90 Hz is the LED refresh rate, but the image itself does not refresh at 90 Hz, no one is getting 90 fps in VR in MSFS at 2kx2k resolution. 😍

Turbo, that's incorrect. 90 frames per second is the native refresh rate of the Reverb G2. Meaning that that is the frame rate that you would ideally want for maximum smoothness. What I'm saying is that's one example of why one would want more than 60 FPS.

Obviously most of us don't get 90 frames per second in normal use, which is why reprojection is a thing. Reprojection is very helpful, but it's just a stopgap until we can actually reach the frame rates that we would ideally want (90 for the Reverb G2, 120 for the Valve index).

I don't know if smoothness would be greater with a headset that was designed for more than 120 FPS, but I suspect so.

Aerofly FS2 will actually let you get the 90 frames per second to match a G2's native rate. MSFS is not so well optimised for VR, so good hardware is needed even to hit 45 FPS (with an RTX 3090, I was getting 21 FPS at IniBuilds EGLL with no traffic) . But if you can get 90 frames per second, that is definitely what you want.

Do you think the CL30 is necessary/helpful for MSFS?  I’ve been looking at CL32, about $80 cheaper for me than the CL30.

I'm actually looking at lower freq memory with better latency since X3D isn't really affected by mem clock speed.  --  DDR5 5600 CL28 was one kit I looked at.  But I haven't specc'ed out what is on my motherboards QVL list yet.  Really for what is on the QVL will guide me on the memory.

Yes, unlike sims, it's unlikely that you're average flight sim enthusiast will buy both an i9-13900K and an 7800X3D so a comparison is both valid and useful.

But this isn't really an Intel versus AMD thread. It's more about where the upcoming 7800X3D fits as a MSFS CPU, and the competition is other X3D chips, not an i9.

I'm flying Intel right now, and have been a proud Team Intel member for as long as I can remember. I did a build with an AMD chip back in the 90s, ugh, never again...

Until these new X3D chips came out, which are clearly better for MSFS then the best that Intel can do. I've talked to my therapist, worked through my past AMD traumas and am now ready to build an AM5-based system. There's plenty of reasons to buy an i9-13900K, but If we're talking peak MSFS performance in April 2023, I think it's got to be an X3D CPU that goes in your system.

Nevermind the fact the 7800 will run much cooler than a 13900 as well while giving better performance.

That's not a theory anymore.  Gamers Nexus tested this and both 7950X3D and 7800X3D varied between 4.7-5.1 ghz depending on PBO / Optimizer settings.

It's all so close anyway, that it is within the margin of error, and you're talking a few fps in MSFS when you're already getting say 80+. 

 

The theory I referred to was referencing people claiming why the 7800X3D should be faster than the 7950X3D in MSFS.

My point is that the best and most relevant tests - which I linked in an earlier comment - say that it's not, so a theoretical argument that it should be is pretty meaningless!

The 7800X3D is a great processor for MSFS and it's pretty close to the 7950X3D, but - based on the current dataset - it's not "the fastest CPU for MSFS" as claimed in this thread title.

I understand that RAM speed is not that important with the 7800X3D unlike with Intel 13900K, which doesn't surprise me considering the CPU will work mostly off it's cache, which is ca. 7 x faster than the fastest RAM. the question is to go with the new $ 85 A620 chipset or the beefier X760 if you can ignore PCIe 5 and get by with PCIe 4 instead, since no GPU uses/needs/benefits from PCIe 5 anyway,

I went ahead and got a board with PCIe 5.  I may use it someday.  I may not...

I does bother me a little bit spending almost $500 for a motherboard with Q-code display, but that's how it is today.  But the good news is there are much cheaper AM5 motherboards out now, and even some of the B650 boards would be just fine for sim use.  I almost did that (went for a much cheaper board) but in the end I decided I probably would keep the machine for 5+ years and it's only money.    Money for flightsim = money well spent I say.

For those buying a 7800X3D or 7950X3D, what Mobo did you go with? 32 gig or 64 gig of ram, and what speed/CL did you choose?

My current plan:

ASUS ROG STRIX X670E-E Gaming WiFi AM5 ATX Motherboard

64 gig of G. Skill Trident Z5 Neo RGB 32GB (2x16GB) DDR5-6000.

My computer company purchased this setup today for my 7800x3d build:

ASUS ROG Strix X670E-E Gaming WiFi Ryzen 7000 ATX

G.Skill Trident Z5 Neo RGB DDR5-6000 C30 (2 x 16gb)

The Mobo chipset you want is the X670E, if you're going with a fast CPU I think you want the Mobo to get the most out of it.

Thanks Eric. That's the MoBo I mentioned earlier that I was planning on getting, I think it's a strong choice. The Gigabyte Aorus Master is my 2nd draft pick.

As per my earlier question to GC - any reason for the C30 or is that a random choice? I'm looking at going C32 because it's cheaper, but I'm willing to be convinced otherwise!

Perusing various forums and subreddits, C30 is the ultimate sweet spot for the x3d.

I went with the Asus ROG Strix X670-E

As I said though, I could have gone cheaper and been pretty close in performance.  

That seems to be a popular board for these builds based on what you guys are posting.   I almost went for an MSI Carbon board but in the end I went with my tried-and-true ASUS board.  I think their Intel LAN issues are well in the past now.

I'm just a humble i9900K owner who, like may of you reading this, wants some quality information to help me make a wise choice for my upcoming CPU upgrade.

coming up shortly, first orders should arrive next week. was confirmed by my store: 2.000 units will arrive mid next week. then this forum will be flooded with the most detailed MSFS benchmarks that Paul's Hardware had no time/knowledge how to properly test.

So, I can actually get a 7800X3D in about a week, which is sooner than I can get a 7950X3D.

The $64 question: Is there ANY review other than Paul's that shows the 7800X3D outperforming the 7950X3D in MSFS? I've been looking, and so far I haven't found any. So it's Paul (external view only) vs Eurogamer and Tom's hardware.

I'm genuinely interested in any further data, because I'm ready to drop the hammer on this, either way.

Sure, sure - but who wants to wit an extra week? 🙂
