More testing this time with a reinstalled ASN with the latest update. At first I thought I was on to something and then the dreaded stutters started to happen. Basically the same weather as the previous test with the same soft clouds tried both 32 bit and the DTX ver. ASN depicted the weather just about the same as opus but I could not get rid of the stuttering. I then shutdown ASN and just used the internal weather themes and you guessed it NO Stutters. So there you have it on my system at least. I guess its opus and soft clouds for me until the next ver od P3D or ASN which ever comes first!!

Hmm i never had any issues so i desided to increase layers from 5-7 and then the fps dropped dramatically. Back to 5 and no issues. Michael ups this was with FSX. Sorry

I had major FPS issues with ASN so I switched to Opus and I haven't encountered any drops. In fact, I get over 50fps even in overcast conditions.

I had this issue early on with P3D and ASN. What addressed the performance hit for me was to disable the enhanced overcast feature within ASN. 

 

A thought occurred to me when I posted this up. Given we're seeing slight stutters when ASN is running, I set the affinity for ASN to my last CPU core and also reduced the CPU priority from "Normal" to "Below Normal". I loaded up a flight out of KGEG and I didn't notice any pauses or stutters. Exited P3D, restarted ASN and P3D as usual (no affinity or CPU priority changes), loaded up my flight at KGEG and there were the slight stutters. Closed everything, rebooted, fired up ASN, changed the CPU affinity to my last CPU core and changed the CPU priority to Below Normal and I again didn't notice the slight stuttering.

 

I'm going to keep on playing around and I would be really interested to hear if the OP or anyone else running ASN and noticing these slight stutters in P3D could try this and report back.

That's what I have done in the past, but I have the luxury of having 12 physical cores (albeit their single thread speed is not state of the art and ~60% of an OCed 5960 Haswell E). Here's my start up P3d batch file, in case anyone is interested:

start /b "" /AFFINITY 0x400 "C:\Program Files (x86)\NaturalPoint\TrackIR5\TrackIR5.exe"
start /b "" /AFFINITY 0x200 "E:\Program Files (x86)\HiFi\ASNext_P3D\ASNext.exe"
start /b "" /AFFINITY 0x100 "D:\Program Files (x86)\VideoLAN\VLC\vlc.exe" --qt-start-minimized
start /b "" /HIGH "G:\Program Files (x86)\Lockheed Martin\Prepar3d v2\Prepar3D.exe"
powershell -command "Start-Sleep -s 60"
start /b "" /AFFINITY 0x100 "G:\Program Files (x86)\AirTrafficManager\AirTrafficManager.exe"

As an aside, I've rarely seen any of those "helper" apps use more than 20% of the core that they were assigned, except the GTN Trainer (which assigns its own single core affinity mask). The GTN tends to use 50 to 75% of its core, even with both a GTN 750 and a GTN 650 used in tandem. The powershell command just delays the start of the Air Traffic manager app until a SimConnect connection can be made to P3d. VLC media player is needed for the LAAP add-on which plays real time ATC audio streams automatically as you switch COM frequencies.

 

I've toyed with putting all three apps (TrackIR, VLC and ANS) on Core 10, but it doesn't seem to make a difference. Honestly, I couldn't tell you if all this "fooling around" with AMs has improved matters for me.

I know that feeling all to well jabloomf1230!! 

 

Further testing since I made the post to this thread - I do see a reduction in the slight stutters when ASN is running but they're still there if you look hard for them. It may be a case of splitting hairs at this point and to be honest, it sounds like there's some under the hood work needed on P3D's end for the weather/cloud component which once complete, will hopefully help the 3rd party weather/texture providers.

Hi Nels,

 

I've had similar issues with ASN in v2.4 also (regardless of the clouds used, Soft Clouds, P3D default clouds).  The ASN folks are good people, as are Opus and PILOT's FSGRW ... other's seem to be working well with ASN and v2.4 so it's likely some combination that's triggering sudden and drastic FPS drops.

 

I have yet to figure out why ASN is hit and miss on the performance front ... like you, P3D weather themes even Thunderstorms with heavy rain work well - no performance issues.

 

I've done all the usual diagnostics and isolated my environment so it's just ASN - removing all DLL.xml and EXE.xml entries except AS_connect, run ASN from another PC (networked) - I just can't seem to figure out what's going on with ASN.  Tried all kinds of P3D settings and still can't get consistent performance out of ASN.

 

I will keep trying ... ASN has a lot of settings.  I personally like having weather engine options and I'm looking forward to REX weather architect when that's released.  Perhaps it's a issue with the winds data in ASN?

 

Cheers, Rob.

Hi rob

I know this is an old topic

But I need your input please.

 

I am using your asn settings with enhanced overcast and thunderstorms ticked

 

Using ultimate realism pack settings just recently added on avsim forum

 

Using 2x sc Titans in sli

 

Flying through dense clouds 4xsgss an have tried dsr 2x with 33%

 

I get smashed through clouds

 

Textures are low also 512 clouds an 1024

Any advise please rob

 

Cheers

Mike

My ASN settings have changed a little, as has ASN.  Make sure you get the latest ASN beta build ... it's not in the usual place, but you can get it here.  You may also want to disable Multiple visibility layers, and turn OFF enhanced overcast.

 

What resolution are you running?

 

At 4K res with 8XMSAA dense clouds will make both my GPU's operate at 80-90% load.  4XSGSS AA will be a little harder than 8XMSAA.

 

Cheers, Rob.

 

EDIT: there is some minor optimizations for clouds in P3D V3.3.5, but it's NOT a huge benefit.

Thanks for your reply mate

 

Yeah using latest build

Resolution 1920 x1080 lcd 46 inch tv

 

No multiple visibility layers checked

 

But have enhance overcast and thunderstorms checked

Love my dense clouds

Tried 4xmsaa and 4sgss and cripples in heavy dense clouds

 

An have tried 2xdsr and 33% smoothing I get cripples fps

 

But usin no dsr and no sgss

And just 8msAa in game I maintain 30fps smooth as butter with same settings

 

Would be nice if LM or ASN or nvidia? Can implement an algorithm whereby clouds will not be affected by sgss?

 

I dunno lol throwing my 2 cents

 

Cheers

Mike

Turn off enhance overcast ... I still get full coverage overcast with this OFF (as in blanket can see anything but clouds for miles and miles) ... just make sure you have P3D Cloud density setting at max.

 

SGSS AA is not something that can be specified in the DX11 API, so it's nVidia exclusive option.

So, that means that we should live with this limitation forever?

Following.

What you want to live with is entirely up to you ... I'm just letting you know the technical aspect.  DX12 has no "specification" for SGSS AA, so that would be entirely up to nVidia.  If you surf the web, you'll see many "petitions" for better DX11 AA ... issue partly resides around the shader 5.x model.  

 

Hopefully nVidia's future generation GPUs will be able to work SGSS AA better, but either way, it's in the hands of nVidia or AMD.  But I think more likely path to better AA under DX11/12 will be via higher resolution monitor.  

 

Keep in mind this is HARDWARE ACCELERATED AA, you can do any amount of "software" AA, 32X, 64X (but at some point you get diminishing returns).  You'd NEVER want to do any type of software AA in a 3D sim/game.

 

Cheers, Rob.

 

EDIT: when I say "software AA", I'm referring to the CPU doing all the AA calcs/processing, not the GPU.

 

 

But I think more likely path to better AA under DX11/12 will be via higher resolution monitor.

 

Amen to that.  It was a great day when moved to 4K and shut off SGSS.

I moved to 1440p recently and it did not help at all :-) Perhaps G1080 will help
