Anybody with a 6-core CPU (especially Intel)?

I certainly believe you when you say it is better with HT, but I'm afraid my knowledge of the english language is not enough to appreciate the difference between the adjective you used. Talking about sensation/feelings is hard enough when speaking in my mother language...
But maybe you can also try the "experiment" I suggest and report, if you want.

Even thought, at this point, it should be more interesting in hearing someone with an Amd cpu now (Alex72 has one...)

And sorry: this way I'm also hijacking this "Intel based" Thread.

 

Hehehe... don't worry.

It's all good info for everyone.

Fluent = biegły... would that be right.??

 

Ehmmm, no!
Google translator suggest me that biegly is Polish... and I'm not

Anyway, I know what fluent mean... I was only saying that it is not easy to understand other people's personal "sensation"

 

I don't think it's actually utilizing all 6 cores, but hard to tell...

 

Ahhh... i got you.

sorry about biegly it was worth a try, of'cos i'm not either.

 

Got a 3930K running 4.8 ghz, and in races with AI it does prove its worth, hardly any FPS drop at all. from 120 ish to 105-110. Neglectable at least
Thats on triple screens.

 

Not an absolute, but it is using them.

Take a look at overall CPU usage, it's ~30 - 40% over the 6 cores.
Then look at core #2 it's using 10 ~35%.

It is hard to tell though cause the sim isn't fully in focus, but it's a really good sign.

 

Yeah it's really hard to explain mafrien'.

I just felt it was(not smoother), more kinda fluent.
Just a better experience overall.

 

It seems all 6 core are working... do you mean that it is possible that a couple of it could work for something different then the game?

Anyway, if with Intel the resource monitor shows only 4 threads occupation, it means that with AMD 6-8 core there is a difference...
Does the resource monitor show the INTEL like 8 different core?

 

Its fluent, thats true. Overall AC has been running very well ever since we got a go with it. GPU usage is boss, 95% to 99%. CPU usage is good aswell.
Nice job Kunos, honestly so many devs that fail to utilise resources.
But you guys have defintaly not forgot about it.

 

+1...

Same for me also.
Even back when the TP was released nearly a year ago(woah how time fly's), the sim has never let me down.

Keep it up Kunos.

 

I checked in the web and, yes, the resource monitor shows Intel cpu like 8 different cores.
Could you please make for me the same test? Just to confirm what bigbawmcgraw already told us.
I'm really very curios now. If so, AC could be one of the very few game that take advantage of amd multicore technology.
Please......

 

Maybe I found out the reason why you tried with "biegly".
And no...I'm not on facebook!

 

Since i didn't know where you were from,(nationality) looking at you profile here on AC forum, i thought... g00gle.
It was only to see where Jacopo originates from(country).

Pol was the first one that came up soooo.
so see where thought got me. rofl

Me no like faceb00k either, for good reason. ^^ ^^

 

I don't know a huge amount about how modern CPUs work, but a single thread can switch cores over time (and usually does unless you limit the app to one cpu)... what it can't do is run faster than 100% of one CPU's time at once. So if it's 50% of the time on one core and 50% of the time on another, that's the fastest the thread can be executed, but both CPUs will show up as ~50% usage.

Actually Process Explorer does a better job of showing what's going on. (although again, these are out of a max of 16.6% per CPU)

nvwgf2um.dll is gonna be the DX10/11 drivers for my nvidia card; acs.exe is doing physics & such. WINMM.dll is apparently sound.


This is what it looks like when I'm the only one on track - the graphics thread's still working hard, but acs.exe and WINMM.dll have dropped off a ton. (both these are in the Abarth 500, first is the special event, second is practice mode)

Maybe it's the sound of 12 cars that's the slowdown??

 

Rather odd things are happening for me now.
Just tried 26 cars at Monza (I know that's not official yet) and the CPU was trying to run all cores, albeit unsuccessfully.
Similar to what others are saying now.

 

That looks fine to me bbm, as if it's distibuting the load between all cores pretty well.
Seriously... that looks good.
Although i do see dips and straights, again i think it's maybe down to losing true focus on AC.

OT... hope you don't mind me giving you that acronym, although technically it's, it's just been shortened.
I knew it, i woulda' been quicker just typing bigbawmcgraw.

 

lol it's usually shortened to bbmg but bbm is fine too

The reason I thought it was odd was because before it was only using 4 of the 8 threads, although I can't remember if that was a KS approved special event which I think only has 12 or 14 cars, where as the one above is with 26 cars on track. With this car/track configuration I am getting pretty serious frame drops, especially at the start with lots of tyre smoke but I live in hope it will be optimised.

 

6 core/12 thread can execute @100%
1cpu=2 threads... by your understanding, if 1 cpu=2 threads are maxxing out it can only reach 100% between the 2 threads - hence 50% each.

That's possibly misunderstood mafrien'.
What i said above... 6core cpu can execute and load 100% - simple terms 6cpu's=600%
Same CPU but HT enabled... 12 threads can execute and load 100% - simple terms 12=1200%

simple terms again... this doesn't mean double the code is written, it just means that you're trying tofill every availabe gap(chunks of code) on the CPU

Go and try prime and set it to use all threads(12) and every thread will load @100%.
Oh be careful though, it's not recommended.!!

 

Hey don't worry about the smoke on the grid. They're gonna' give us a slider to adjust that.

But even with minimal smoke settings, i would imagine you're still gonna' be able to see the AI lock up at certain corners.
I mean really... who needs to see AI sitting doing burnouts @ the start of the race.??

I don't care how many frames i drop, that smoke's getting set to minimum.
