So on fewer cores it runs badly? Like everyone has said? Thanks for that!
What is the point of trying to run the game on 1 or 2 cores, most modern games are requiring quad core as minimum because that's what you need to run all the complicated interconnected systems of modern software. Who wants to run Forza: Flipbook? If you can get it running well under minimum specs i'm sure some people will thank you for that, but I don't think you will. Minimum specs are there to give people an idea of the hardware they'll need to run the software. But we all know min spec is hardly ever an enjoyable experience, so trying to run with hardware below that just seems like self flagellation.
Have you tried downloading some more RAM off the internet...?

the point is that if the game could utilize all cores available and not half of them,
A pentium g3258 oced using both core could run this game AT LEAST on medium graphics with a little bit better optimization.
forza 6 apex BETA is maybe the worst optimized game so far, thats a fact!
Lets hope it will be fixed at launch

I dont see any reason for it requiring any more than one full core at the moment.

On my rig, FX-9590, it uses two threads and the other 6 have a small workload (25%), probably distributed throughout the remaining cores, but the CPU is not limiting the game.
It runs at 60fps, even with 2560x1440p VSR on High with one R9 280X.

Your asking for the game to use resources it doesnt need, or your CPU is WELL BELOW THE REQUIRED.

What do you expect for a 65 Euro CPU? Next you'll be saying that this should run on and Intel HD 3000 GPU.

On my new skylake build the CPU runs two cores at 90-100% the other two cores go between 25 and 60% depending on the race/weather etc. I've already said that, so making it run on one core isn't going to make any meaningful impact on performance. As for it only using half cores, that is some of the time, and probably at low settings. With everything on ultra it starts to utilise those other cores as well.

Minimum CPU requirements are the equivalent of 6 athlon 5130 cores since that's what the consoles have...

g1820 gtx 650 @1080 high ~25fps while recording@yas marina,closing every prog and going full screen it plays at about 28fps, 30fps is the minimum since that's what you can select in the game settings.

That's not how it works. Console requirements are ALWAYS lower as they have a set target to aim for that they can optimise to. With PC they have so many different CPU's to take into account they can't optimise as well, so they have higher minimum requirements to make sure things run. It has always been this way.
As for the freezes and stutters i'm not getting them, and neither are lots of others so not everybody is getting them. It's another case of those who are getting them assume everybody is. Which is almost never the case. Many different issues can cause the stutters and as not everyone has identical hardware the world over unlike consoles it means narrowing it down. But if people come along and say everybody is getting it that's not helping.

and what does the cpu have todo with optimization (in this context)
if you have a slow section of code or a thread going nuts or a memory leak that has zero bearing on what cpu you are executing on thats a pure programmatic error
secondly for the 8th time the consoles are not 8 core they are 8 thread and there is a huge hugeeeee difference in both how you approach programming on them and what kind of performance you are going to get vs say even a modern intel dual core just because you don't have 4 or 8 threads doesn't mean you can't get the same performance (especially when you are comparing AMD to intel)
and as it stands now this game could run perfectly fine on a g3258 with a full field of AI and still have power to record video ....

this is evident by looking at the threads via process hacker and iding how they are allocating stuff and right now they have a lot of overhead and threads sitting and spinning doing nothing

Does it?Or does it just show thread migration?
Do you get 100% load on all 4 cores or did 2x100% turn into 4x50% ?
Same exact threads being tossed around between the cores without any benefit.
If you could check with process explorer, or similar program,if you got 4 threads with close to equal % running all at once,that would be great.

Update didn't change anything for me.

Only fix right now is to manually manage the running threads...
What I changed can be seen at 10:19
basically
Thread with highest usage, affinity to only core 1 at priority of idle
--- second -- 1 --- above normal
highest usage threadpool only core 1 ,priority unchanged
As many of the other threads as you can only on core 0.

I have to lower some threads just to get it to start so your mileage on what you have to change may vary.

While in the game, if I alt+tab out and open the process in task manager and "set affinity", disable CPU 0 then play forze, alt-tab out once again and re-enable it, the stuttering and freezes stop.

I'm running Apex on i7-5500U(dual core) and AMD R5M330 (both OC'd at 3GHz and 1100MHz resp. ) & 8GB ram.(I know it's the bare minimum)

But for some reason every time I start the game, 2 of the 4 logical cores (specifically CPU2 and CPU3)get parked. I'm using ParkControl and that has enabled me to run the game at 3Ghz on only 2 cores and the game runs fantastic for most of the part except for the occasional disappearance of everything except my car, which I got to know is the non-execution of other threads. Can please anyone tell me how may I unpark those cores while playing (apparently even ParkControl and advanced settings can't do this.),so I get to enjoy it completely?

Hi,
here you can see a picture of my CPU when I play Forza 6 Apex.
I see 2 CPUs with 100% and the others do much less or somtimes nothing. Any ideas why? Is it normal?

Wow. I am blown away. So I tried out all of the affinity and thread changing stuff first and then did a few races. It only made things worse, with even more frequent stuttering and lower frame rates. Set things back to normal and got back to 60FPS lock with a stutter or hitch every 4-5 seconds. Decided to go through task manager and change the priority of the game executable to "below normal" and do a few more races. Game ran the same. Rio in daylight was playable but full of stutters, Spa in the rain was an unplayable stutter fest and so on. Decided to change the priority of the game to the lowest setting possible (low I think it was) via the task manager details menu..................HOLY COW! The game runs like a dream now! Played a 6 lap race on Rio full with 16 cars and not a single stutter! Proceeded to play Brands, Spa and Yas with the same result. This is with maxed settings and 4k resolution. The only time I can get it to drop under 60FPS is on Spa in the rain and 8xMSAA, so I just turn it down to 4xMSAA and it is perfectly playable and looks the same in motion. Yes, the game still does the stupid maxing out of only 2 cores, but it runs flawlessly in my case like this.

The last few laps of my Brands race in GT3 cars I actually forgot that I was playing on PC, something that hasn't happened since the release of FM6:Apex. Having a full race locked at 60FPS with zero stutters, just like the X1 can do, totally got me in the zone and put a big smile on my face even though I finished 6th! No matter the level of skepticism, I would at least give this ~10 second fix a try and see if it helps you out at all. CREDIT TO BallaZ83.

TL:DR - Open game, open task manager, go to details tab, right click on forzamotorsportapex.exe, change priority to low, go back to game.

If anybody relevant from T10 sees this, my system is as follows.
ASUS Z97-A 2801 BIOS
i7 4770k @4.4GHz w/Hyperthreading enabled
EVGA 980Ti 6GB @1400/7800

It worked, thx a lot for the tip!!!
Open game, open task manager, go to details tab, right click on forzamotorsportapex.exe, change priority to low, go back to game.

My specs: I3 4170 @ 3.7 ghz and a Gtx 960 2gb vram and after setting it to low priority it uses all the threads at about
Cpu 1: 91%
Cpu 2: 60%
Cpu 3: 95%
Cpu 4: 80%

and the game runs ok in 60 - 80 fps all settings on high, no stutter on any track rain night full grid or watever. Hope we see some optimization in Horizon 3 and we don't have the same problem

And for the rest of us who have quad cores or better the real problem here is the disk activity/swapping causing the game to chug and in those cases faster disk access would help alot.
It has absolutely nothing to do with cpu bottlenecking if the game runs fine and then starts stuttering after a few races and that suggests there is serious issues with memory management or some serious memory leak somewhere.
On my system for example I saw a HUGE improvement from just using my actual physical ram as a ram disk to prevent windows from using my physical disk for virtual memory.
The game isn't bugged. I've seen reviews of other DX12 games and all of them do this. They only use half of the available cores instead of all of them
