I seem to be full of complaints today so apologies but I am getting drastic visibilty changes when flying over Sydney today - see screenshots - with this metar. Below about 4200 ft vis drops to what it is in reality if you look out the window - the weather today is really quite foul, but above this alitude in an instant it turns into a fine sunny day!!YSBK 300400Z 05021G32KT 3500 -RA FEW015 SCT022 BKN030 17/14 Q1019 FM0400 04025G45KT 8000 -RA FEW015 SCT025 BKN040 TEMPO 0400/0700 4000 RA BKN012 All defaults except FS haze which is disabled and ASV build 325.Realistic visibility variations has been an ongoing hassle for me, I've posted before on this and so far there doesn't seem to be a satisfactory fix.Bruceb

You were not showing your framerates - I'm getting similar problems, and although my framerates are normally more than satisfactory, we all get those unexplained temporary slumps and I'm wondering if it's FS' tendency to drop detail when frame rates go below a minimum level.My problem is that I want to retain distant haze to hide the horizon and the "ring of clouds" effect when you fly at high altitudes.This is more realistic - flew from Stansted to Dublin on Monday - beautiful day but still couldn't see a sharp horizon. Back on Tuesday in the thunder and lightning, but that's another story!

Hi Bruce,You are experiencing the FS04 situation where if visibility jumps from below 9.999SM to above, that this is going to happen. Damian has addressed this in the past! It can help if you limit your maximum visibility to 30 or 40.Also, there is no OVC in the METAR in order to draw a mostly solid cloud layer.Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg

Hi ai,You need to limit you maximum visibility to 30 or 40. For the ring of clouds. increase your cloud draw distance in FS, but be prepared for a FPS hit.Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg

The information you list doesn't seem to be a METAR at all. It looks more like a TAF, and even then it would be slightly malformed.

The metar was pasted from the AVS dialogue box - it was what AVS gave as the metar at that time. JimAhhh, the dreaded 9.999SM bug! So there is no way of getting visibility to work in FS9 as it does in the real world? If it is 2 miles on the deck no matter what you do with any settings this is what you get up to a certain altitude then bingo out to your maximum visibility right down to ground elevation. Not quite sure how limiting your maximum visibility can help with this very annoying 9.999 problem - seems counter intuitive. However, I could accept that setting minimum visibility to 10 miles or more would help at the considerable cost of reducing realism a great deal.Would it be possible to have an option for ASV to insert a layer of overcast regardless of the metar when visibility is below 9.999SM? It would make things more realistic if the sudden increase in visibility to above 9.999SM came after climbing through an overcast layer.Bruceb

JimDon't seem to had a response to this now somewhat dated post so I will try again.Bruceb

Hi Bruce,Not exactly sure what you are looking for!Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg

OK I will try to spell it out. 1. How does "It can help if you limit your maximum visibility to 30 or 40" help with this visibility issue? As I said, it seems counter intuitive to me, perhaps you could spell out this one.2. Would it be possible for ASV to have an option to insert an overcast layer when visibilty at ground level is below 9.999 SM so that you could have realistic looking climbs through layers of low visibility in to clear air without the undercast magically vanishing?ThanksBruceb

Hi,OK I'll give it a shot!1. Because then the jump is not so visibily shocking. It blends a little more.2. Honestly, I am not sure. From what I understand all that would do is delay the jump until after you clear the fake overcast layer.What I am going to do is mark this thread for Damian to visit, to either post and/or to be aware!Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg

Thanks JimI guess the fake overcast could remain until a metar was loaded with a surface vis greater than 9.999SM - just a thought, maybe there isn't a satisfactory fix for this issue but it sure keeps coming up a lot in this and other forums.Bruceb
