Pauses Finally Cured?

Hmm, now this is interesting as GSX has not until now, unless I'm mistaken, had the finger pointed at it. I wonder how many sufferers of these pauses have GSX installed... 

I don't have GSX yet get long pauses. How long has GSX been around as Rob posted about getting them back in 2015?

Ah, so much for that theory! 😒

I think it is related somehow to many different aspects but coming all together on one particular thing: the stutters appear as soon as the simulator is somehow flooded/overwhelmed with calls for whatever.

Yup, no one has been able to pinpoint what it is exactly..

It is not legitimate scenery loading activity, but rather some kind of re-indexing caused by what...?  :unsure:

I had my first "long pause" experience just a bit ago. It wasn't a mere 8 seconds, more like 15 or 20. I was convinced it was locked up. I do have a Lot of Orbx and SODE, but I've had all that for quite a while. The only thing I was doing out of the ordinary was running the GTN 750 and a GTN 650.

I have been testing with the default Mooney.. no GPS addons..

All I can say is that one's own particular experience may be dependent on the environment in which you operate: in my case with Orbx LC scenery loaded and the FSDT KJFK v2 scenery, the cause of the long pause on the approach was definitely GSX (not SODE) and now I can land anywhere with this combination of scenery with buttery smooth performance and no stutters or pauses whatsoever with GSX uninstalled. If you spare the time to isolate possible causes of such issues you may well identify something eventually, as I did. That said, I think this is not a particularly productive way forward governing the time spent eliminating such issues when one should be enjoying a professional product which you would hope and expect to be largely free of major hiccups. I do hope that the underlying causes of our problems are formally identified at some point and progress can be made in optimising code by developers to prevent the worst experiences from arising in the first place. But yes, I do agree that when major pauses are encountered this does detract from our enjoyment of the simulator and more particularly (and critically) when they occur in the landing phase. Where the latter is concerned, this is a serious issue which would undermine the integrity of the training environment for anyone who practices nailing their approaches for professional applications (as I am sure many real-world pilots do), although I do appreciate that the simulator (as I have found) is trouble-free out of the box and it is only when we saturate proceedings with our addons that problems may arise. If the nature of the beast (the freeze-up problem) is formally understood at some point then we might expect that developers could carry out the necessary modifications to eliminate such occurrences. In the meantime, I guess we shall have to suffer things as and when they arise and deal with them accordingly.

Yes the GTN is probably your issue.

You must use the GTN config app and for any aircraft with the GTN installed, set CPU use, to "ALL".

ANY other settings for me, causes stutters. I have an i7 7700k with HT enabled and AM of 244.

So, the GTN looks for unused threads and all is good.

But you have to set it for EVERY addon you have the GTN installed in.... why Flight1 cannot have a global setting is anyones guess !

I may be Bert... but it is a possible cause.

Just something for him to look at.... not a scientific treatise.

Assumptions fill in the gaps where knowledge is lacking.... at least that was the basis of the scientific method when I did my PhD !

Everyone's system is different and changes daily.... we all have to make assumptions about stuff when we don't know what's wrong.

Anyhow, stuttering caused me no end of problems until I realised it was down to the GTN being set on Auto.... which I had 'assumed' was the best (and most intuitively correct) setting. Moreover, my setup was identical to the OP's.

And, unlike most people's 'cures'.... the CPU issue with the GTN is reproducable - 100 percent  of the time - at least on my system, which again, is almost identical to the OP's.

Crikey Im not asking for votes just suggesting a possible cause of his stuttering. He can try it.... if it doesn't work, move on.

Trying the plane without the GTN..... may be a good start !

 

......But thanks for your input........

Erm.... yeah. Useful.

I am sure there are many ways to make P3D stutter and pause.. but the pauses that the OP was referencing and several of us have been discussing after V4.4. was released, are pauses that occur at specific locations, like KVNY R16R..

The fact that this particular pause happens on systems with no addon GPS installed, tells me that changing GTN settings are not the "cause"..

Just trying to keep the discussion "on topic".. Sorry :unsure:

FWIW, this is the first version where I've had noticeable pauses at varying areas. Varying types of pauses also, landed at KRNO and just before  nosewheel touched, a 3 second pause. Other areas sometimes two or three short pauses in a row - not the quick stutter steps we get occasionally, these are definite pauses.

Like others, can't pinpoint a cause yet. But it DOES seem directly related to 4.4 because I did not have them in 4.3.

Same here Vic. I've never had these hiccup-like stutters prior to 4.4. At first I thought they were related somehow to ASP4 weather injection, but the stutters occur infrequently and are almost random in timing.

I'm wondering if some of the new (and configurable) graphics settings, like SCENERY_DRAW_DISTANCE, and MAX_TEXTURE_REQUEST_DISTANCE might be pushing loading of nearby scenery out to places where we wouldn't have seen it before...e.g. at KRNO, is the pause related to ORBX KTVL scenery suddenly getting loaded, or at KVNY, is loading of distant KSMO or KBUR scenery causing pauses?

In v4.3 I definitely still see pauses when first approaching airports, particularly big complex add-on stuff, almost certainly due to loading of a large number of 3D objects and textures (airport and AI traffic) all at once around 10 nm out.  Maybe in 4.4 you're seeing an unintended consequence of moving the ranges at which those objects load out further (?).

I have an i9-9900K CPU overclocked, 16GB ram, 1070TI and 2x1TB Samsung NVMe SSD drives, and performance is rarely an issue on this PC.

 

Except in P3D....

 

I use UTL, ActiveSky, PMDG, QW787 and the ORBX terrain mesh etc...

I was getting awful stutters in the sim even with traffic turned down and running 1080 instead of the native 4K.   I played with many many settings, followed a lot of advice here but in the end two things fixed it

1) in P3D 4.4 I cleared out all tweaks and changes

2) I turned Hyperthreading off.

 

Boom.    Now sliders are up, traffic at 100% etc, where this setup should be.  It looks great, and using UTL or PSXseeconTraffic injected from my utility PC, it flies (no pun intended).

 

So really if you have a good PC with lots of cores, turning off HT was night and day for me.
