100% CPU usage / warning

Anyone getting this / the red pop up top left of the screen in red.

Don't seem to make any difference the #AI on track

Come to think of 1080ti are not exactly cheap at the moment and seem to be stuck at their price point for, at least to the near future

You should do what I'm planning to do:
- get a ryzen 3xxx on black Friday this year. As long as they prove to keep what they promise. I7 9700 single thread performance with more cores!

- wait for nvidia 3070 to arrive as the "true" successor of the 1070

I forgot to mention that I run the game at 2560x1080 on a Dell alienware AW3418HW with gsync

Since I wonder whether or not it's single thread limit warning or only full cpu load warning :
Could you unlock your fps and put the resolution scale to maximum eye cancer aka minimum so you'll definitely hit the cpu limit instead of gpu?
Would be great research!

Ya'll do what you've gotta do, but bear in mind that the current release has not been optimised for performance as Kunos were focused on stability with the re-write (according to Lord Kunos), so we should expect some improvements going forward.

I have made some prinstscreen (not a pro of such thing sorry.)

100-15 means scaling 100 / 15 AI
200-15 means scaling 200 / 15 AI

with 15 or 28 AI I have about the same fps with scaling 200, about 45 fps
cpu 23-26 %

with scaling 100 it is different
15 AI about 90-100 fps ; cpu 45 %
28 AI about 75-80 fps ; cpu 37%

Thanks for spending your time for this! You sadly did the opposite though and pushed into the gpu limit by increasing the reso scale.
I wanted you to hit the CPU limit by decreasing the reso scale to the minimum, taking away the load from the graphics card and the how your 8700k behaves.

 

[Kek700]

no FPS limit.

​

also limited FPS to 75 on next takes.


can up load some more

 

[manu68]

no problem. I will do the same with min resolution scale
(I should also look how to have all cpu on screen )

GPU bottlenecking.

it’s a bit confusing for me at the moment , my processor is not exactly that slow.
it’s 4 cores all running at 4.7 Ghz, not exactly shabby.
mine is 100% , others quote 30 - 40 odd %.. i know it’s not exactly a 9900k, but for an
piece of software ware that supposed to be core based !!!?.
There must , i assume be something wrong somewhere, but i have checked and checked
and can find no reason. No other programs running. the only anomaly may be that i do not
update my windows 10. so it’s remained static for some 12 months. But it’s been 100% reliable.

Checked all the images and I can see that your 6600k reaches almost 100% overall load while the 8700k reaches 45%.
So acc is able to make full use of 4 cores/threads.
It also makes sense since 4x100% means roughly about 30% of the 12 threads of a 8700k. Bare in mind that hyperthreading is mostly not able to push all threads to a 100% but also bare in mind that windows can make use of more cores/threads available by shuffling around.
That results in the maximum of 45% in Manu's Screenshots.

For acc its totally fine to reach 100% with a quad-core while it's indeed still strange that you say that it would happen in ac 1 too...

Also you don't know what others are saying is "true" like for example they limit the fps or their gpu hits 100% first due to being a different graphics card or just different graphic settings.
Then their CPUs won't hit full 100%...

I'm still interested in Manu's tests with minimum resolution scale (oh gosh does that look ugly btw ). Let's see how high the 8700k can go with his graphics setting but a gtx 1070 far away from its limit!

Happy to see that you already could achieve some conclusions. I will try to makes the test this evening. (After that I am suppose to change my internet box for a new one tomorrow. I may then encounter problems, because such thing is only easy on the paper ! )

Annoying stuff these Internet things... I wish you luck and success with it!

One thing just crossed my mind: have you set the amount of visible opponents to "all"? Just wondering why your fps are almost the same with 200% scaling at 15 and 28 AI.

I got an old rig built in 2015 but i have no problems runnung ACC on high settings. Foliage on medium ithink
I went for decent components at the time. It still runs anything ive tried in 2019 I not even overclocked (yet) and old DDR 3 mem.

Has anyone looked into API draw rate optimisation for Unreal Engine ?

 

[manu68]

I think so, but I will checked that this evening.

I had a look at how the turbo boost works.
A cpu frequency at 4295 mhz means that all 6 cores are used on all printscreens

[Hiikeri]

4 cores for UE4 -engine is too few, should be at least 8 thread CPU.

 

[Kek700]

Once I start pushing FPS, even in AC, which my
graphics card can easily achieve. My CPU is
starting to rail on all 4 cores too.
Nowhere near as repeatability as In ACC, in ACC
the CPU warning is going like crazy.
When static, task manager shows 1% cpu usage,
So there does not appear to be any pre loading
of cpu requirements prior to loading AC or ACC.
