Question DCS VR Build

[goobernoodles]

I currently have a main computer with a 13900K and 4090 that I play mostly FPS (Chivalry 2, CS2, OW, etc) and RTS games on. I've thrown thousands of dollars into planes and hardware (Winwing Super Libra & Taurus HOTAS) for DCS but it's been collecting dust. I have the room for a 2nd PC and am seriously considering buying a monster tech MTS sim pit setup. This would, however mean I need a 2nd PC.

I'm looking for input & opinions on the following build: https://pcpartpicker.com/list/K39mWt

First and foremost, I am building the PC for DCS. Anything else is secondary and shouldn't really matter. I would say 2k is my budget for this rig. I'm located in WA state. Generally lean towards Intel & Nvidia, but that isn't a hard requirement. I don't plan on overclocking. As far as resolution goes, I plan on using my Valve Index for the time being which would be 2880×1600 from what google tells me. I also purchased an HP Reverb G2 which had some amazing clarity, but I hated the Windows Mixed Reality hoop I had to jump through. Either way, I'll probably try both. The bigscreen beyond looks intriguing as well - something I may shift to.

I don't particularly NEED to build this now if some earth shattering new generation of CPU's is about to come out or something. The bigger purchase is going to be the monster tech setup.

One possibility to keep in mind would be using this build as my FPS gaming rig and using the 13900k/4090 setup as the VR rig. Open to any suggestions.

New AMD CPUs are rumored to be coming out in April. It is unknown yet how much faster they will be or if the 3D VCache version will be one of the early releases (it has not been the previous 2 times it was released). That said the AM5 platform will support the current gen CPUs and the next release (and possibly a third generation released in the future).

If I'm not mistaken the 3D VCache CPUs are the best performing CPUs for flight sim. And flight sim is much more difficult to achieve higher frame rates than the FPS games you mentioned. So I think you would be better off to pair the 4090 you already have with the 7800X3D in a new build for DCS, then use the 13900K and a new GPU for your FPS rig.

Since you want to use a VR headset, you would need to get minimum 4080 Super for the DCS rig.

This benchmark result shows that turning SMT off on the CPU results in smoother performance in DCS VR: https://forum.dcs.world/topic/320858-multithreading-vr-benchmark-4090-7950x3d/

Thanks for the input - the more I think about it, pairing the 4090 w/ a 7800x3d seems to make the most sense.

The X3D doesn't seem to help DCS much. You could go with a cheap 7500F for the time being and then upgrade to a beastly Zen 5 CPU later in a few months.

DCS performance has been terrible after the deferred rendering I think it was since 2.5. Prepare to be disappointed in the performance even after spending several $K on a top of the line system.

12700k, 6900XT, 64GB DDR4, HP Reverb

I haven't played since multi threading released. Between that and DLSS being added, I would expect a huge increase in performance from the pre-MT days. That's not what you've seen?

It's decent now, but as the units add up to make realistic scenarios the performance still tanks-- especially on crowded MP servers. MT hasn't really helped a whole lot so far, and some guys are still using ST because they get better performance/less stuttering somehow.

IL2 BoX runs much better so I play that instead for my WW2 MP fix.
