Looking for a CPU Better Than the 9950X3D

[IAF.amir]

Running a 9950X3D with a 5090, and the CPU is maxed out at 100%. I also have several screens connected.
Is there a better CPU on the market?
Would switching to a server type CPU help?

when you say it's maxed out ... at 100% what exactly do you mean ... a single core might be maxed out, but you wont be using all the cores at 100% that's just not the way DCS works on something like 9950X3d but functionally no there is not a better CPU on the market... but several things come to mind... 

 

1) are you sure that DCS is actually using the correct CCD, the 9950x3d has two CCD's only one of which has the improved ram cache 

2) are you overclocked, what's your cooling solution/temp

3) have you disabled core parking 

4) have you submitted your dcs.log to the bot on ED's Discord channel, it normally is quite good at diagnosing problems

1) what is CCD ? cores ?
2) not overclocked, water cooling
3) is in the BIOS ? how to do it ?
4) ive tryed that, can try again

*X3D Turbo Mode is enabled

that's very strange... for a number of reasons, the 9950x3d  has 16 cores you only have 8 turned on , and you don't have hyperthreading enabled so there should be another 16 virtual cores ... i'm not sure why you have two GPU's either ... and additionally whats your cpu usage when DCS  is not running ? because that is really really odd... you say you are not OC'd but you are running at 5.39 which feels like you have set a PBO ... honestly i'm not even sure where to start

1)The 9950X is a dual-CCD (Core Complex Die) processor, meaning it has two separate dies, each with its own set of cores.

CCD 0 is the "preferred" die for high-frequency performance, boasting a higher Fmax of 5.75 GHz compared to CCD 1's 5.45 GHz.

How to Assign Cores

Use Task Manager:

Open Task Manager and go to the "Details" tab. 

Right-click on the process you want to optimize and select "Set affinity". 

In the dialog box, you can manually select which cores the process will use. To prioritize CCD 0, you would select the first 8 cores. 

As speed of heat noticed, somehow you are missing half your cores. Disabled in bios? If not, update your bios.

3)To adjust CPU core parking, you can use third-party utilities like ParkControl by Bitsum or Quick CPU by Coderbag. 

 

Also, run Process Lasso to optimize your cpu in real time

 

Is IAF Israeli air force or Indian air force?

You’re only using a quarter of your CPU. And why on Earth would you use 2 graphics cards, and dissimilar ones at that?

For DCS that is no longer needed, and may in fact reduce performance if you set it up wrong.

For reference, I run my 9950x3d on an air cooler with no problems

x3D Turbo mode disables the non-x3D CCD and SMT too I think, so Windows sees fewer cores

What I find interesting is that you have 2 GPUs and both are being utilized. Unless you know why that's happening, I suspect you might have a malware mining on your PC

Also if you don't have VSync enabled, or have the FPS limiter at the default 180, then 100% CPU usage is expected given you have a 5090

hmmmmm.... I guess 10950X3D

There is no better CPU. Server-type tasks tend to consist of lots of work that needs to be done in parallel, but not necessarily superfast. That is a very different use case from games, and games are not going to run optimally on such a chip.

But I agree with the other people that you have very weird load that doesn't seem consistent with just the game putting load on the CPU. It's not normal for games to fully saturate all cores.

Can you post a picture of the performance view when DCS is not running?

I have to agree, both accounts.

It looks like that chip is capped and running running DCS with 8-cores and 8 threads only (SMT off seems to be the issue, it shoud be 16 threads being pushed - game running in one CCD only is normal). Giving a look at the BIOS to ensure all cores and threads are enabled would be the first step. Try disabling X3D Turbo Mode (if that's enabled) and see how it goes.

The other step would be to run DCS with a capped framerate (more so if w/ G-Sync capable monitor) - it makes no sense to run DCS at over 120 FPS, regardless of potent hardware.

You don't specify motherboard model.  This is where to start.

Detail is needed on the computer: Self built?  Or prebuilt?  Is it new, by chance?  (In January this year, you indicated having a Z790/14900k system, with a 4090... so it appears you have changed since then).

Download and run CPU-Z, to determine current BIOS version here: https://www.cpuid.com/softwares/cpu-z.html  This is a very reputable, safe app.  There are other ways to check BIOS version, but CPU-Z will offer additional information that will be helpful as well.  Post a screen shot of the first three tabs (see example below).

Likely the machine needs a BIOS update; this behavior could easily be due to out-of-date BIOS which doesn't properly support the CPU.

Are you running AMD's Ryzen Master by any chance?

CPU-Z tabs:

(PS Also need info on what the 3060 GPU is doing there...are you trying to use it as a Physx device?  Or maybe for the Lossless Scaling app? I'd try running it without, just as a test).
