such different results kamikaze.kyle.

I am kinda curious. The game only uses a handful of threads when I debug it, and by and large there are only two threads which really use any noticalbe CPU. Outside of those two main threads, the total sum of all the other threads hovers around 5% CPU use at most on my processor, which, if it really does use more than 2 cores, doesn't use them effectively (or need to, either/or).

Oh, and you can't view the overall CPU use to see if it's multi-core or not. You have to view the individual process. Windows will move threads from other processes to other cores to do load balancing.

EDIT: Hrm, prolly does use more than 2 cores, just not every effectively. /shrug again.

Yeah I know, but the total of the background processes don't use 50% of even one of my core when added up, so that doesn't make sense to me.

I don't know what to say mate. :)

Game is very good at using all cores equally. If you are asking if a dual core CPU can run the game, yes. People have reported to play the game with a dual core.
