ASN fps drop in dense clouds.

The max visibility issue is an issue  1) ONLY if you have volumetric fog enabled, 2) ONLY if you are on 3.2 and 3) ONLY if you notice it! I venture a guess from reports I've read that most users have no clue what the problem is and wouldn't recognize it if it bit them. Not an insult so please don't jump in with "Well, I see it!".  Many people DO notice the issue and it bothers them - which is why HiFi is making changes. But a great many of us haven't noticed a thing. If you like what you have now, you can use the latest beta and just do not enable the new option.

 

For me, I have no visibility issue - if I set vis at 100 miles and when I'm flying it looks more like 60 miles - so what? It still looks great, so I keep flying.

 

I am NOT demeaning those with serious issues but I really do think there are some that are nit-picking a bit on some of this.

 

Just enjoy what we have!

    I found that disabling volumetric fog helped my FPS to be playable in dense cloud situations. Also, gave my proper blue sky back.   Take it with a grain of salt though. I haven't done much testing t

    Volumize works - thanks for that but clouds definitely dont look as good either - its all good - nice to have options at the moment I am using  //

Mate I am using max visibility with volumetric fog cloud layers 3

 

And like you sai I don't spot anything unusual looks great. Well after adjusting cloud.fx to 0.50 frames are up again.

 

Would you recommend me installin the latest asn build? 5926?

With my settings?

Does the VOLUMIZE tweak also turn off volumetric fog or does it just impact the softness of the cloud textures?

It doesn't affect volumetric fog. It only affects the clouds, but I haven't noticed anything visually from disabling it. Plus, I am able to increase the sprite size to larger sizes with less of an FPS hit when it's disabled, which helps to reduce that ugly popcorn cloud effect.

Nonetheless, I turn off volumetric fog too. Not only does it hurt my performance in overcast, but it messes with the true color of the sky.

Below the overcast layers, I don't even see a huge difference with fog or off if my ASN is configured correctly.

This is a Rex 3 cloud set, so IDK how it would look with REX4 or Soft Clouds.

I have P3D 3.2.3, ASN B5926 setting to default but with 3 cloud layers and "Multiple visibility layers" on, REX 4 + soft clouds with cloud size 0.67, no Volumize tweak, and all works fine.

Really? With 0.67 in live mode ?

If you use the Volumize tweak with Softclouds you probably will not notice any difference.

If you try it with cumulus set you will see them become softer...

Well, Mikey I would agree if I was flying low, like in the planetary boundary layer, where lots of dust and haze lay. That would produce a similar milky sky color if volumetric fog was on.

 

However, those shots were at 20,000' MSL, well into the free atmosphere where the air is much clearer and the sky is darker and a more pure blue. So I find volumetric fog is only appropriate for certain conditions.

Interesting conversation as I updated to 3.2 and saw a massive performance hit when heavy clouds were present (using ASN with latest update).  I wasn't sure what was going on and I ended up changing my Affinity Mask.  This improved things but I still am not back to where I was on P3D 3.1 regarding FPS.  I do use REX so will try this cloud size tweak and report back!

It would be nice if the fog faded in and out through certain conditions.or altitude?

Thanks. 

Thanks. 

 

I guess I may want to add that I use only three ASN layers at the most. This will help performance. I find that more layers usually creates more distracting, cloud behavior. I'm a bit of cloud nut, so having it right is important to me.

I found two entries in cloud.fx:

 

#define VOLUMIZE
#ifdef VOLUMIZE
 
and changed it to:
 
//#define VOLUMIZE
//#ifdef VOLUMIZE
 
I guess that is ok now?

 

EDIT: NOT OK, lost clouds completely in the sim. What I did wrong? I also deleted shader cache prior to launching p3d again to see differences.
