Drop Frame & CPU & GPU Resource

 

Hi i'm Ken.

I am using UE5 for aximmetry and cooked UE5 start map (there is only 2 Chair & table).

Aximmetry has more than 200% CPU&GPU. However, Task Manager on your PC has a very low usage rate.

The raytracing and reflection is off at the unreal level. and Preference - Rendering Setting is FHD and 29.97p

Anyone, please help me.




My PC is like this.

   - Intel® Xeon® Gold 6226 Processor (2.70 GHz up to 3.70 GHz) 12Core 24Threads

  - 64 GB DDR4-2933MHz (RDIMM, ECC) * 2ea

  - NVIDIA Quadro RTX 6000 24GB 

  - 2TB Solid State Drive, 2.5", SATA3, Opal  * 2ea

Hi,

That hardware should easily run that scene in FHD at 30 fps.

You should turn off the Intel processor's Hyper Threading ( SMT ). And if it is Intel 12th+ generation then turn off the E-Cores (efficiency cores) too.
These settings otherwise may cause needless CPU loads on Aximmetry processes and might not be even visible in Aximmetry's CPU performance meter. And make sure your hardware doesn't overheat, which too can cause misleading performance values.
If these settings help, please give us feedback on it. Because we are not exactly sure how many times these settings cause discrepancies in reported performances.

Also, is this 1.52 GHz?

This should show a higher value than your p
rocessor's base frequency, which is 2.70 GHz, and should be displayed here:

It could be that you have some energy-saving option turned on or your CPU overheat, or something else.


When using the Task Manager, turn on Logical processors for the graph view to get a better picture of the situation:
As with almost all software, Unreal can utilize multicores only to some degree.


And when running a cooked Unreal project in Aximmetry, make sure you have Unreal Editor closed and only Aximmetry is open.

Warmest regards,

Thank you for your answer. 

- SMT off. 

- There was no E-core menu on our PC. 

- I turned off the energy saving mode. 


CPU and GPU performance has been improved. 

Frame Rate (FPS) is still up to 30. 

Is there any way to raise it more?

(FPS, CPU, GPU % are the same as the basic level (chair) produced)

Hi,

Something strange might still go on with the CPU. I am not very familiar with server CPU-s, there could be other settings that might be counterproductive.

Also, I am guessing this means Socket: 2 and Cores: 24:

In theory, after turning off SMT it should say 12 cores. Also, I am guessing it says 2 sockets cause you have a server motherboard with 2 CPU sockets, in that case, make sure it only uses 1 of the 2 sockets and it is not mistaken to think that both sockets have CPU.

You could also run User Benchmark's software to see if something is off: https://www.userbenchmark.com/ however, I am not sure how well that software works with server-grade hardware.

Warmest regards,

Thank you for your answer. 

I will upload the benchmark information again. 


The plan is 2160@59.94p for in/out. 

However, we are testing with 1080@59.94p due to FPS problem. 

As in the video, if I check sync, 60 to 70 fps goes down to 30. 

I'm uploading it to help you find the answer.

Hi,

That behavior with the sync is very unexpected. Does it happen with other frame rates or resolutions?
Also, you could try at 4k at this point, as higher resolutions should mainly affect the GPU and not the CPU.

Note that if you have two processors (Intel® Xeon®) in your motherboard, that too can degrade performance as the processors won't be able to efficiently share or use their cache. And in the end, there is a slight chance that you never be able to make it to 2160@59.94p with Intel® Xeon® Gold 6226 cause the low processing power on a single thread, but there are i7 or i9 processors and Xeon W that are significantly faster on a single thread than Xeon Gold.

Warmest regards,
