Horrible performance when flying through clouds

Recommended Posts

So when flying through heavy clouds yesterday (AS16+ASCA) in the 737ngx my fps went down to 12-20 and when trying to look around in the cockpit it was lagging so much. When i got clear of the clouds fps went back to 30-50. This happens every time im flying through clouds. Is there any settings i can adjust so i wont drop that much fps?

Do you have any AA driven by nvidia inspector?  MSAA and those types of AA can crush performance in clouds.

I adjusted settings as Tony said, and haven't seen much visual difference. I also reduced layers of clouds down to 2-3. But, this is something that you're going to have to experiment with, to find what's best. All in all, there's not much to do unfortunately.

How does this affect performance in clouds? Does it diminish visuals? Is there instructions on where you can turn this off?

Download the New P3D Guide v1.0. It walks you through setting up P3D and AS2016. Look on the main avsim page on the right just under the picture of Tom.

Like the others wrote :

 

Try DXT 1024 instead of 32 bit 1024

If that is not enough , max 3 cloud layers and 512 clouds.

 

MA at 8 or 4

AF at 8 or 4

If you don't know how to turn this off you probably haven't turned this on so don't worry about this. To let nVidia Inspector drive AA you have to download a program and set specific settings. You clearly haven't done that so you can forget about it. And btw AA with Inspector improves the quality of visuals quote a lot but at too big a price. Unless you have a really up to date screamin' fast PC.

Also make sure you have installed one of the latest two Nvidia video card drivers.

What version of P3D are you  running?. If its anything less than 3.3.5 update to the latest version. The more recent versions of P3D solved much of the "cloud" FPS hit issues.

Thanks for the help guys.

 

AA is set to 2x Sparse Grid Supersampling in NI Inspector.

 

I've always had the problem with fps loss when flying into clouds but i will update P3D eventually.

That will induce an FPS hit with dense clouds unless you are running SLI setup.  Lower cloud textures and reducing P3D cloud density setting will also help.

Well, turn it off and see if it is noticeable to you. After all, that's all that matters. ;) 2xSGSS isn't a high setting but you may see a difference when you turn it off: some won't notice it, others will. It also depends on the resolution you use. Anyway, turning it off won't damage your system or cost you anything so try it to see if graphics get bad or not and if performance goes up or not (specially in clouds).

 

Questions like these are a bit useless on a forum (if you don't mind me saying so) because you will get different replies from people with different systems and different priorities. Only you can decide if a change is noticeable and worth it or not. I often get the idea a lot of simmers don't trust their own judgement and rely on forum posts to figure out what to think and like and so on... ;)

You're absolutely right, thank you :)

I used to have it off, and i remember that the GPU temp would be around 50 when flying. With it on im at 65, and flying through clouds it gets up to 71. I have no idea why i turned it on again, probably because someone told me i would lose some effects or something like that.

That is normal for a GPU..., temps up to 80C are considered "warm" but not dangerous.
