Guess what ? I am almost 100% sure that my stutters cause was GSX… I tested pushing back with and without it and the difference in terms of smoothness is significant… I know there is an open thread on this issue on the FSDT forum…

OK... I have found my sweet spot... DSR 1.75, DLSS Ultra Quality, Vsync "Force On" in Nvidia Inspector.. some other settings "high Quality" on NI, of course DX12 and FG ON. The result is a stable and very smooth 60 fps, no shimmering at all...some minor stutter every now and then associated with panning or turning n the ground with lot of vatsim traffic at heavy airport, but nothing major...hopefully they might be mitigated by the improved memory management coming with SU15......honestly I have no idea what caused my previous issues and FPS drop....most likely a setting I had overlooked...now overall very enjoyable and immersive experience.. the only caveat is the GPU is always working around 95%-98%.... the workaround for this is to set the monitor refresh rate to 30... Vsync will then cap the frame at 30...same smoothness and no noticeable difference in Sim behaviour, but GPU loads reduce to 65% max (less frame to deliver). One extra info.... I disabled multithreading (or whatever is the AMD equivalent for this), and this seems to have had a slight positive impact. @Cpt_Piett Quite tempted to replace my 8 yrs old LG Ultrawide monitor with some HDR/GSync same size monitor.... 😀

I have tested different Vsync options with a FPS hard cap under all conditions and I didn't like the results...

Following the discussions above, would a Gsync monitor be a good option for MSFS ? I have conflicting reports... is it really a game changer ?

No, this is not what I do...let me clarify: I ALWAYS use Vsync, because it is the only way to avoid screen tearing unless you have a G Sync monitor or similar, which is not my case. To put it simple the Vsync avoids screen tearing by synchronizing the rendered frames with the monitor refresh rate... so in a 60hz monitor the Vsync will ideally sync the frames at 60 fps, provided that the system is capable of delivering 60 fps. If the actual fps are higher than 60 then the Vsync will cap fps at 60 (there is no need to use a hard cap at 60 fps in this case), but if they are lower, there is no way they can be syncd at 60, and in that case the Vsync will anyway continue to avoid tearing but stutters may occur depending on how large the gap between the Sim fps and the monitor refresh rate is. Here is the benefit of the "1/2 Refresh rate Vsync": it syncs the frame with half of the monitor refresh rate, so in a 60 hz monitor, if the system is able to deliver at least 30 fps, then the result will be a perfectly smooth, stutter free 30 fps rendering. What happens in my case is that even if I select "1/2 refresh rate Vsync" in NVCP, whenever I increase the monitor native resolution using DSR either 2.25 or 1.75, the "1/2 refresh rate" feature doesn't work, and Vsync continues to work as a standard Vsync, that is trying to sync at 60 fps, and in heavy scenarios, my system is not always able to provide stable 60 fps, and here is where the stutters come from, at least this is my conclusion.... for the time being... however, it is good to know that with my same hardware and my same MSFS settings you don't have this issue...in the end, I have built my rig just very recently, so maybe I still need to fine tune some settings...

Thanks for the advice… will try it as soon as I will be back in front if my Sim PC, that is after Easter…☹️ I am not on Beta either..

Actually this is strange and I am struggling to understand the rationale of what happens: at upscaled resolutions the 1/2 refresh rate Vsync doesn’ t work, that is even if I select it in Nvidia Insoector I only have the full vsync active which caps the FPS to the 60 native monitor resolution… but if I lower the monitor refresh rate to 30 then the 1/2 refresh rate kicks in and caps the frame at 30…have no idea why this happens.. and the other interesting thing (maybe that’ s obvious) I have found is that once the frames are capped the consequence is that the GPU load drops significantly (most likely because less frames needs to be rendered)… from 95% to 60% roughly.. in both cases I have Frame Generation ON, and it works, not doubling the frames of course, but giving that extra boost which allows me to keep 30 Frames… with FG OFF the performance decay is noticeable.. one curious thing happened today: at Inibuilds EGLL, departing from Terminal 5 with all the T5 stands busy with Vatsim traffic (FSTL aircraft), with DLDSR @1.75 and DLSS quality, normal Vsync (not 1/2 rr), I had stable 55-57 fps at all time from flight preparation, to push back, taxi and take off, with almost no stutter whatsover.. the only difference vs previous flights was that I didn’ t use GSX…. Didn’ t have the time for another test, but that’s an interesting clue… more to come with further tests.. cheers ezio

No...no G Sync monitor...in the plans for the future, but not at the moment...

Great discussion here and a great contribution to a better and better sim experience.... I just want to share my recent experience. I have a Ryzen 7800X3D paired with an Asus RTX4090 and a 21:9 Ultrawide 3440x1440 60hz monitor.. I have tested the DLDSR 2.25x option + DLSS Quality.... vs just DLSS Ultra Quality.... Frame generation enabled in both cases... nvngx_dlssg and nvngx_dlss updated to 3.6 version.. all MSFS settings to Ultra and TLOD/OLOD 150.....no question about the performance in terms of FPS...in both cases the FPS and Image quality are great, but.... I need to enable Vsync (through Nvidia Inspector) to avoid screen tearing (and doing so I have my FPS capped to 60), and every time the FPS drop below 60, even just around 56 or so, I have got heavy stuttering... this is particularly occurring in cases such as Inibuilds EGLL, with Vatsim traffic, using Fenix, where I have fps ranging from 45 to 57.. the only way to have a perfectly smooth sim also in those conditions is to set my monitor refresh rate to 30hz and use Adaptive Vsync 1/2 refresh rate...this caps the FPS to 30 and everything is perfectly smooth even in the heaviest conditions, and visually stunning. I know that most people will scream that it is meaningless to have such hardware to run at 30 fps, but whoever has experienced this has realized that 30 FPS smooth, and I repeat again "smooth", is the sweet spot for heavy addon scenarios and aircraft in MSFS. Having said that, I have made three flights in the last few days, one with just DLSS Ultra Quality, and two with DLDSR 2.25 + DLSS Quality, and while the first one was successful, both the ones with DLDSR, although giving a slightly better visual quality, ended up with a screen freeze and a video driver error message. So to summarise my experience so far: DLSS Ultra Quality great performance and visuals..... DLDSR+DLSS Quality similar performance, with slightly better visuals but still some fine tuning to be done to avoid issues... I will need to build up a more significant number of test flights. Ezio

Hi, glad to read this as I am just about to move from my I9-9900k to a system very similar to your one with a 7800x3d. Just a couple of questions: 1) are you using the stock frequency and default bios settings for the CPU or are you using any kind of overclocking ? 2) I have always used Intel CPUs, where I had a “turbo boost” option in the bios to increase the CPU clock (not the manual overclocking, but just the turbo frequency boost which needed to be enabled in the bios to have the CPU max clock increase), but with the 7800 my understanding is that the increase from the base 4.4 Ghz clock to the boost 5.0 Ghz is enabled by default… is my understanding correct ? thanks and enjoy your new rig..😊..! ezio

Does it work also on RTX 2080 series ?

Great video and thanks for sharing. As everyone else here I am looking forward the release of GSX. just one question, either for you or for Umberto: on the Fenix you start the progressive refuelling via the Fenix EFB load page clicking the Load Aircraft button. However in the Fenix this button triggers also the passengers boarding and cargo load.. how do you handle this ? Board passengers and load cargo via GSX first and then refuel using GSX triggered by aircraft EFB button ? If so, does GSX knows the right payload for the flight ? thanks ezio

What about the integration with addon aircraft that have their own refueling system such as Fenix or FBW. Will we see some sort of coordination/integration with GSX ? If not now are there plans for future development ? thanks ezio

I am on SU10 Beta and my results with DX12 are weird… in some airports I have great performance, stutter free, while in other airports the Sim is unflyable…just a slideshow….I don’ t have the same difference using DX11… actually I don’ t have any performance difference at all among all the addon airports I have…I am using a 2080 Super…latest drivers installed…. I must be missing something…. I am not using DLSS as I don’ t have the option showing in MSFS menu, but that’ s another story… Ezio

I used to, but I have removed after I read that it caused conflicts with the Fenix

So far, since I have installed the Fenix, I haven't been able to complete a single flight.... 3 issues in a row: 1st flight, PC hangs after 1 hr of flight, 2nd flight CTD after 40 minutes, 3rd flight all cockpit switches and knobs unresponsive during descent, 1.5 hrs after departure. Fenix APP has always been kept open. Further to this sometimes I have had MSFS freezing during loading the flight (this occurred only using Fenix), anticipated by a cracking sound in the MSFS music theme, so I had to "kill" the Program via task manager and restart everything. My MSFS settings are mostly "HIGH" and I am able to have very good performance on Fenix, very smooth and the airplane is an absolute beauty and once this issue are sorted it will be a game changer in MSFS but for the moment, at least for me, it is unusable due to the impossibility of completing a flight. So far I have accumulated about 40 hrs with FBW Airbus with no issues at all... this is not obviously intended to be a comparison between the two products but just an indication that my rig and my MSFS set up are working quite well, and up to now I have not had any issue at all with MSFS. My PC secs are in the signature... regards Ezio

Bryan, it looks like the newly released Fenix "doesn't like" any other pushback tool, other than the integrated one. Are you considering working on making PBE fully compatible with Fenix A320 ? That would be great..! Cheers Ezio

Thanks for the suggestion, but what is Ctrl-F10 supposed to do ?

Hi, I have created my set of custom cockpit views for the two aircraft that I mostly use, that are the default C172 and the FBW A320. Each view has then been bound to its own joystick button...everything works fine but I would like to eliminate the annoying zoom change which occurs when I press twice the button assigned to a certain view. In other words, if, for instance, I have selected the pilot view and I press again the button assigned to that view (which usually may be necessary to recenter the view point after a panning around), then the zoom level changes and I have to press once more the same button to restore the created view. Is there a way to avoid this zoom change ? Thanks Ezio

Hi Bryan, no, no other antivirus whatsoever apart from the default windows defender on which I have added the PBE folder and .exe in the list of exceptions. PBE.exe has been Run as Administrator since the very first run. This evening I will send you a support ticket Ciao Ezio

No chance....Firewall completely disabled...every time I Run it, it returns with a request of activation as if it were the first time. Next step I will try to remove and reinstall...apart from the main program, which files do I have to remove to completely delete any leftover of the current installation ? Thanks Ezio

Bryan, thanks for your reply but I have tried and it is not working... it still reinitialize every time I launch it. Ezio

Hi Bryan, just purchased PBE and everytime I launch it, either as standalone or via the MSFS toolbar it always requests me to input my data and validate the License. I usually run it in Admin Mode, as well as MSFS, but I have also tried to launch it non in Admin Mode, but the result has not changed. What am I doing wrong ? Thanks Ezio Cingolani

Good news....! yesterday I noticed that although I was using a perfectly working microphone, FS2Crew did not pick my voice (I activated the green bar to check it and no voice command was reported on screen). So this made me even more confident that there was some sort of conflict somewhere. Then I realised that beyond the standard Realtek audio drivers, there was also a Sonic Studio suite installed in the system and I remembered I read somewhere in the Manual that Sonic software had been reported by some users to have potential adverse impact on FS2Crew application. So I uninstalled it and now I have everything working well with no hangs or CTD on exit (okay, I only tested it twice, but at least now don't have hangs on exit and my voice is picked correctly). Cheers Ezio

Will do and report back.... thanks..!
