The only thing I really get is the occasional flicker from my monitor, especially if I tab over to my second non gysnc monitor.  It used to flicker quite badly (the main MSFS monitor) when I tabbed out or the screen focused on the 2nd monitor.  But I think a recent SU along with new nvidia drivers fixed that.

In my experience the artifacts tend to happen when the actual FPS drops and the AI tries to generate the new frame...  if I have like 30+ actual fps, frame gen works very well.  But when I go lower (and I do haha - eye candy!!) I definitely get some flickers here and there.

I def get the 2nd screen issue but there is no way around that for FG users and I don't mind it though it's certainly a complete non-issue w/o FG.  My base native rate also when FG is on is 30 x 2 = 60.  Believe me, I would happily keep it there if it weren't for these artifacts.   And as said, sometimes it's fine but almost always it's not. And here is another oddity:  if I click on the 2nd screen all FG artifacts on the main screen disappear until I click back on the main screen, despite the frame rate dropping from 60 to around 44 or so.   In fact I've done this just to get away from the artifacts just kept on the 2nd screen as long as able before going back to click something in the cockpit.  This behavior should give a clue about something, the fact I can click screen two and the artifacts disappear.  Hopefully with this post someone might have a clue where to look.

I only ever really get artifacts on the BKSQ Bonanza on the small window on the pilot's side. I see them largely the same anyway when I click away from MSFS (second screen) and the FG stops.

I've also seen some strange pixelation in the clouds (high or ultra) now and then, but can't imagine that's tied to FG. It seemed to start in the last month or two, so now there I think about it, it could be driver related...

Is it possible it's just a bad 4090?

I've known a few people with screwed up 4090s now.

Or is there a firmware update for it?

I've been perplexed at why it is I seem to be one of very few who find artifacts associated with hardware based Nvidia DLSS Frame Generation

Noel,

1. What is your monitor's default frame rate (i.e. 60Hz, 120Hz etc).

2. What framerate are you locking the sim too and how are you locking it? (i.e. Nvidia Control Panel, RTSS etc)

3. Are you using V-Sync and/or G-Sync?

I've seen some artifacts when using FG, but the most noticeable ones I've seen happen while I'm planning the flight and in the loading screens (when Alt+Tabbing mostly). While flying I've seen some in the engines when they are starting or when looking around (not many though). They never annoyed to the point I would turn it off.

OMG!  I am a little hesitant to celebrate because I had this happen once before, one of those rare times when the artifacts described are must less intense.  But...I realized when I put RTX4090 into the box I failed to change a setting in MSFS that I had been using forever:  AMD FidelityFX Sharpening.  I had it set on 200!  I set it to 0, and voila, much improved artifacts!  Not outright gone, but I can now honestly vote in this survey option #1:  Yes, I experience some artifacts but never find them bad enough to avoid using FG outright.

Sorry to drag others into this I just failed to realize it could be an issue because it wasn't with the 3080Ti for the past years and it really was not on my radar, obviously.

Anyway, having a lovely fly from EHAM > LFLL and enjoying the solid 60fps and nary an artifact the entire flight, including in the glass cockpit and FMC.   It is now very close to native.  As a side note I installed DLSS 3.7 but that had no effect on artifacts.

The only thing that I can think of is that FG is disabled whenever MSFS is not in focus. Not sure if that’s the case in your scenario though.

Wow, I really hope it stays that way as you’ve had your share of these annoying issues. Fingers crossed.

Btw I’ve always had the sharpening slider on 100. And I voted option #1.

120Hz, native 30fps x 2 = 60fpsFG, RTSS front edge sync, G-Sync

I had it at 100 which I think is default then moved it to 200 a good while back as I thought it made image quality sharper and never gave it a 2nd thought.  I tried it on and off a couple of times in a couple of scenarios today and clearly 200 make these artifacts worsen.  Maybe 100 is okay I will check.  I just restarted MSFS and did a quick acid test at KDEN aiming east shortly after sunrise in clear skies in the PMDG 738 and see if it's still good:  pretty good flicker out the side but better than w/ AMD FidelityFX at 200!  That type of lighting brings it out the most but easy enough to make anything else active and the flicker disappears.  For example I can click on my 2nd screen, or any app that can steal the show in front of MSFS will stop the flicker and it's softened enough to where only the worst lighting brings it out, and the glass cockpit and FMC are solid now.  It is very nice to put the base rate all the way down to 30 this really gives some headroom and it shows in terms of freedom from even rare stutters.  And CPU temps stays nice as well.

Cheers

Noel, just an offer of help...

If you don't already have V-Sync ON in your Nvidia Control Panel Global Settings (or your Nvidia 'FlightSimulator.exe' profile), it should be on when using a G-Sync monitor, and OFF in MSFS. There's a lot of great advice in here on how to correctly set up NVCP and MSFS (Reflex).

I use the FG mod, but I can confirm this happens whenever MSFS loses focus.

Wow, I gotta give it a try tonight. Did you finally leave it at 0 or 100?

I left it at zero.  It's certainly made the artifacts I tried to describe improve to the point I can live with them now.

Honestly, I don't really see anything unusual, maybe there is some minor that hasn't caught my attention, I use TAA with FG + AMD FidelityFX at 50, G-Sync + V-Sync on in NVCP.

By the time you get AMD FX down to 50 most all of this aberration disappears which is why I've been able to complete two flights now w/o getting nasty artifacts.   As you know when you turn AMD FX off outright you definitely lose some image quality, so 50 makes sense as a compromise.   I became duly spoiled by having AMD FX at 200 enhanced further by render scale at 150 that combination really delivers clarity.  So for me whenever I can easily manage to maintain a native rate of 40fps from gate to gate which is the vast majority of the time I'll just continue leaving FG off because there is no downside with leaving AMD FX at 200 when you aren't using FG.  For flights that are so demanding no can keep the rate at 40 I will switch to FG on and dial back AMD FX to 50 or 100 as able.  We're in a space where compromise is still the order of the day but the choices between options are all quite good!

Does AMD FX still come into play if you use DLSS > DLAA?
