Noel, I've referred to FG-artifacts both in this thread and elsewhere on this forum, going all the way back to autumn '22 when the RTX40-series launched. I also posted videos using FG in different scenarios.

Artifacts are an inherent side effect with FG due to AI-generated frames inserted in between native frames. It does not bother me much except when panning very fast, or when native FPS is low. 

I'm wondering if this flickering that you see is something else though. I think we're both on an eternal quest for the best image quality - however I find it strange that our perception differs so much on this topic. 

It would be easier to discuss this if you could either upload a video, or link to one somewhere on the internet. 

I tried to video capture but it's not working well it's all torn and messed up, the output.  With FG off it's fine the video capture.  Shadowplay.

I did turn off Gsync just now and it's worse!

That is so weird,

I can honestly say I have never seen a single artifact from the day I put my 4090 in.

What cards/motherboards are you running?

It has to be something else then Noel,

My TV is only GSYNC compatible, I think your display while smaller is much better quality. I get zero artifacts or major flickering as you describe, just a tiny GSYNC flicker every now and then but it really isn't noticeable on this TV and it is few and far between.

So weird, The only other thing I can think of is that your current CPU might be really struggling to keep up with the behemoth that is a 4090

This could very well be it, if what Noel is seeing is the much-discussed frame insertion related artifacts. Being CPU/mainthread-limited resulting in low native FPS and FG doesn’t have enough frames to render an artifact-free AI frame. 

To put it another way: the artifacts are always there, but are barely noticeable at high FPS and become more pronounced the lower FPS is. 

A lot of us that splurged on a 4090 was probably not aware of the Nvidia-recommendation of 60+ FPS. I wasn’t before spending crazy $$$…

I was seriously worried my 12700K would be a huge bottleneck but from what I have seen it performs fantastically. I probably wouldn't want anything less though with a 4090. I am now on my 2nd flight with fps locked at 86 and it is quite unbelievable how smooth it is, before I was at 97FPS and that was smooth (set automatically 3 below my 100Mhz refresh rate) but I am thinking the lower FTV has a lot to do with this.

I am quite surprised, I'll never need to upgrade my PC again 🤣

P.s it must be quite late on The Executor, Are you planning which planet to blow up next lol

To get complete rid of this problem you have to have 60fps natively before using FG, but then what's the point of using it with the flight simulator that doesn't need more than native 60fps to work optimally?

Most people look blindly at fps and seem to care less about image quality, hence the big hype with this technology, but for those of us who prioritize the best possible image quality, it's nothing to write home about.

I just discovered something today,

I was previously running FG on my GSYNC compatible 55 inch Sony X90K (100Hz)  @4K. FPS were automatically locked at 97 due to low latency being set to Ultra and VSYNC on in Nvidia Control Panel. Best I have ever seen the sim, Today I uninstalled After Burner & RTSS then installed the latest versions as I was curious to try locking FPS with RTSS again. I tried this last year when I got my 4090 and the micro stuttering was horrible when FPS were locked with RTSS. Today however is a completely different story, I was trying different settings and found that not touching anything in NVCP or the sim and simply locking the FPS to 86 in RTSS and turning Front Edge Sync on I have witnessed a level of smoothness I haven't seen before. It is bonkers smooth !!!

When I was running at 97 FPS the FTV graph in RTSS was fluctuating between 7ms & 9 ms, the sim was smooth but locking it to 86 FPS with RTSS the FTV is now between 11.4ms & 11.8ms. The difference in how the sim feels is amazing it is smooth on another level. The simple explanation is as Noel discovered the more consistent the FTV is the smoother the sim will be. The beauty is at 86 FPS my 4090 has been sitting around 65% and both flights I have done this afternoon were in the Fenix with plenty of FSLTL traffic and ultra settings in the sim with shadows at 6144 and a cruise TLOD of 300. 

I would be curious if anyone else can replicate this, there is no flickering or artifacts just a butter smooth experience.

Here is a couple of screenshots, Look at the FTV

That was exactly my experience with these settings as well, but unfortunately it only lasts for one flight, the next flight was a stuttering mess with flickering screens again.

So I tried your settings instead, unlocked with latency at ultra and v-sync in NVCP, and I will never look back, I'm done, my game has never worked better than with these settings, no stutter and flickering, and super smooth panning.

Thank you for sharing them 👍

Do you have Afterburner & RTSS latest versions? If so try try setting your FPS to 86 and turning front Edge Sync on, with a 100Hz refresh rate I am astounded. On my 3rd flight and it is still as smooth with a very consistent 11.5ms FTV

Yes I did, but it only worked for one flight, your settings have worked for about for 6 fights so far.

I even rebooted my PC after flight No2 just to see if it was repeatable and I am glad to say it was

I've been trying to convince Vader to annihilate Tatooine, but Vader refuses. It's almost like that no-good sand-filled hell-hole has some sentimental value for the dark lord... Probably something to do with that Force-voodoo-nonsense!

It is indeed getting late, although I have to remain on the Executor bridge whilst on a red-eye flight back to Coruscant...

Here is a screenshot at 97fps, the way I was running.

Look again at the FTV, it is 9.9ms but nowhere near as consistent as locked at 86fps

Wow, that’s quite the difference! I’ll give 86 a go when we arrive at Coruscant.

Looks great, but can you hold 86fps at the gate on airports as well, or in other words, everywhere in all situations? I think that's important to keep FTV consistent, I think 90 FG (45 native) fps are a good starting point, lower than that and the problems starts to show, just as same it does in native mode, with jerky panning etc.
