So, first results with the 13700K and 4090 that replaced my 12700 and 3090 with my usual test-scenario (SU10, DX12@4K@mostly Ultra, KJFK, 31L, 12:00, Overcast, PSTX+RT Traffic, Fenix A320):

12700 + 3090

13700K + 4090

So, without DLSS3 and using SU10, the gains are around 25%, even though I did have more live traffic on my second test.

Other games and benchmarks that I've tested tell a different story (50% and sometimes over 100% increase on performance), so I am quite happy with this upgrade.

I also use PSTX+RT Traffic and my tests are in KJFK. We must recognize that PSTX+RT Traffic puts in real heavy traffic (Real) which causes FPS to plummet to around 20 and 25 without DLSS3. Already with DLSS3 in my case it goes up to double 40 or 50 FPS. But if we remove PSTX+RT Traffic, it goes up to 90 or 120 FPS.

Is anyone finally able to record a video? I would like to see DLSS3 with Heavy traffic on heavy airport.

It’s the Live Traffic. Although it is updated 30x per sec MSFS can’t make them appear completely smooth.

The 4090 indeed is more powerful than the 3090. Will give you 7/8% more fps in TAA mode. However when using DLSS 3 it doubles the framerate of the output frames.

My 12900K is now the culprit …

It's like a dog chasing its tail -- and can never catch it tail -- you upgrade the video card, and now you could upgrade the cpu.

A constant FS truism over the year:  We all want flight sim Nirvana and it always seems so elusive...

Setup=>enable frame rate limiter. Then framerate limit = 120 in the main window. Not getting any of the stutters and stuff that Digital Foundry got with v-sync doing it this way. 

Btw, have you got your 4090 up and running?

Actually, now that we have high frames, I think I will just revert to G-sync, as it gives by far far far the smoothest experience available. I only stopped due to dips below 40fps on my Lg-C1, casuing LFC to kick in, but that should no longer be an issue with DLLS3! So, another win there...! Do not have to mess about fixing frames that way either. DX12 with G-sync and high but even fluctuation frames = heaven.

Is the stuttering a sync issue (VSYNC etc.) ?

Some fps will also get eaten by the video capture itself. It's not insignificant either, especially if recording at high quality, hi-res, hi-fps.

Tried, didn't go down too well. Think I've elaborated on it somewhere (just can't remember where, lol). 

Even a 1080p video capture will keep hammering away at the poor mainthread in these already marginal scenarious. I can't make it work properly without an external video card. 

The videos (Fenix, EGLL, KLAX) are in a thread over in the monitor subforum. I think. Just take it with a grain/bucket of salt as the capture introduces stuttering that is not there in the sim. So basically it's pretty useless.

Yup. G-sync to prevent tearing below max refresh rate, then RTSS frame limiter to prevent tearing above max Hz. I find that's the best solution. IMO of course.

That is an apt analogy.  I think it is driven by the priorities one has driving their decision processes.  And of course their personal criteria for what constitutes Nirvana for them.  There is a steady supply of software addons and features that people can't wait to install and implement and this taxes their previously capable system to the point hardware upgrades become the main path forward, ad infinitum, more or less.  It's a hobby in itself, much like building forts or playing army with toy soldiers was when I was a wee lad:  the fun was in the building.  Once it was all done, interest began to wane.  For me FS is different in this aspect:  I fly primarily to try my hardest to score well on APLv2's scoring feature, roughly monitoring my piloting skills.  This provides that "purpose" such that it continues to satisfy or frustrate as is the case now w/ this plane as I am having a hard time landing w/ the requisite FPM and g-forces to stop triggering penalties!  

With the current BEST visuals MSFS can offer anyone regardless of hardware, I'm already there pretty much.  Upgrading my CPU is a possibility, and that only to allow better attenuation of perf degradation at arrival airports.  It's a lot better already in this regard but it seems 7900x or 13900K will largely fix this remaining area for me.  If n when Asobo amps up the quality of cloud depiction or satellite imagery that may change the picture for everyone.  I sure hope they do as I would have no qualms about upgrading to the best possible hardware to allow for this.  But that isn't happening now and it is not in sight that I know of.

I have regained nearly 100% flawless stutter-free animation once again after a few months of loss of that.  I already have "smooth" per my perception and the only animations that ever stand out to me are the now rare stutters.  I just now TO at FT's KLAS in the PMDG 738 with a lot of RT online traffic (w/ ST's funky liveries), but it wasn't too heavy for my settings which are maxed save TLOD which was at 100:  I saw maybe 2 really short hitch/stutters from gate to altitude.  They were so subtle as to be irrelevant anyway.   As is always the case landing will be a slightly different story but since it's KRNO it may be flawless, we'll see in a few minutes.

So I'm pretty much already in Nirvana with the only caveat being I'd really like to avoid the frequent but minor loss of perf at the arrival airport.  Right now it's well better than it's ever been and DX12 may be helping with that.  I wonder if there is more optimization of DX12 coming...

I have setup my amount of parked ac in PSXT in the way that at major hubs with bad weather I stay at 31 minimum.

For EHAM that means 44 parked ac + Live Traffic,

I remember when using my 7940x cpu I had parked ac at major hubs limited to 25 parked ac.

Calculating all AI ac seperately with moving parts put a heavy load on the cpu.

What is good about DLSS3 is that it doubles the frames by putting ai frames between the real frames. That reduces small stutters and jitters by half. So the PSXT ac are moving quiet smooth now.

Have you seen any difference between

DLSS = DLAA or

DLSS = Quality?

I cannot identify any difference between the two. What do you think is the best alternative?

TAA = best image quality. Can be combined with frame generation = double fps. 

DLAA: Quite good image quality but jagged edges

DLSS Quality: More blurry than TAA and DLAA

DLSS Performance: Too blurry on my 4K OLED

As I'm not GPU-limited with the 4090, I don't see any need for DLSS. Hence: TAA + frame generation.

If I use DLSS + GF Exoeruence filters where I also set sharpness to 10% the framerate stays the same and the image is much sharper…

Agree. DLSS quality is not bad at all with a bit of sharpening added. I recommend trying TAA + frame generation though. 

Happy with the 4090 so far? I know, you've only had it up and running for a short while. 

I just configured TAA + Frame Generation. Excellent result. I must update that previously I had to use V-Sync, but I noticed that the stutter continued after a while and I realized that it was all because of an excel file with a macro that runs every minute. It was on my same CPU and after a while it caused tremendous stutters.

I have already removed her from here and now things are very smooth. Anyway. now without Vsync, without limits of FPS, TAA, FG, everything in Ultra.

 

NOTE: By the way, did you see the problem of the cables of the 4090 that supposedly catch fire? Be careful with that, it seems that it can be from breaking the cable too much from the connector.

You mean Jayz video? I started to watch it last night but feel asleep at some stage. Ok, so not too much strain on the cable. Have a fire extinguisher nearby perhaps?
