Awesome thank you for the follow up report and glad it helped at least someone and good to know FreeSync works as well!

Cheers

I second the thanks for reposting your thread.  My sim has never been smoother!

Try setting Passive Waiting to OFF if you haven't already.  I'm finding it does generate slightly better FTV despite the 15% increase in main thread core loading that happens.  But that is not manifesting in stuttering which I was concerned about, from getting to close to main thread limited (which you can address by lowering the frame lock a bit).

Interestingly, the FPS I need to set is also 33 to get the bar and pie charts in CapFrameX looking the same as yours.  I can run at 60fps with some stutters, but just shows where you really need to set it.  No longer do I get long pauses or stutters on final!

As you said, 33 FPS with consistent FTVs is very smooth indeed and not very different to the 60fps I can run at with stuttery performance.

Although it is a relatively old post taking into account SU15 and so on, it still worked for me. Even with good machines like mine (RTX 4090, i9 13900K) I had some freezing and few stutters, specially close to big airports like EGLL or KJFK with much traffic. I have optimized many things (AI traffic basically with AIG, FSLTL and FS traffic, updated Addons, VSYNC and limited FPS in msfs, AutoFPS, PL) and that all have contributed but this hint by @Noel is excellent. It caused to me the smoothest experience in msfs I have ever had. I think this advice can help many people to get a smooth experience. The possibility of switching it on and off is also very practical for the whole flight, activating it in dense areas. I set 120Hz in my monitor and limited RivaTuner (what a wonderfull tool!!) to 60FPS (FG). I have already had good experience with PL in the pst. I am trying to use it with AutoFPS to limit LOD in the approach. I would like to thank @Noel very much for sharing this knowledge, I appreciate it.

Thx

Thanks Ry glad you found the old thread!  Since upgrading my OS and hardware the only thing not working as well for me is I'm no longer able to incrementally change the frame rate lock on the fly whereas in Win10 that was possible w/ RTSS' scripting feature.  It matters for me because despite the 4090 I have I don't use frame generation so almost always can maintain a rate of 45fps which is good enough though wish I could get around the visual aberrations I get with FG.

I use FG with TAA and I dont get as far as I see any visual aberrations. I saw some ghost effects with DLSS but not with TAA, have you tried in TAA?. I am in Win11 but I have not tried this incremental frame rate lock. That could replace in a way AutoFPS, right? How is it defined the incrementaly change, if you have a link at hand please let me know, otherwise I will google about it, Thx

I don't know what to make of it Ry.  I posted at length about this and for reasons beyond me I seem to be one of the few who report this.  For me it's mostly looking out of a side window at tarmac, most kinds of tarmac, and in most but not all lighting:  it strobes/flickers and it's really a show stopper for me.  Have no clue why!  Others don't seem to have this!  Or...is it just that I'm more sensitive to this?  Also, glass cockpit text and lines look less than stable not sure how else to describe it.  Yes, TAA here as well as AMD Fidelity FX maxed to 200, and Render Scale at 150 and image quality is nothing short of fabulous!   I've turned AMD FFX to 100 or whatever its default is and RS back to 100 and this does not change the strobing/flickering.  I do wish I could use FG at a locked native rate of 35fps x2 70fps w/ but the aberrations aren't worth the addition 25 fps.  I feel the absolute best image quality, at least on my display, is only achieved w/ FG disabled.  And this does fit with how FG works, IOW it's in line with expectation because the intermediate generated frame is not exactly the same as a native frame would be comprised, is somewhat degraded.  I think that part is so good now it's probably irrelevant except for these graph anomalies I'm getting w/ FG.  I'm clueless as to why others don't get this!  I wish I could look at someone else's display, like yours.  My base rate is 45 which fortunately is pretty much good enough in terms of rate, panning, etc.  

Let me grab a screen shot of how to setup incremental frame rate lock which you can for example assign the + and - keys to increase or decrease by 1 frame with each keypress.  That part though doesn't seem to work in Win 11.  Try it and let me know maybe it's something in my Win 11 config that prevents these scripts from running.

Noel have you tried turning off bloom while in FG? That stops flickering on my systems.

Thanks @Noel for the indications about framerate increments, that can be very usefull.

Concerning the flickering issue with FG, I have not realized it in my case but I will have a more detailled look next time I simfly. In my case it is most of the time a compromise between good and bad things. I agree there are some showstoppers...I am not quite sure I understand the effect you mean. I think it might help if you put a video here and maybe someone can advice something.

Gook luck and BR

Thanks Ry I really explored it to the Nth some time ago and even posted video but the problem was the video capture did not capture what I see on my display, at least not to the degree I have it.   Since upgrading my hardware I really am in good shape with a locked rate minimum of 45 most of the time in complex planes and airports with maxed settings and on rare occasion down to 40fps.  So really I am quite satisfied though if there were no cost another 25fps would be a good thing--more importantly being able to set the native rate to 30 or 35 would be my most preferred asset from using FG.  It's certainly not all bad but I find myself wanting to stop and turn it off too often so just have become accustomed to off.  I do believe you lose at some level image quality/stability using FG even when one doesn't perceive more serious anomalies as I do with the strobing on tarmacs.  And then there's the issue of my 2nd display which I interact with constantly, so going back and forth between main screen w/ MSFS and other screen w/ Self Loading Cargo windows.  With FG on there is always a substantial judder when the focus goes back to the MSFS, and that does not happen when FG is off.

The flicker is a fixed-interval oscillation with any panning or motion of the tarmac under many lighting conditions.  So that means when panning or during taxiing etc.  Tarmac that is a mix of dark and light pixels is the worst I think.  I could put up with it and try to ignore it but I find that difficult to do and always end up turning it off.  Again, a solid smooth 45fps is quite decent as you know so not feeling too bad not being happy with FG.

Thank you Maurice yes, I have to no discernible effect.  Dialing back some of my sharpening (Render Scale 150, AMD FFX 20) helps some, but not enough.  I'm hoping some day a driver revision will address this.  I think it's possible but won't hold my breath 😉

In my case it is motion blur which I needed to set to anything but off, otherwise my screen showed flickering with Gsync compatible DELL S2722DGFA. Now with the new G3223, flickering is gone even with motion blur off.

I did try your exact settings and I also see the strobe effect on Tarmac

Sorry!

Are the settings you're used to also showing this?  I know I can dial back AMD FFX and RS and improve the issue but not quite enough I'm too spoiled by best image quality.  I don't think you can beat the image quality/stability of the settings I use, but that is with my eyes, and my particular display.

I'm still trying to dial in and get used to HDR and it is getting better.  Turns out indeed the HDR Tony slider is what affects the aura issue.  At 25% it's insignificant for aura yet still differentially brightens up the VC dash.  I'm having less unexpected neon overcooked now that I went back to the Calibration App and played w/ the saturation slider.   But...it seem the more I dial out issues the closer it gets to my default SDR config so my jury is still not quite there yet.

Not so much as I don't have my sharpness as high as you - I don't see much difference above 140.  I only tried your exact settings for feedback as you said you were the only one seeing the strobing effect 🙂
