here is the test from Toms H that turbomax linked to, if you read the 7800x3d test you see this, and my tests with booth cpus is very close its 7-8% diff

Iam not blind i clearly see the difference, but if you not tested booth it can be hard to know

A 4090 at 1080p is a waste.

1080p is a waste. that video is a waste. 😃

1080p is for removing all GPU bottlenecks...

You will be able to load more AI and set a higher T-LOD value with a 7800X3D, that's it, your 4090 will take care of the rest ,but the question is if you need to upgrade your CPU now that Auto FPS has become a reality, it seems to work fine from what I understand.

Turns out FG became significantly better now w/ 7800X3D over the 9900K.  What's happening is I'm able to run native at 45 or so in complex scenarios instead of the 36 or so with 9900K.  Artifacts in FG were worse with the lesser CPU as well.  What this translates to now is I am able to run at a native rate of 35, doubled to 70, and there are no stutters anywhere now at least thus far.  Render Scale at 150% seemed to be adding some stutters w/ the 9900K and those are all gone now.  The sharpness and detail from RS 150 plus LODs higher (while above ground, still keeping controlled on the ground) has really made a significant improvement over what was already really good.  Runways on approach are much clearer/sharper, AI planes in the distance, stars. etc, much improved.  So no doubt the strong CPU/GPU/VRAM is what it's always been touted to be, the best solution if you can afford it.

Yes it is, this is how the game should work for everyone, hope it will be like this with less expensive hardware in MSFS 2024.

So Noel are you saying that you are only getting a 25% increase in FPS by by moving from a 9900K to a 7800X3D.  I was under the impression that your would get a 100% increase with that upgrade.

That was never my impression I looked at single thread and multi performance and it is about in line with expectation, +25%.  In this sim it's probably more than 25% but as I lock rate at 45 or so now that's good enough when we're stutter-free.  Right now I'm in the FBW 320n and locked at 45fps at another KORD gate, whereas wide open it's 78fps, but haven't loaded FSLTL yet.  My former locked rate was not quite there.  I would need to lock at KORD at around 33 or so in this plane, so 45 is a meaningful change as that is in the realm of much greater doesn't add much compared to the diff between 34 and 45.  TBH, adding 4090 was the best move here, and that is w/o using frame generation.   The added VRAM and running Render Scale at 150% really made a nice difference visually.  Had I not needed to move the 9900K into a different role I would not have done the upgrade.  7880X3D was also chosen for its modest cooling needs as I prefer air.

New CPUs GPUs and MBs releasing this year, Intel dropping HT in the yet to be released CPUs Less heat better performance could be the reason. Will have to wait and see the benchmarks.

Hmmm on looking at this again you might be right.  I am going have to temper my expectations for a CPU upgrade induced FPS boost.  More reason to hang on to my 9900 for a bit longer but like you I have another use for the 9900 so I am going to have to upgrade at some stage over the medium term and yes upgrading from a 3080ti to a 4090 has been one of my better hardware purchases as much for the doubling of VRAM as for FG.

Interesting I have been waiting for info on where Intel is going with their new CPUs.

Or not...!

I realized last night on one of the failed reboots I had to pull the BIOS battery to reset it completely as the jumper didn't do it, and I had forgotten to disable hyperthreading, called "SMT" in AMD world.  Since then the rate has gone up a bit more, to very close to 30%.  At FSDT's KDEN yesterday native rate approached 80fps.  By the time we were taxiing it was around 62 or so, and that is at least a 35% bump over 9900K.  But the reality is here, for reasons I can't understand, frame generation has turned out to be a net loser.  Too much graphic aberration, panning is no better or worse, and I have no idea why.  When I ask others they can't relate it leaves me wondering if MY new RTX4090 is the culprit, or something else.   The VRAM is just was need, loving the 150% Render Scale, its raw processing power far exceed the former 3080Ti, but as I say FG really fails here.  If it did I would love to run at a lowly native rate of 30fps x 2 is 60, but the graphic anomolies are for me too hard to ignore.  As I say others can hardly relate though clearly others also report some aberrations there too, but few end up disabling FG as I have done.   I can't tell if others are so enamored  w/ frame rate they learn to ignore these aberrations, or not, no way to tell!

Well I can't help you with your FG issues - I also have my display extended over a second monitor but don't see the FG artifacts you describe. Perhaps the problem lies with the monitors you are using - do they both have the same resolution and aspect ratio?  I have a 40 inch 4K Phillips monitor and a 49 inch 4K Sony TV both circa 2017.  I run MSFS2020 on the Sony TV and Little Navmap, Simbrief etc on the Phillips.

It's possible it could be related to the monitors being used I though about that.  So I did a test to rule that out last night:  I disconnected the 2nd screen.   Unfortunately the artifacts were just as prominent.  There is some things I just can't follow on this.  I did this once before, removed the 2nd screen, and the issue seemed to disappear.  One reason is that it is very lighting sensitive.

This evening I started a flight at FSDT KDEN in the PMDG 738 and native rate was 80fps before engines running etc.  By the time I was taxiing after GSX pushback the native rate dropped as low as 43 once but was generally hovering around 46 to 50 or.  At that point I thought I would yet again try FG and voila, vastly improved w/ regard to the artifacts described.  90% improved, now roughly comparable to native though not quite.  This is a known issue w/ various revisions of Nvidia DLSS which is now headed for DLSS 4.  Usually they are working on techniques to improve image quality that is the challenge.   With version 3 it is very good for most, and why it suddenly improved here isn't clear.  Perhaps it was the into the sunset lighting flying east to west to Salt Lake City cancelled these aberrations out.  But even the typically bad with FG enabled FMC white text was vastly improved.  I made a few changes in Windows display settings maybe something done there helped.  It's been a little this way where one scenario it's very bad, then out of nowhere it's much improved, then bad again.  Anyway the tech is being further developed and I'm sure we'll be completely free of these types of issues sooner than later.

I'm pleased w/ the 7800X3D.  It's generating, along w/ 4090 of course, perfection everywhere with room to spare.  Are you running Render Scale at 150% or above?  It and higher TLOD have really amped up detail and sharpness.

The 9900 will be a significant bottleneck with your 4090. A 4090 gives you some significant future proofing for sure but you would get way better performance today, for the same money, by rather buying a 4070TiS and a current top of the range CPU from Intel or AMD, plus a new motherboard and DDR5 RAM. That’s because even an i9-14900K or AMD7950x3D is going to bottleneck a RTX4090 in MSFS2020. Even with a 4070TiS, these top tier CPU’s are the bottleneck because of MSFS’s single thread reliance.
