...due to the fact that my 13600K was struggling so much on heavy airport addon sceneries such as EBBR, KJFK, KLAX and others. I was down to 30FPS, sometimes even below with AI traffic active and this ruined an otherwise great simming experience again and again. So I took the plunge with a reasonably priced 4080 to replace my 6900XT. I use a single monitor with 1440p resolution and mostly ultra settings, TLOD both at 200. 

Now, some weeks later, time to write a short resume: yes, frame generation is great for MSFS. It still produces some artefacts clearly visible, but I will take those everytime for the sake of getting at least 50FPS on big hubs now. Together with my G-sync compatible DELL S2721DGF, the sim could not be more smooth. However, I am surprisingly not 100% happy, how come? I would have never believed this, but the AMD card was actually performing better in several aspects in MSFS. Let me elaborate this a little bit for you. When I switched from a 1080Ti to the 6900XT, I was really interested, even wondering, how the AMD card will play along with P3Dv5 and MSFS. And guess what? I did not have to do anything to work perfectly. No driver tweaking, no color adjustments, nothing. Simply installed the card, the driver and off we went. Freesync did a wonderful job, nothing to be configured on this side neither. Just no frame generation in the AMD driver suite so far, also nothing on the horizon for at least half a year and no certainity, that it will be implemented into MSFS anyway. That is why I switched back to nVIDIA. 

And guess what? I was back to tuning and testing... G-sync on or off? Vsync on or off? Frame limiter in the NVCP yes or no? Ahead rendered frames setting? Color filters via GeForce Experience or via driver globally? Sharpen? And and and. NO chance to just install the 4080 and that's it, when I do this, I get very, very annoying screen flickering, I get strange washed out colours, sometimes stuttery experience. 

To be honest, this was some kind of a disappointment to me. Many people always criticise the AMD driver suite and over decades the common sense was that AMD cards are great, just not for the ESP based simulators like FS9, FSX and P3D (and Xplane). But my experience of the second newest AMD generation is 100% contrary. While I had absolutely nothing to be bothered with using the AMD, the switch to nVIDIA resulted (again) in a tuning fest. 

Now I am somehow settled, I found the best possible settings but they come at a cost. In my case it is this annoying screen flickering. Never thought of that to be honest, as my monitor is listed as G-sync compatible. Obviously a common issue. Sure, the frame generation is gold and turns the switch to nVIDIA still into a mostly positive experience, but still. My very subjective personal experience is: get and AMD card if you want to fire and forget about the settings. Get a nVIDIA card if you need the best numbers due to FG and you can live with a tuning fest.

How are your experience if you switched from AMD to nVIDIA (or vice versa)? I know that this story is prone to end in a "war" between AMD and nVIDIA word not allowed, but that is NOT the intention, I just wanted to share my experience which is contradictory to a so-called gold standard that established over the last decades regarding flight simulations. 

I am considering switching to a 4090 at next price drop, so thanks for sharing your experience. 

The first thing I would say is that you may be better switching to 4k resolution with that card.
I know it might seem counter-productive, but you may actually get better performance for reasons I can't go into as it is too long winded, but Gamers Nexus cover the subject quite well.

I take it you don't have a 4k monitor?  If so, obviously that would involve spending more money, but the 4k experience in MSFS is so much better than '2k', with the instruments and distant scenery pin sharp - much easier to pick out those runways in the far distance etc.

I don't know or understand what would be causing your flickering, but my guess it that it is monitor related, or something to do with the set up of it.

Performance is perfectly fine, it was just not "install the card, install the driver suite and off you go" as it was with the AMD card. The G-sync flickering on G-sync compatible monitors (even on G-sync native ones) is a problem widely spread and discussed, there is no definitive solution to this, except turning G-sync off for MSFS, which in turn results in stuttering and to resolve the stuttering, you have to again play around with NVCP settings. So, as it is not even 100% sure that a fully G-sync native screen (with whatever resolution) would solve this issue, I am certainly NOT going to spend another several hundred bucks. Especially because so far none of my other games I play regularly show the issue I have in MSFS... 

Do you have a link to the GN coverage of this 4K topic? Because: with todays drivers, you can easily activate super resolution and basically USE 4K even if the monitor does not natively support it. IF 4K alleviates anything, this might be something to consider nevertheless, simply running my sim in 4K.

Uneventful.

 

In my case I have just renewed total hardware, but about the GPU I think they are really overpriced being NVIDIA the leader, so I opted to make a top computer with a middle-class GPU (less overpriced now) and with the idea to jump to a better card in a short future with more options on the table (waiting for new models and consecutively lower prices).

So I said "bye bye" to NVIDIA an I got a 6750 XT which paired with top hardware in giving me a great experience in msfs getting 40-50 FPS in heavy airports FSTL ON, all in Ultra except for TLOD at 100 (which is a CPU killer and insignificant difference between 100 and 200).

In my case AMD is making a great job, and they are working in its own frame generation technology witch will be deployed with the FSR 3.0 in a few month from now and the difference with NVDIA is that it will be applied not only to the new GPUs but also to old series starting from RX 6000.

Conclusion: If possible get the best hardware (CPU and memory) and for the GPU there is "life" after NVIDIA (and in a few months more...). 

Cheers for everybody !

This is by far not yet confirmed. AMD said they consider it bringing it to the 6000 series, but nobody knows for sure and if a 6000 series is capable at all. Besides this, as mentioned, it MIGHT come in few months, but maybe later and even more important, nobody knows if it will be driver based or if it needs an actual implementation into the game. The latter is much more likely, meaning even if FSR 3.0 hits the market, it still needs to be implemented into MSFS, which for sure will take some time as well. Personally, I doubt we see FSR 3.0 anytime in 2023 in MSFS...

Hi Chris, 

Do you think AMD is going to stay stooped watching the NVDIA frame generation technology working perfectly ?

           ..... about msfs 2020 implementation asobo has included all AMD technologies in the simulator (AMD is an Asobo studio partner) ..... the release date of FSR 3.0 I do not know, and about driver's implementation etc. I even know less (all I have written about it, is what the pc web's are rumoring about).

But what I do really know now is what I am experiencing with an AMD card, and it is simply great, why it is going to became worst? or why it is not going to be better? ......

... anyway this is only my experience and a personal opinion ... just this ....

Cheers !

I also use a Nvidia 4080 card, and experience no flickering, no washed out colors, no stuttery.
I did increase all settings in fs 2020.

I did install the Gigabyte driver (mentioned in the manual), and did not play with Nvidia settings ("out of the box")
My screen resolution : 5120x1440 pixels.
I'm using one 4080 display port output - not the hdmi output !

...And Davinci Studio is also running / rendrering much faster .. but this is another subject.

Thanks, but I have no issues getting G-sync to run, my issue is that only with very specific settings, the g-sync related screen flickering can be minimized (not eliminated entierly, sadly). 

I too just recently moved to the MSI 4080.  Couldn’t be happier with the performance in 2D & also VR.  Smooth as silk.  Finally stutter free (well most places anyway).  
Didn’t have AMD prior, but I do appreciate the insight & comparison.

Have you try to use V-Sync + G-sync ? that's how I run the game with my G-Sync compatible monitor to get rid of the flicker.

I do, Vsync on fast in NVCP, on 100% in MSFS. This eliminates 95% of the flicker, still some occasional ones. And I also switched render ahead limit from 1 to let the 3D application decide inside NVCP.

Well, for me I had an AMD RX 6900 XT that performed decently for me in MSFS except that I had constant stuttering every time I would pan my view around either internally or externally. When I switched from the 6900 XT to an MSI RTX 4090, all those stutters disappeared and my overall performance increased dramatically along with increased settings. I have no stuttering and nice smooth performance in MSFS now. Further, I am running an LG 32inch G-Sync gaming display at 2k resolution, with MSFS upscaling set at 200. I do NOT use in game V-Sync, but have V-Sync in NCP turned ON to FAST. I do not experience any flickering or screen tearing at all. When I first got my 6900 XT I had an AMD system build (5800X3D). I then built a 13900k rig and put the 6900 XT in there. The stuttering issues I had existed in both builds with the 6900 XT. 

This has been my experience.

Are you using display port on your monitor?

Thant could be the key with G-Sync flickering. I wonder if a display port to HDMI cable would make any difference, I only get a tiny amount of flickering but it would be nice not to have it at all
