ASN introducing major stuttering in P3D 2.5

Recommended Posts

Hi.

 

I've noticed now on several flights that P3D is stuttering quite a lot, in mid flight/cruise and especially on descent. If I quit ASN, problem goes away and everything is smooth like butter. Open ASN again, clouds load in - instant stutter fest.

 

Anyone else experienced this? Any way around it? I'm using the latest ASN patch as well. Its a shame becuase it occurs with minor cloud density...

This occurs with me as well. Although I was using REX weather for a while and it was telling that it was the cause of stutters. When the dialog text started the injection stutters occurred. Same with ASN, although the problem subsided when I changed RAM and CPU. Still noticable tho.

I have ASN SP2 and not had any issues running it in P3D v2.5. Rock steady.

I have not experienced this.  I do not use any tweaks and my settings in P3D are conservative.  I know if you turn up shadows and some other settings in P3D, ASN will need more resources to work properly.  Isn't stuttering caused by high settings and, when you add a program like ASN/REX that might use more resources, it might cause stuttering to occur?  You are no longer using the default.  You are using a commercial addon program which has improved the default.  Or, is ASN/REX supposed to be exactly like the default without any enhancements? Stuttering has been a major problem in FSX/P3D/FS9 and it will continue to be a major problem when everyone wants to turn up the eye-candy.

Very valid points there, Jim. I've only adjusted using the latest NickN's tips. Nothing more. No maxing-out as I know my hardware will not take it.So. I'm happy with my FPS and smoothness.

Hei der Brynjar,

 

ASN is incredibly resource hungry. When I tested it, I found that it was a major contributor to introducing stutters and slowing overall P3D performance.

 

I use FS Global Weather, it offers much more realistic weather, and does not come with the performance hit I experienced with ASN.

I'm running P3D 2.5 and ASN SP2 (haven't installed the latest update yet). Silky smooth locked 35 fps with no stuttering in the Aerosoft Airbus X at LatinVFR's San Juan on my fairly modest system.

The only time I noticed ASN causing stuttering is when it updates the weather. And it's a very minor stutter that takes about 1 second. Have you changed the setting that increases the range of the clouds and weather updates? ASN might be trying to get more METAR/weather reports, causing more stuttering.

Thanks for the reply, Jim. Yes, I am fully aware that high settings will of course bring a system down on it knees. My settings are, like yours, very conservative. Only a few must-have tweaks in the CFG (e.g OPTIMIZE_PARTS). 

 

LOD radius 3.5

NO cloud shadows

All autogen density set to sparse

TML 1024 including REX clouds

Cloud density set to medium within P3D

In ASN, all settings are mostly set to default, except lowered cloud distance

 

So you see, its not my settings which are causing the issue. They are pretty much nerfed all the way down to save VAS and FPS. Might be placebo, but I felt I had much better performance with ASN on previous versions.

 

If anyone on to try a scenario, load up EHAM airport today with weather from around 14-16.00 AM (UTC timezone). It should be raining, low level clouds, 5000m sight.

 

METAR: EHAM 031425Z 17013KT 4600 -DZRA FEW004 SCT006 BKN007 15/15 Q0999 BECMG 6000 SCT007 BKN012

 

On ground, there's almost no stutters. The problem starts to appear in air and above clouds. Well that and draining 20 FPS from my system.

I have no such issues. If this is happening to you, there is another issue - I suggest contacting support.hifitechinc.com and opening a ticket. They'll get you sorted out quickly.

Hi,
 
When you turn off ASN, the weather theme also goes away which is probably why you're not seeing any stuttering. I've been using ASN since v2.4 and can't recall ever seeing stutters due to ASN consuming large amounts of resources. Have you tried uninstalling ASN and re-installing to see if the issue persists?
 
Are you using Sparsegrid Supersampling through Nvidia Inspector at all? If you are, this is known to cause performance impacts when in cloudy conditions so try changing that setting to see if your stutters go away.
 
A couple of setting changes you can make in ASN to see if the stuttering reduces is to uncheck the "Force BKN to 7/8ths" and uncheck the "Enhanced overcast conditions".
 
If ASN was truly causing stuttering you would see it every time it's enabled and not just in certain situations (The problem starts to appear in air and above clouds).

No stutters here with ASN , but I am using it over a network...

If you a spare pc or laptop you could try it too.

Just completed a flight 10 min ago in the NGX with ASN from Edinborough to East Midlands. The weather was awfull with some major storms on approach to East midlands. Basically, very heavy weather and poor visibility. The sim performed perfectly but the ride was very bumpy.

 

I have ASN running on the same PC as P3D and was downloading the freeware mesh at the same time. I live out in the wilds of Wales so my internet speed is slow but non of this contributed to any issues

 

i use 512x512 HDR clouds which even when spread across three screens give perfectly good visuals and great performance. Also check that your not using SGSS as mentioned above.

Not using any NI settings, including SGSS. Only AA is set within P3D.

 

I've narrowed it down to something else now. When looking at, or flying above/towards a very uniform low-level layer of clouds, stutters and huge drop in FPS occurs. If I close ASN and restart, problem is still there but to a less degree. Maybe I should try FS real weather just for fun.

ASN just hangs out doing nothing until ASN refreshes the weather. Change the ASN weather refresh rate to something long like 60 minutes and see if you still get periodic stutters at short intervals. If so, it's not ASN, but rather the sim that is having trouble coping with the injected weather at the chosen sim settings and ASN settings.

 

There is also an ASN option under Simulator depiction settings called "Suppress local weather changes". This also may help with periodic stuttering.

Hi! Do you use Aivlasoft EFB on your flights? That program (unfortunately, I really like it) caused very serious stuttering for me.

That is definitely not one of them.  Did you read the Optimize_Parts topic.  It started out with yes, a must have and then things went downhill from there.  If it was such a good tweak, do you not think that LM would have enabled the parameter by default?.  They want a smooth operating sim too and right out of the box.

Those settings are awfully low and should not be causing you any problems.  Mine are much, much higher.  There are many guides here in this forum and in the Tips and Tweaks forum that might help you.

 

I think I will write an AVSIM P3D Configuration Guide based on guidance here in the P3D Forums and those over at LM.

I use it all the time in conjunction with ASN, and have yet to suffer stutters.

I use EFB also with no issues.

Jim, I followed NickN's tip on this and amended it to =1 but have not had any issue with it.

I don't understand your statement. You say you've narrowed it down to something else yet appears you're still pointing the finger at ASN. I'm confused!? Huge drop in frames associated with clouds isn't an issue with ASN, it's an issue with the clouds. Have you ever changed the following line in your cloud.fx file - GetScreenQuadPositions( quad, width*0.5, height*0.5 ); to something other than the default value of 0.5? Open the Cloud.fx file in notepad and search for "GetScreenQuadPositions" and tell us what the values are in your file.

I fighted a stuttering issue not long ago and in my case it went away when I stopped using EFB. As someone else said I too like the application a lot but must say how smooth my simulator got after I stopped using EFB I have never seen before.

 

Still though I'm not sure if it's 100% fair to blame EFB, it might also be SimConnect being flooded by different add-ons that heavily rely on SimConnect. Both EFB and ASN are two such add-ons.

 

As for the OptimizeParts tweak there was a good explanation made by LM what exactly this tweak does, why people are seeing different results using it and why it's not enabled by default. In short IIRC it's most about what aircraft you're flying and how that aircraft was built/developed. With some aircraft you will see great benefits having the tweak enabled and with other aircraft it might even decrease the performance. I'm doing all my flying in the NGX and in my case having the tweak enabled has given me some 8-10 extra FPS and zero issues so wouldn't run P3D without it.

 

As for clouds (and other textures as well for that matter) I never use any higher than 1024. To me the visual difference is close to none vs 2048 not to mention 4096 (maybe with the exception of some very detailed airport scenery add-ons) and this gives me both a more smooth sim as well as helping me save some highly valuable VAS. Since day one with P3Dv2 I'm using the free HDEv2 clouds and I'm very happy with them!
