P3dv4 blurry laggy slow texture loading popping and stutters

Recommended Posts

I'm seeking some other suggestions on my issue i'm having with p3d..

I've tried pretty much all suggestions found on here for the dreaded stuttering and laggy loading of textures (lagging even with the lancair at 150 knots).

So far i've done the following to try to get closer to a baseline:

1.  tried various AM's.. 
2.  eliminated AM's
3.  reset prepar3d.cfg
4. lowered graphical sliders
5. reinstalled nvidia 1080 driver to default using a clean install of the driver
6.  this is on a clean windows 10 (creators update, latest updates) drive as well, or was a month ago
7.  tried locking frames via NI, setting NI to Fast sync, Setting p3d to vsync on and triple buffer.. tried lower frame limiter inside p3d (all no good), so for now still on vsync on, triple buffer, no frame limit in either place

The next level of testing i went back to a "clean" scenery.cfg with only the baseline items enabled in sceneryconfigeditor.. meaning i left all addons in my original install intact, but turned them off (i have many including a bunch of ftx).

What I found was that i'm mostly stutter free on a cleaner scenery.cfg.. i'm 80% sure something(s) causing the stutter addon wise though not confirmed yet.  I actually found that disabling the ftx library in scenery.cfg resulted in no stuttering on my one test.. so..

My latest test was to reinstall ftx addons.. i did openlc, ftx global, nca and sca. (i removed the orbx folder first)..

Stuttering is better, but if you do hard turns in even the lancair around a lightweight area like Pittsburgh, you get a hiccup here and there (maybe every 10 seconds) as the turn occurs.  

I still have some landscape slow loading though, but no worse than when i tested with a fully clean p3d install.. it still pops autogen and tiles here and there.

At this point the only things i have left to try are to maybe turn off my overclock (not sure if this can actually cause either of these issues or not.. anyone have any experience there?)..

And also to take my clean install and slowly increment things again, beyond what i've done on my dirty install with just a "clean" scenery.cfg.  In general it feels like my stuttering may be linked to scenery addons or maybe my overclock, more testing needed.

Thanks for any input

Each system is different (where have we heard THAT before?) - you are doing what is needed to determine the problem on your system. I'd continue what you are doing and systematically eliminate each scenery add on until you determine the cause.

If your CPU has HyperThreading enabled, just try to disable it. Mine made quite a difference.

First of all I would forget about all cfg tweaks. I never use them and never need them. They only cause havoc imho. Secondly: a little pause every now and then is normal, specially when turning. So are random textures loading around you and things popping up from time to time. It's all part of the ESP engine.

My super tweak is: don't look too closely at what is going wrong but simply look at what is going right. Enjoy the flight! If I pay close attention I can see things moving and loading and popping all the time but I chose to not pay close attention and let myself immerse in the wonderful world of P3D. Just now I finished a flight above FTX Norway in the A2A Comanche with rainy weather: it was totally awesome. At one moment I noticed some texture loading and popping but I mainly noticed it because I was looking for it. Whenever I focus on my instruments (flying with VOR only here) and enjoy the beauty of Norway I just don't notice any of the moving/loading/popping.

When I read your post and read things like 'a hiccup here and there' and 'pops autogen and tiles here and there' I think the problems lies in your focus on the wrong things. Stop tweaking and start to enjoy the flying.

Make sure you have at least 15% free space on a SSD and 25% on a harddisk.

Last week my fps went up/down + stutters. It appeared that after installing that 1 extra addon my P3D SSD had just 11% free space. After placing the addon on another SSD the problem was gone and the addon is working great...

Wow, interesting tip.. 15% really?  Thats about 150GB on a 1TB SSD.. mine in fact has around 30GB or so free.. could be one thing to check.

Yeah i'm familiar with days of the past with this texture loading issue.. but prior to fine tuning it once i stripped it down to only a few addons.. i was getting stutters that would happen every few seconds.. it was very visible.. and texture loading or rather lack of loading that left the whole area under the airplane looking like i was flying over bad astroturf :)  

Once i thinned it down to a few addons.. yes the stutters are mostly gone and yeah i should let it go at this and start working them back on one by one till i figure out what truly caused the massive issue.

I havent tested this angle just yet, but was planning on it, though i think with v3 i did for a similar issue with no real results.

My system is not that far off yours.  It's a store bought MSI Vortex 7700 3.6 GHZ with a 1060 3GB vid card and 8GB Ram.  I get very good performance untweaked, the only thing I don't use is autogen so that might explain my performance.  I have a sampling of AI, all other sliders maxed, and I achieve my locked 33fps all the time.  Unlocked fps can jump into the 70's.  I surmise if my setup works well, yours should too although you have a slightly lower cpu.  The best bet us to backup your .cfg file then delete it so P3D rebuilds it.  Don't tweak your vid card until you've tried P3d's settings.  I went with P3d's settings slid right and did not have to touch my vid card settings.  I get no stutters, no blurries, no issues at all.  When I bought my system at Fry's I told the salesperson I was buying it specifically for flightsimming.  He looked up the specs in some book and the system fell above the recommended specs.  My system was marketed as a gaming system, although it was not high end.  I just bought the tower and used my existing monitor and speakers from my old system.  Since I had a VGA monitor I bought a converter cable, looks great with my 1060 card.

Hope my specs give you hope, usually the culprit in performance is having AA set too high.  I use 4X instead of 8X and can hardly notice a difference.

are you running a 4k monitor??

I am in fact.. i should have mentioned that (i have also tried no AA, but it didnt make a difference, so i've left it at 4x).. i run it at the 4k60hz res  (its a sony 43" tv technically).

I should mention, though often doesnt matter.. that the fps counter (via fraps) shows a solid 60, maybe drops to 57 when the hiccup occurs.. in the case of my full blown install.. i might only average around 50-53 in this region with those massive hiccups and blurs.

Have you tried locking the frames to 30 or 33.  I find I get more stutters and textures not keeping up more when I use unlimited frames or lock them at a rate the sim cannot maintain 100% of the time.  Note, my experience is based on Prepar3d v2 still, as I have not yet upgraded, but the same principle may still apply.

Yeah i had tried that, no real luck (either internal or external frame lock)

At this point i also tried turning off the overclock on my ram and cpu.. no change..

I also went to my clean OS i have on hand.. tried running the same addons via the same full blown folder (copied over my appdata folder and program data etc).. less stutters, slightly..

The real ticket still seams to be the FTXAA_ORBXLIBS entry in the scenery.cfg.. if i disable that its really ok, for the most part (i think).. i cant find any data online about this causing an issue which is strange.

The other thing related to blurries and texture loading.. i would think that they wouldnt do this close range to the aircraft for photoscenery, because i have that issue there as well (worse in some cases).

Sounds like a complete wipe of P3D and clean all remnants out is in order. Sux but sometimes there is no other option.

My latest test:

Installed from scratch just some of the orbx.. this time i left out FTXG (used a clean install folder of p3d and referenced all my addons that already exist elsewhere via scenery.cfg).. i only installed the libraries and openlc NA.

With this and very few of the many other addons active.. i had barely any stutter.. dare i say none.

I then turned on every addon (still just openlc for orbx though).. stuttering was everywhere every few seconds or so.. very laggy textures.

I did find if i set the p3d frame rate limiter to 33, i could stop texture loading, but then again many textures that hadnt loaded stayed blurry.. so one thing sorta cured another got worse.  Stutters were still bad, real bad.

So at this point i guess its either a series of addons i have causing the issue, even though i'm not flying in an area where they are active.. or.. left this out before.. i'm using symbolic links for parts of my addon folders.. linked to another drive.. again those areas arent active in this scenario but i have them enabled.. curious if anyone's ran into stuttering simply because of symbolic links being used to point to folders on other drives? (it works well with xp11 tho).  It might have also been FTX Global related and texture loading is worse with OpenLC NA (and ftxg) or just openlc alone.

Also if i turn on the photo real (megascenery earth) i still get pretty laggy loading close up tiles.

To save me going back to the first page,  remind me again what CPU and gfx card you have please.  I'm going through the same issue after buying a 4K monitor.

Can you run the monitor at 30 hertz??  

It's my understanding (and I could be wrong) that your CPU is going to have to work alot harder when you have 4K hence causing the blurries and stutters.   From doing a search last week it seems to be a common issue.

Have a look at these. Maybe they can help

With 3% free space your system is choking and will never run properly !

Look in MyComputer at that drive . It must be with red characters.

This is your problem...

I doubt it is the FTX library. Do you have the beta 64bit Objectflow2 activated? This dll file can cause stutters on some systems but they are going to solve it.

I don't think this is the case.  I am running a 55' 4K Samsung TV which I specifically bought for flightsimming and I'm running a 4770K @ 4.2Ghz.  Not only is it the best display I have ever had, but the performance is akin to anything I've had on smaller 1080 displays. I'm also running an Asus 1080 Ti graphics card

I can run my settings in-sim fairly mid to high with pleasing results.

 

But - as Jeroen said earlier, you need to look passed the little blips and stutters and occasional laggy load.  It doesn't happen often, but it can, and it will.  Thankfully, I've managed to get a grip on that flightsim OCD like trait.  Overall everything is much, much better than it ever was.

youve also got a 4770k and a 1080ti ... of course youve not got any issues!!!

ive got a 3770k and a 980ti and I get blurries and stutters using 4k

I have a friend who has this same issue - the common denominator is that he uses FTX Global.  When he uninstalled that it went away

I did that last nite.. took a clean install and only installed openlc.. no real change.

I'd recommend:

1.  Find a way to run your monitor at 30Hz (1/2 refresh option in NI if not supported native by your monitor)

2.  Don't install any Orbx Regions (as nice as they look, some Orbx Regions can cause long frames), stick with just FTX Global, OpenLC, Vector (limit active options).  If you've already installed Orbx NorCal and SoCal, uninstall via FTX Central and then uninstall FTX Global, OpenLC, Vector ... now re-install FTX Global and test, then re-install OpenLC and test, and re-install Vector and test.  Don't get me wrong, I love Orbx Regions, but they seem to cause problems in P3D V4 and I don't "think" Orbx re-compiled their regions BGLs (nor FTX Global or OpenLC for that matter) using the P3D V4 SDK (I could be wrong so don't quote me).

3.  The items that impact FPS (beyond add-ons) is SSAA, DL, DR, Shadows, SpeedTrees (Dynamic Trees)

4.  Check your DLL.XML And EXE.XML files (both sets) and see if anything is being loaded that could cause an issue (disable for testing purposes)

5.  Make sure you have the latest nVidia drivers installed 385.41 (clean installation) ... only issue I've noted with 385.41 is that ShadowPlay (video recording) introduces more long frames that aren't in my actual flight experience.  Note: with Add-ons there will always be some level of long frames (stutters) but they should NOT be so frequent that they become distracting.

6.  Delete your shaders folder in case it's corrupted (can happen when/if you CTD or Blue screen or lockup)

7.  Affinity Mask is another item to experiment with, for high core count CPUs, HT OFF seems to work well for me

8.  If OC, make sure you aren't triggering any thermal throttling (HWInfo64 will show you that info here: https://www.hwinfo.com/download.php)

9.  Turn OFF AI/Road/Boat traffic

But first step is to get your monitor working at 30Hz or 1/2 refresh, it will be extremely difficult to sustain 60 FPS/60Hz with add-ons installed and high (ish) graphics settings.

Cheers, Rob.
