  1. 1. Do you observe late autogen loading in patches while flying?

    • yes, in any case
      44
    • yes, but only with fast airplanes
      18
    • yes, but only with specific settings (plz. indicate)
      7
    • no, never observed this
      9
    • no, not anymore (plz. indicate possible fix)

Hi all,

As I am involved into the discussion about "autogen loading late and in patches" in the official LM Forums, I really wondered if this is something limited to some systems only (due to whatever reason) or if this is really an intrinsic bug of P3Dv4.x that simply not everybody is aware of (which I can hardly believe...). That's why I created this poll, I am simply interested in the current situation.

So, plz. participate in the poll :-) If you do not observe this autogen loading in patches, it would be nice if you post your autogen settings and whether or not you use limited FPS, HT, AF, FFTF. Thanks for your efforts,

Regards

Limited fps 30

HT OFF

AF 16x

FFTF 0.18

 

Works pretty well for me, I only see very occasional popping of scenery , in heavy autogen areas, or in a fast jet.

its finding the right balance of locked fps vs FFTF.

No bug.

When i attach an trailer with 1 ton on my Mercedes and the car has less speed-up performance it's also not an engine problem.

Might be, then I did not yet find the correct combination. May I ask what settings you use for autogen draw distance and autogen density (buildings and Vegetation)?

This comparison is... well, no comment. Does it help if I make the following statement: is it then an engine problem (=bug) if the precedessor of this mercedes with exactly the same engine, same amount of horsepower etc. was capable of accelerating faster and had less issues?

Sorry, but no. I can turn everything down to the minimum and the issue still persists. And it is amplified if you reload several times the same scenario in a row. Means: there must be something wrong with the unloading of autogen that is not used anymore vs. the size of the autogen buffer.

I use the dynamic FFTF tool so its not really and issue any more

Could you elaborate this a little further? I do not see a direct link between FFTF and autogen loading late and in patches... You had this late autogen loading but with the dynamic FFTF tool it is gone?

I thought I read somewhere in a post by "Rob" that LM is aware of loading patches in the distance and they are looking for solutions?

This is an issue for me and it has very little to do with my settings or plane I fly. If there was a way for me to fix this by tweaking or changing settings, I would have found a solution a long time ago.

Good luck!

Its not perfect, but it does help. If you watch the below vid it will explain how fixed fps limiter and FFTF work. Then just imagine using a tool that helps automatically change the value depending if you have enough "spare" fps to dedicate to autogen.

Hi Ankh, see this thread: 

it a good read/watch. 

 

Regarding my settings they are fully right, most of the time. At egll for example, I usually knock them back 1 or 2 notches, autogen density. Also would need to drop fps to 15 or 20.

Are you sure that this applies for v4.3? The video is from December 2017... And me and others observing this bug are almost sure that it is pronounced since 4.3. Thanks anyway, I will watch it for sure and see if I find a solution. As a matter of fact, I don't see that much difference in the performance with autogen draw distance on "medium" or on "high" or even "very high". That's why it is so hard to accept for me that it has anything to do with the performance of my rig...

I presume this is when you run in 60 hertz??

It's certainly a bug for those of us who have a pretty beefy machine and experience late loading AG and late loading photoscenery with very moderate slider settings.

Yes that is correct. My monitors only do 60hz with free sync range of 35-60 fps. So it’s stiil nice and smooth at 30fps without free sync and no visible tearing .

This! So many topics about this issue that i lost count, the only solution found for those who suffer this is to lock frames, no more no less.

And how many times do we (the ones suffering from this) have to explain again that this occurs with limited FPS? I see it, no matter if I use 28 (for TE Netherlands), 30 or 36 (my normal Setup) as a limit... You should not confuse it with blurries...

Hi AnkH,

    Are you using a setting for FFTF? or just default? 

If you have it set to 0.01 like is recommended, frankly all over the place, that could be the root of the problem.

OK many thanks, its that with VSync on or off?? 

Reason I ask is I use 4k at 30 hertz and the mouse lag is awful

Hi Tooting, that’s with vsync off and triple buffer is naturally off also.

I have it currently set to 0.15, the value 0.01 is another of those myths going around the forums over and over again. But you mention a valid point, the next flight I will try with no FFTF to see if things improve.

Happens to me when I set fps to limited (say 24 fps), too. Not worse not better, just the same as with my usual 30 Hz monitor frequency plus fps unlimited, VSync on and TB on in-game.

I tried numerous settings and combinations, but when I take off from KSFO and fly into KSJC, autogen loads in patches. This isn't in a supersonic jet but just in a wee little C172 flying at 3000 ft.

I found one and only one setting to get rid of patchy loading, and this is autogen draw distance at medium, at most. In this case autogen fades in continually as it should, but unfortunately at around the autogen radius we had during the 3.x versions. I tried numerous other settings like LOD, tessellation, texture resolution, which don't change the result, thus I don't think it's just "poor performance" of my machine.

And in my case, I observed this in 4.0 already and reported it to the LM forum with accompanying videos a year ago.

This can clearly only be observed at relatively low elevation over extended plains filled of autogen like the Silicon Valley, the LA basin etc. It's much less obvious or even missing in narrow valleys, areas void of extended cities etc. 

And yes, I own and use FFTF Dynamic which doesn't help with this specific issue in any way, at least not on my system.

Kind regards, Michael

Ok, now I did a flight with the AS CRJ from LSZH to EDDF (good test scenario for me as both Airports are heavy but the flight distance is short) using FFTF=0.33 (Default) and reasonable settings (autogen draw distance on "medium") and the late and patchy loading was reduced considerably. Anything above "medium" reintroduces the patchy and late loading again. So yes, it is somehow also related to FFTF, but above "medium", it seems bugged.

And of course, the FPS with FFTF on default were hardly acceptable during approach of EDDF (something around 16FPS...).

We have a similar hardware, Michael, so did you find any definitive benefit of FFTF Dynamic vs. just using FPS Unlimited, Vsync On and monitor's refresh @20, @25, @30?

AG is only loading in patches with high AG radius settings..
