How many CPU cores does Trainz actually need?

[AV3]

So I am trying to decide between AMD's 9800X3D and 9950X3D Processors. The 9800X3D has 8 Cores while the 9950X3D has 16 Cores.

Running TS22 nothing special in driver 14% CPU Xeon 8 cores 16 with hyperthreading, 38% GPU rtx 2070 and 4,000+ threads. Surveyor is different.

Reality I don't think the slower CPU will affect real life performance but I'm certain that someone will create content that hammers the CPU and the faster CPU will do better.

The Ryzen 9 9950X3D is priced around $700, while the Ryzen 7 9800X3D is available for approximately $480, if your primary focus is gaming, the AMD Ryzen 7 9800X3D is likely the better choice due to its excellent performance and lower price.
The 9950X3D, while slightly more powerful in some gaming scenarios, does not showcase a significant advantage over the 9800X3D in most cases, especially at higher resolutions where GPU performance becomes the limiting factor.

With an i-9900K (8 cores), Trainz only uses 2 threads intensively, others being used as of below 10%.

But they are being used which makes answering the question difficult. On a build regardless of cost is one answer, the other from a practical point of view, you won't notice the difference is the other.

Ram and gpu seems to be the most important. The 8 core cpu should be plenty for your needs. my cpu always sits around 25% during game play. The only time my cpu is really hammered is during installing 3rd party add-ons and during a database repaires.

Suppose it's worth noting that the 9950X3D is meant to be more as a workstation processor rather than just a gaming processor like the 9800X3D.

I purchased the Asrock Taichi X870E $469.99 with a free gift of the WD Black 1T M.2, and the AMD Ryzen 9900X CPU for $374.73 a lot less than the 9800X3D back several months ago. The X3D is not worth the extra cost as it is only a few % diffrerences in the Performance.
Good thing that I got the parts before they want back up an cost.
The performance is vey good smooth frame rates on my large Map compared to the Ryzen 5900X.
Trainz looks as it is using 6 Threads from what I see in the Windows Performance Monitor.
