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?
