Does P3D 3.3.5 appreciably help with the performance of clouds?

You may also want to disable Multiple visibility layers, and turn OFF enhanced overcast.

 

Please can you advise where the setting for "multiple visibility layers" is? I don't see this option in ASN or P3D?

 

Thanks,

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.

 

Cheers, Rob.

Thanks mate

Will untick enhance overcast and give it a shot.

I also have high detailed thunderstorms checked should I uncheck it?

 

Also with max lower visibility setting 15m

 

And max upper visibility at 63 is that typical to realism?

And cloud draw distance? I have mine at 90 ATM

I am on 3.3.5 now and confirm the issue still exist. I have reduced layers from 5 to 3. No luck. Frame rate drop is 50% For me those drop from 30 to 11-12.

 

Though I see slight visual improvement (in wing views) on clouds especially when plane is passing through.

I always thought the frame hit was because ASN knows when you enter a thundercloud and rain or hail come your way. I do not have this frame hit when flying through 'dry' clouds but generally only when going through some severe weather. Once behind me, the frames are back to normal.

Yeah, that's what I get in 3.2. 

 

EDIT:  Actually, the frames aren't quite that bad.  What is bad is the stuttering.  I can usually fly okay with the frame rates I'm getting...the difference is the stuttering gets really bad.  I'll have to try some tweaking and, perhaps, try REX Essentials instead of ASN, etc.

I had good cloud performance increase when commenting the #Define Volumize in cloud.fx before P3D v3.3, but seems this has been removed definitely from the shader code... not sure if it's enabled or disabled by default now..

As advise by rob earlier in this post

ASN

I have major thunderstorms checked

Multi visibility layers unchecked

Cloud layers 3

Enhance overcast unchecked

 

 

Getting smooth stutter free through heavier clouds in storm

With 4xsgss and 4msaa inp3d

 

 

Rob was correct enhance overcast checked in asn will cripple performance

I believe REX and HiFi are both working on ways (updates or new products) to do better overcast with less of a performance hit ... so there is some hope we don't have to make this compromise in the future.

 

Cheers, Rob.

Is it advisable to get the latest build release or latest beta as it stands now?

That's great news

Looking forward to it

Here's something to try: Don't install REX soft clouds but choose another cloud set. I noticed a very bad performance hit using soft clouds when flying through them. Then I installed 2048 cloud textures and did the same test again, no fps hit. Although soft clouds are lower res. textures, there's something odd about them.

The logical "trick" is to always use the cloud-sizes EXACTLY the same as defined in P3D as the TEXTURE_MAX_LOAD=xxxx value.

(If one uses 2048 as max texture size but has a lot of 4096 textures - either scenery or anything else - those bitmaps need to be down-sampled by the video-card at runtime).

Soft-clouds are 512x512 in size so they need to be up-sampled if a higher max value is used.

 

Whereas up-sampling (in some special cases) usually does not cause any performance hit, down-sampling a lot of bitmaps will definitely have its affect, as larger bitmaps take video-memory and good amounts of cycles for the sampling process.

That's why it is the best to always stick with the same cloud sizes as the max texture size value being defined.

Just wondering if anyone has already had a chance to test 1080 in P3D environment.
