From 14900K to AMD 9950X3D Is Lack Luster

[The_Cokester]

I want to start this off by saying the 9950X3D has been a performance uplift in other games and general productivity but I was very disappointed to find out that DCS just cant take advantage of the new tech.

Before the upgrade I would be pinned at 90FPS with high settings using quad views. MSAA X4.

Now, with the same settings i cant get more that 40FPS. I have to use DLSS and knock the resolution in Pimax Play way down along with aggressive settings in quad views.

When gaming in DCS I use process lasso to put DCS on the CCD 0 for the V-Cache and that works well but one of the things I notice is none of the cores go above 4Ghz. I just feel like the 9950X3D is not being pushed at all and I am leaving alot of performance on the table.

Anyone got any ideas?

Well, cool.  You just saved me a bunch of coin because I've been noodling that exact migration, which would be somewhere around $1500 by the time I got the new MB.  

Can't complain about frame rate in DCS, apart from the normal 143 FPS to 9 FPS.  The Macro stutters are...irritating.

In the other SimsThatShallNotBeNamed I'm CPU limited and only getting 50-60 FPS.  My 5090 did basically nothing for those because I was also CPU limited on my old 2080Ti.

I have no idea if this will help or even applies to you. I remember a Youtube  vid byJay2cents he does computer reviews and such.  With the newer AMD X3D cpu's you needed to have windows 11 power plan set to Balanced.  If you have high performance it holds back the cpu..  Easy enough to try

If you had a stable 90fps, then why upgrade at all? Did you expect to magically get 900fps??

The 14900k being pretty powerful, you may not see an improvement with VR's framerate cap of 90. But no way in hell will there be a drop in fps.

There is some issue with your PC, plain and simple. DCS with my 9950x3D is silky smooth, except of course when the server itself lags, or Chinooks are near me. In fact I can use the non x3D core to do software encoding for recording in OBS (non VR), with no ill effects at all.

Let's start with some basic questions:

1. Did you perform a fresh installation of Windows on your new PC, or simple insert the old SSD and boot from it directly
2. Did you update the BIOS and chipset drivers?
3. Did you run any benchmarks after building the PC to check of defective components?
4. What is your DCS benchmarking methodology?
5. What power plan have you applied for DCS in Process Lasso, along with affinity?

I upgraded because it was my third 14900K with the intel CPU’s killing themselves. I was just tired of worrying about it. Also not to mention the weird windows update failures, blue screens, and other instabilities. I had just had it with intel.

I did all the recommendations. 
 

fresh windows install

updated bios and latest chipset drivers

other games got increases in fps for sure

because my gaming ssd is separate it has the old settings from when I ran the 14900K

Balanced power plan and tried cores 0-15 and 1-15.

 

the only thing that’s weird to me is how hot this cpu runs. I thought the 14900K was a hot CPU topping out at like 82C

my 9959X3D is getting all the way to 91. I even put a contact plate and re applied thermal grizzly.

i feel like my CPU isn’t boosting at all. Maybe getting to 3.2ghz on a core while playing DCS. I know something isn’t right but I am so confused as to what it is.

Well, if you did a fresh windows install, you also need to undo some things:

There's your answer. In VR the max I've observed is 72-74, 60-65 in non VR. With an air cooler.

Clean and re-apply thermal paste and run Cinebench.

What do you mean with “contact plate”?

I suspect one of these https://www.amazon.co.uk/Thermalright-Contact-Anti-Bending-Buckle-Black/dp/B0BKZM72Z8/ref=asc_df_B0BKZM72Z8?tag=bingshoppinga-21&linkCode=df0&hvadid=80745572594929&hvnetw=o&hvqmt=e&hvbmt=be&hvdev=t&hvlocint=&hvlocphy=41814&hvtargid=pla-4584345041787298&th=1

Ah, ok. Thank you. I wasn't aware of those.
I had the faint suspicion, OP would use thermal pads AND paste together. Which oif course would have explained bad temps.

Nevermind.

Okay. Jesus this will be the third time.

I will try this. Although I think the problem is my CPU isn’t boosting. It’s getting to hot and throttling.

It had a dramatic effect on temps with the 14900K. Like 8-10C drop. So I was hoping it would help with AMD. Will reapply thermal paste and see if that helps.

I have followed all those tips for sure. Which is why I am at a loss for figuring out what is going on.

If you want to be sure that windows isn't interfering with cpu power states, disable the power service completely. With the added benefit of improved latency. (potentially less stutter).

Have you made sure that XMP (or whatever AMD calls it - performance profiles for your RAM) is enabled and working properly? Bios up to date?

I just built a very similar system using the same CPU and motherboard (I'm using the Ryujin 360 Water Cooler, 96GB of RAM and a RTX 5070 Ti OC.) I had a hell of a time getting the motherboard working correctly at first. The first board had to be returned because a of a memory slot issue. The second board initially gave me CPU errors which I later determined was caused by an older BIOS  that came with the board. I had to flash the BIOS three or four times to finally get everything working correctly. I have not changed any settings to memory or CPU overclocking and my CPU at idle is running about 43 degrees Centigrade. When I load a mission or start DCS it might briefly spike up to the mid 70s and then drop back down for the rest of the session.

I would suggest re-flashing the BIOS with the system shut down and see if that changes anything.

Latest bios was installed before I even installed windows. I’m really leaning towards a thermal throttle issue.

It won't matter of you do it 100 times if your technique is wrong. Too much/too little paste will both cause increase in temperature.

Hence my question #3 above.

Watch some videos, try to replicate, run benchmark, and as long as you're within a couple of percents of the expected score for that CPU, you're good

Brother i have been building PC’s for over ten years. I appreciate the concern but I am not what you would call a novice at this stuff.
