Here's a good comparison between the 12900K, 12700K and 12600K in MSFS.

And, as expected, the i7 is the sweetspot of the novel alder lake CPUs. 12900K has not a lot of benefit for the higher price tag and 12600K is a little short with only 6 P-cores. 

Double post, sorry

I'm just not understanding how accurate that 1080P bench can be....    there's a miniscule difference between the flagship intel cpu and the 12600K.  .

The difference is only due to larger L3 caches and frequencies. The bottleneck with MSFS is always the single thread performance. Yes, in 2022.

The Ryzen 5900X or even the 5800X are the best choice right now, budget/performance wise.

Hopefully this eventually changes with the move to DX12.

Yeah but not with "DX12 Early access" in November... they need to make a new build with new code. When we'll see a DX12 release where DX12 cannot be switched on / off, then we can hope in major changes.

Exactly....that's why I used the word 'eventually'😉

take a look at the low 1% FPS, and frame timing with the 12900K. It seems that it eliminates a lot of cpu stutter.....That would be enough for me to upgrade...

This for me is one of the most important points being largely overlooked. I recently returned a pre-built PC due to exessive stutter from which I realised that smooth gameplay is just as important as higher fps, if not more.

Personally I am waiting to see if Alder Lake can deliver this over just having 10% more fps.

Yup, if it spews out the same FPS as the 9900K and 3090 I would be ok with that, if it completely eliminated any left over CPU stutters. That to me, would be worth the upgrade.

So after watching that I sprung the extra $75 for the i7 combo over the i5 combo.  Whereas Frame Time was consistently with .5ms between the i7 and i9 there were drops where the i5 was almost 1.5ms slower. 

If the extra $80 gets that extra bit of fluidity it is worth every penny.  I will keep my 2080, DDR4, PSU, HDD's and M.2 and just move to the new mobo/CPUcombo. 

My wager is I will get as much in terms of performance gains out of a $600 full CPU and Motherboard upgrade combined with my G-Sync monitor than I would dropping $2,000 on a GPU only!  

I'll report next week on the gains.  I'm coming from an i9 9900K so if I see a performance gain even in terms of fluidity no doubt those with a lesser CPU will as well.  I'm also very close in a lot of situations to being right at 60FPS natively and relying upon G-Sync to smooth it out.  This could eliminate the G-Sync in those situations I only needed a few more FPS to maintain a steady 60 FPS on my monitor set to 60Hz refresh.  (I don't need 120)

Paul-

i suspect you aren't far off... I went from a 6700k at 4.6 to a 11900K stock and from a 1080Ti to a 3080Ti.  This was done in stages with the CPU first as we all know about the GPU shortage.  The performance with just the CPU upgrade was within 20% of the final total performance.  Please note this is "felt" performance as I've never bothered with benchmarks.

It's great to see you active here!

Ta Carl, hope you are well!!!   Great to hear from you!  

In the past sims we were mostly always CPU bound.

With MSFS it's always GPU bound (my system) and to that we can add internet bandwidth bound.

That sounds like a very good deal. I also believe the 12700K is the sweet spot. Going to be a killer system.

Looking forward to hearing the results!

Thank you and thank you to everyone for all the information in this thread!  Turns out Newegg shipped from NJ and everything should be here tomorrow.  Enermax even has a $9 LGA1700 adapter for my current cooler to make things that much easier... This will determine if I really need to invest in a GPU.  With G-Sync my 2080 and this CPU I may not even need the massive $2,000 hit of a new GPU.  

Edit:  I took the hit 😂  Just as I typed I may not need a 3080ti I got the notification to buy one at MSRP.  So yeah.  I lasted all of 3 minutes.  Anyone need a 2080 😉
