I've made two comparison videos of DLSS2 vs DLSS3. PMDG 737-700 ILS27L approach to iniBuild's EGLL starting from BNN. I decided to post the videos here since this thread is relevant to the 4090 and 12900K(F). Details in the video descriptions. 

As my brain seems to be intermittently on vacation nowadays, I just realized I had uploaded the DLSS2 video twice. I just started uploading the DLSS3 video but since it's 4K it'll take a while to process. 

First video: SU10 DLSS2.0

Second video: SU11 DLSS3

CapFrameX benchmarks

DLSS2

DLSS3

Note that while DLSS3 has twice the fps and decent x% low fps (0.2% low >30 fps), the frame consistency is worse than with DLSS2. This can be seen when comparing the second CapFrameX screenshots showing the variances tab.

I realize in hindsight I should have just captured both videos in SU11. Oh well. As this has been fairly time-consuming I don't think I'm up to the task of recording the DLSS2 video again. Should be good enough for assessing animation smoothness and stuttering though. As well as image distortions introduced by DLSS3 frame generation.

The differences: 

• in the DLSS2 video I used ReShade with a LumaSharpen shader among others. Hence, the image looks sharper. 
• in the DLSS2 video I used FSLTL with the injector, whereas in the DLSS3 video I used real-time online traffic with FSLTL base models

I recorded the flight using Flight Recorder. If anyone wants to do a comparison flight the recording can be found here. It would be very interesting to see comparisons with different CPUs. But then we should agree on some common settings - weather preset, time, vanilla MSFS. Well 100% vanilla won't work as I recorded the flight using the PMDG. But I'm happy to replay the recording and do another benchmark.

24 FPS on Arrival  and 35 FPS within the cockpit on cruising altitude with a I9-12900K and a 4090 ?
It seems something is not correct ..

Nope, it's correct. That's all I can squeeze out of my rig on ultra settings with iniBuild's EGLL and AI traffic. It's the same at iniBuild's KLAX, and at other major hubs. Of course I can turn down the settings and get higher fps. But the purpose of the comparison was to use the highest settings in the most demanding scenario. 

And perhaps it would've been better not to quote my whole post 🙂

perhaps also share the corresponding .FLT file to create identical environments/conditions?

Thank you for thoroughly testing.

Indeed major hubs are more taxing than small and medium sized airports. Add lots of AI + many clouds and you will see that it taxes the system a lot …. So

Good idea. Interesting weather around London today. Not sure how I do this but I'll give it a try. I guess it's from the world map?

@turbomax is it possible to save a flight while airborne? I guess I have to start from the runway somewhere then save at a certain point in the flight? 

EDIT: Just a bit too late to edit this into my original post. 

I've saved two .FLT files. The first one is with the 737 on runway 15 at EGBB ready to go. The second one is just before the initial approach from BNN. This is a couple of hours later than the second flight in the video, but the wind condition at Heathrow is similar (runways 27L/R in use). I hope I've configured everything correctly in the aircraft. The flight plan is EGBB/15 DTY2Y DTY DCT WCO EGLL/BNN.I27L.

Another edit: Seems like there's also these .SPB files that are saved at the same time. First one is here, second one here. I'm no expert with saving flights (in fact it's the first time I do it).

Will MSFS save the exact weather conditions in the .FLT file?

Would we have to turn off live weather?  Otherwise wouldn't the sim change the weather that's in your .flt file?

I have no idea to be honest. Hoping someone with some expertise on this can chime in.

Best thing setup with manual weather etc. so that everyone can use the same weather settings

Would it be possible to change to manual weather after loading the flight? Actually I've yet to try to load the flight as I just had a CTD in SU11, probably due to reshade.

yes, and can not be changed afterwards. try for yourself: save and re-load the FLT file.

Edited November 6, 20223 yr by turbomax

I think the second file (.SPB) is a PMDG panel state file. 

Selecting it in the FMC and the cockpit is exactly how it was when I saved it. Impressive. Most impressive indeed. 

Loading the first .FLT file and the aircraft loads at EGBB rwy 15. But for some reason I cannot access the toolbar menu. Hmm. 

EDIT: Couple of minutes into the flight and the toolbar menu appeared. Weather and time cannot be changed.

All this while Intel and AMD been playing games with our minds ($) by increasing the notch just a bit with the 'latest and greatest.'

that is expected behavior, so it can not be tampered with for training purposes I guess.

Well yes, but for this test we do not want the weather to change.
