DavidE Posted December 13, 2023 Posted December 13, 2023 I am close to upgrading my 9900K PC, already have a 4090, play mainly VR (looking at the Somnium when it comes out). If I was playing DCS / games only, I would go with the 7800X3D. I also do astro imaging processing which is extremely CPU intensive, processing can take 12 hours, with a higher resolution camera could be 24 hours on my existing kit. I am therefore looking at the 7950X3D as a compromise solution. Does anyone have any experience with this CPU for DCS VR gaming, wondering if the higher boost clock of the 7950X3D gives any advantages. I am aware that the 7950X3D can be a bit more temperamental but its an (expensive) compromise. Will be aiming for 64 Gb of memory.
edmuss Posted December 13, 2023 Posted December 13, 2023 The only issue that I know of is to do with core scheduling, this may not be a problem now though. From what I understand, only half of the CPU has access to the 3D cache so you may want to force DCS onto those cores.

Thanks, that’s the issue I am trying to get some someone with real world experience to advise on.
Raven (Elysian Angel) Posted December 13, 2023 Posted December 13, 2023 From what I hear (I don't have first-hand experience), core scheduling is an issue in general for gaming - not just DCS. If you really want the 7950X3D, I'd recommend using Project Lasso to limit DCS (and all other games) to the CCD with the V-cache on it. 6 hours ago, DavidE said: Will be aiming for 64 Gb of memory. I'll assume you mean 64GB? 64Gb is far below the minimum system requirements for DCS Spoiler Ryzen 7 9800X3D | 96GB G.Skill RipjawsM5 DDR5-6000 | Asus ProArt RTX 4080 Super | ASUS ROG Strix X870E-E GAMING | Samsung 990Pro 2TB + 990Pro 4TB NMVe | VR: Varjo Aero VPC MT-50CM2 grip on VPForce Rhino with Z-curve extension | VPC CM3 throttle | VPC CP2 + 3 | FSSB R3L | VPC Rotor TCS Plus base with SharKa-50 grip | Everything mounted on Monstertech MFC-1 | VPC R1-Falcon pedals with damper | Pro Flight Trainer Puma OpenXR | PD 1.0 | 100% render resolution | DCS graphics settings Win11 Pro 24H2 - VBS/HAGS/Game Mode ON
Str][ker Posted December 14, 2023 Posted December 14, 2023 Hi, I have the 7950X3D, 64 GB of DDR5 RAM, 4090 GPU, etc. I have no issues with DCS. Eagle Dynamics have core scheduling built into DCS so I no longer need to set affinity (I use Process Lasso) for DCS. I still do set affinity for my VR headset (Varjo Aero) and all other processes though. I put the VR related processes on the better performing CCD to (in theory) optimize performance. I have posted videos of my time in DCS VR using this system (pretty much all of the videos this year and on) so you can always have a peek at them. I play around with settings still to tweak my experience. I'm very happy with the results. I'm happy to answer questions which you may have. https://www.youtube.com/@StrIIker-TV
