FSX seems to be working well and smoothly overall, except for an annoying issue to do with

peridocal flashes/flickering of the sky immediately above the aircraft, the best way to describe

is to compare it to a sort of white strobe type flash. It doesn't happen all the time but does

appear at random. Not been able to find why this is happening. Any advice/solution would

be most welcome.

 

Thanks

Weather engine? Simconnect and weather engines can cause this, REX claims it is a traight of simconnect.

Rendi is spot on. The weather updates when not running any DWC mode can cause the sky to flicker or flash. The intervals experienced may therefore represent the setting on the weather update timing.

Thanks for the quick replies. I do use REX and ASE.

 

First I load the flight plan on REX and send the REX textures to the Sim, then when this process

is finished, I load the flight plan on ASE and let it create the weather, etc.

 

Is there any way to solve this issue?

I don't see this with AS2012 and FEX. I think you need to pinpoint the culprit. Like on your next flight don't use REX and the next flight don't use ASE but the default weather engine, etc. CoolP may be right on too with the weather update timing. Maybe changing it to static will eliminate the problem then you can go to the appropriate developer and see if there's a fix.

 

Best regards,

That flashing is from injecting weather into FSX via Simconnect, regardless of the weather soft in use. You can only avoid it with running your weather app in the so-called DWC (direct weather control) mode.

 

For example, in ASE there are three modes to choose from. One makes use of DWC, the other two do not and may therefore involve the downside but also advantages over the DWC thingy in other aspects. Hence the ability to pick your favourite or just the one involving the lowest amount of downsides for you.

 

You can work around the issue with the slightly longer update intervals or by using the faster REX-E injection (compared to REX). This will limit the time of the flashing to very few seconds as REX-E does not make use of the DWC mode. Other than that, there won't be a fix.

 

That's only from my humble knowledge on the ways of the FSX weather cell system. But don't hesitate to ask the devs, although I believe that they will tell you the same. With REX-E, the flashing is very short in my eyes.

Did set ASE to DWC and so far no flashes, keeping fingers crossed!

 

Thanks CoolP and everyone else.

CoolP, what are the other aspects? I'm trying to fine tune AS2012 to my short VFR flights in RA Lancair Legacy on PilotEdge, to some reason it makes the wx a little too cloudy in the area I fly the most (KSNA, KLAX, KONT), compared to the real wx reports. Sometimes even difficult to VFR.

 

Thanks,

Dirk.

 

PS: I use REX+ OD clouds in 2048 res, DX5 Optimized, but I guess the slight problem is with the wx engine, not textures.

DWC in ASE/2012 is best suited for high alt airliner flights. For VFR flying, the standard setting is best. But as CoolIP stated, you will get the simconnect issue in the modes other than DWC.

When running ASE, I have DWC enabled too. The only quirks I see with ASE aren't related to the actual mode though, so I guess sticking with Julian's description on how to pick the best one makes sense.

 

I can't speak for AS2012, but I guess that

to some reason it makes the wx a little too cloudy in the area I fly the most

may not be related to the mode in use. However, if you can pick different modes, perhaps take some flights to tweak and fiddle with any of them, just in case.

 

If you end up with none of them being the optimum but all just involving different ups and downs (literally), I think you might have spotted the very nature of the beast. Though I doubt that this is a special ASE/AS2012 problem, but more of a character trait of the FSX weather system.

I think it is something to do with the way the weather was updated. There is no need for the flashing as one traverses between weather areas. Instead a different approach is needed, but with it there can be some movement in cloud positions after updates, depending on time/windspeed etc.

 

Sometimes flashes are caused by lightning in the distance, also one can pass through the edge of a cloud just clipping it momentarily, also one can pass between visibility (haze) layers, but all of these are usually obvious when they happen.
