My system is CPU bound
AMD Ryzen 7 3700X
GTX 1080Ti
HP Reverb G2

Should I update CPU to 5800X3D or is it overkill with my GPU?

My first build for this sim was a 3700x/RTX 2080 Super  .. I quickly dropped that cpu for a 5900x and that was a world of Difference. However,  considering the Gpu you have in your system presently  and the fact that you are doing VR Im going to say that you should not be viewing getting this chip on the expectation of seeing an immediate substantial performance increase because now your GPU will be holding you back (If it isn't already) . If you don't plan on trying to get an all new platform for the next two years i would recommend getting the 5800X3d + a proper AIO ... That will solve the CPU side of your problem. After that you should be looking to balance your system out with an RTX 3080 level GPU (Plus a PSU upgrade if required) to actually make an impact on the VR.   I guess what im saying is as it stands it appears that your system probably will need a two step upgrade for you to get meaningful results.

Thanks Maxis.

Both the CPU and GPU are holding back, but GPU prices are too high. I will upgrade both, but I thought new CPU as a first aid. In case where the performance improvement would be insignificant then I will wait and upgrade CPU and GPU at same time.

Your cheapest option is to grab the 5800x3d at MSRP (plus an AIO thats very important/ this chip does run a tad hot) so you dont have to do the new chipset /memory /gpu merry go round for a year or two or three depending on your satisfaction level and if your just simming on the pc. You will be left with just needing a GPU and how powerful you need that to de depends on the resolution you want to run . 

VR / 3080ti /3090

4k  / 3080 / 3080ti

1440p + Utlrawide/ 6800xt/3070ti/ 3060ti in a pinch

1080 / 3060 non ti and below  

How does that compare to the Ryzen 9-5900X CPU ?

(Third request).

AMD Ryzen 7 5800X3D - the only (and last) fighter of its kind as a perfect and very efficient upgrade | igor'sLAB (igorslab.de)

I am planning to update from 5900x to 5800xrd. seen enough improvements to justify, but will wait till 2 months from now for the new bios and chipsets. This will let me operate the X570 AM4 for maybe 2 years more.

Id like to see some tests running at 4K in MSFS and showing the dev mode box where I can see the CPU load spikes compared to the 5900x or 12900K. That is literally the true test if this chip is better then another one or not. I could care less about 720p or1080p tests in other games tbh. Show me how MSFS responds to this chip to see if its worth (any?) gains in MFS at 4K.

It's been noted a few times that CPU tests in games are done in low resolutions on purpose to put all the weight on the CPU and not the GPU - which would be the case in higher resolutions. At 4K all the CPUs at the top of the scale are normally the same as the GPU becomes the bottleneck. You can only tell which CPU is best by eliminating that bottleneck.

I am on the fence to upgrade my 7700K to either a 12700K or a 5800X3D and I am still unsure which one to go for. I will be going into a new platform anyway, and I am aware the AM4 is dead, but if I keep the new one for another 5 years like I did with the 7700K then it is a moot point anyway. I was looking at 5900X which is going down drastically in price but if it is beaten in MSFS by the 5800X3D then I can stretch to that price point (cannot justify the cost or cooling requirements for the 12900K). Eagerly watching this topic from other X3D buyers to decide 🙂

Well. MSFS is different than other games though.

I run 4K Ultra with a 5900x and a 3080ti with watercooling. 
 

And on ground I am CPU-limited pretty much all the time. So yeah. Also in 4K, in some scenarios, the 5800X3D may be better. 
 

But I personally would never sidegrade from a 5900x to a 5800x3D as there are only some games that profit and you loose cores.

If only this were true in MSFS, but it's not. The question Wiler asked is a good one. Everyone is focused on FPS, but, that is not what he was asking. Frame time is far more important, and he was asking if it is smoother at 4k with this cpu. Does it produce better frametime? At 4K with a 3090, I am still main thread limited in 75% of scenarios, so, anything that alleviates that or helps with the frame time would be amazing.

All of the testing I did and listed was in 4k with a 3090. The Mainthread was on average 20ms for the 5900x in developer mode and with the 5800x3d it dropped to 14-15 ms.  I saw 10+ FPS in pretty much every scenario on the ground. However, it doesn’t lock a perfect 60 so panning left and right will do the same drop and increase. If you lock it at 30 FPS it’s just straight green in that developer window with the occasional yellow from the GPU. If you plan on loading up track ir and having a Tom Cruise in a dog fight seizure of left to right movements with your head i doubt it will be perfectly smooth unlocked from a sync’d fps.

This post has 4k demonstration vs 12900k and also a vr assesment video which discusses the frame timing.

exactly. I found out that for me  (5900x+3080, 32gb ram 3800mhz) locking frames @30fps has made the sim mostly smooth and almost stutter free. However there are times when the CPU gets hit hard (big airports) and frame time spikes big time causing stutter to show. even tho the frame time improvement seems notcieable from what i saw in that vid posted below and the report from travel runner, im just not sure spending another 450 on the chip is good value for money over a 5900x right now. Im going to wait for the ryzen 4 chips coming end of the year and see how this measureup and then see if its worth the upgrade.  mind you a new motherboard will need to be purchased because am4 is being retired. I think those on the 3000 series should find this 5800x3d to be a more logical upgrade then someone from a 5000 series chip. 

I wish the LOD would dynamically reduce from 200 to 50 when I descend below 2000 ft AGL. Then I would have great fps gate-to-gate. Of course reverse this when departing. 
 

I guess the graphics engine is not capable of changing this on the fly 😞

Maybe something you can suggest in the forum and have the community vote for it.

Hi everyone. The discussion here provided me good background to attempt the switch to the 5800x3d. Did it yesterday and the results for me was good enough for the cost. I came from the 5900x and it cost me 100usd to make the jump, selling the old processor. Frame consistency is better and noticeable. Other than on the ground at major airports near photogrammetry areas it’s almost a constant 55+ fps at 4K Ultra or even 60fps flying simpler airplanes downtown LA or NY, something I haven’t seen before with the 5900x. So I’m more than happy. There’s some optimization needed in the sim when on the ground. Taking off from LAX for me, climbing above 100agl just clears everything and it frames move up to what the gpu can give.

running it with a 3090ftw3, 32gb of cl14 3600 and a fast nvme. SMT off, way more addons than I should. If anyone wants specific data from a certain location let me know and I’ll try to help you.
