***Flashing Sky/Clouds***

Recommended Posts

Hi allI have noticed this last night while I had Dynamic weather enabled ( FSX Default - not ASV6 ) . The sky/clouds infront of me "Flashes" randomly for about a half a second,. Almost like a very quick dark flash of some sort but very briefly and every few seconds. I have read other users experiencing similar issues but after a search on this forum, couldn't find an exact match to what I am experiencing, but the symptoms are the same.Anyone else experiencing this, and what might be causing it ?I'm running Forceware 93.71 drivers.Thanks

I had the same thing a couple of weeks ago. Not sure what caused it. I would see a flash for a second every 8-10 seconds. To me, it has to be a driver issue. I would experiment with a few. It could also be a setting in the CFG if you have edited it. I really wish I could help you more, but mine is gone now and the only thing I have really done is change drivers. I am running the second latest, forget the version right now.duttonhttp://dutton.fsblogger.com/

Using real world weather, I experienced something similar. It only happend when I was facing the sun. The clouds would blink in & out. If I looked away from the sun everything was OK. I solved it by turning off lens flare.Jim

You are not alone.I, too, am experiencing the same problem. It doesn't always happen but when it does it will be a lower altitudes - under 2000 agl or so. I figured it was a driver issue as well and experimented with various Nvidia drivers but no luck resolving it. I haven't noticed if it occurs when I'm facing the sun or not but will definately try turning the lens flare off.

How about that! After typing my message above on the laptop, my PC started to do this very thing again. I was approaching Unalaska in the Lear with real world weather on.Taxiing in, I turned off the weather and it was gone, the flashing that is. I am going to do a bit more testing but it appears to me when there is a low haze/stratus layer and you are in it, this happens. Remembering a bit more back to when I saw it before, it was always on low flights so this makes sense to me.duttonhttp://dutton.fsblogger.com/

Same here:First I thought it was lighning, but looking at the METAR for KSFO, there was no convective activity. Looks to me like a "bug".I'm running Vista RC2+ATI Vista RTM drivers

Yep, just did some testing. I am only seeing it with a layer of stratus and when I am 'in' that layer. Does not appear to be relevant which direction you are flying - away from or into sun - at least when you are in the stratus layer.duttonhttp://dutton.fsblogger.com/

Yes, exactly the same experience here...flying low and in reduced visibility with stratus cloudsBloom isn't enabled for me..will check lens flare..I am seeing some white flashes now with ASV 6.5 and bad stuttering when weather refreshes, just installed beta build, so will test now and see what happensACES are you aware of these flashing issues ?Many thanks..

To me this happens when i overclock the graphics card beyond a limit. Don't if thats the reason for you all.

Nope, I don't overclockFlashes are happening when using ASV also, only in the beginning when it updates wheather though....Massive dip in FPS when wheather get written to FSX.... and heavy stuttering..... once wheather is updated all goes back to normal speed....there must be something wrong between FSX and AS6.5

I am pretty sure it is an "undocumented feature" (bug) of FSX. I have had the problem since the demo and beta. Peter Dowson is aware of it and I think he stated it is Simconnect issue. Of course my memory is a brain connect issue and I might be remembering it wrong. :)Bob...

Has anyone solved this? It's ruining FSX for me. I get it reliably nearly every time I fly as I fly on VATSIM 90% of the time and they seem to almost always have haze layers (for whatever reason).I've had 3 different Nvidia driver versions, tried all types of settings, turned features on and off, all to no avail.The only "fix" is to turn off weather when it's around.I know Nvidia engineers and have pointed this out to them but have gotten no response from them on it. Clearly their a bit busy with a laundry list of bugs already.I'm new to Nvidia after years with ATI and this certainly isn't a good way to start out with them.I even swapped EVGA cards to no avail.

Hi Rich,If it's any consolation, I had the same (or similar) problem with my ATI card. Have you tried creating your own weather? For me the flashing only occurred when I used real (downloaded) weather; I could set up complex multileveled clouds within my own weather themes and everything worked fine. Try it and see.Have you installed SP1? I have not seen this problem since I installed SP1. In fact I have considered uninstalling SP1 but have resisted the urge because of this problem.R-

As I fly mainly on Vatsim, creating my own weather would be a bit problematic. It wouldn't match what everyone else was seeing.I do indeed have SP1 installed which is what concerns me.

IIRC it was mentioned in an earlier post that this issue is related to being near the interface to two weather layers (vertically). its the visual equivalent of the almighty wind shifts. I suggest that if you get it on a flight then redo the flight, if possible, with no weather and see if the issue re-appears. Another experiment would to to gain altitude quickly if it appears and check if it stops. I have experienced this some time ago but haven't seen it recently and I haven't changed my graphics card or drivers.

It does indeed stop if I clear the haze one way or the other but that's no solution. If haze appears onscreen it will flash. In VATSIM haze seems to be a nearly constant companion so there's little escaping it.Obviously haze is not meant to flash and certainly not every time it's evident.I may re-install again to see if perhaps something with SP1 didn't take for some reason.

Quick query, I have never seen this on my Nvidia 8800GTX however on our test machines running a 7 series we have encountered this very issue. Would like to ask how many users posting on this thread with this problem are running a 7 series Nvidia card?The problem appears to be one of Z-drawing when you have lots of alpha textures overlaying other alpha textures, such as is the case with clouds.

I get this too - seems to effect Stratus layers for me. I have tried several drivers with no change. Don't seem to remember ever seeing this prior to SP1 however.BTW I'm running a 7600gt.

I had kind of expected this to be manifest with a common denominator such as a particular card or driver verson but from the responses I guess sadly it is not that simple (at least so far! there maybe a common denominator just havn't worked out yet). I have yet to see it on my main development PC.. so something strange is going on.

I'm going to get a FRAPS recording of it and have a lead Nvidia engineer looking at it. We'll see if that helps.Did someone say they saw this on ATI??? If so, that's not good news. That means it's MS and they seem to feel the game is just about done. I can't imagine years of looking at flashing haze.I've also sent several requests to Aces team members begging for any help on this issue and have not even gotten the courtesy of a single reply.I have time this weekend so I'll find out if I get lucky with a complete re-install.
