Hey there,I'm having this problem...sometimes in some airports some parts of the scenery such as ground, terminals and some clouds are flashing. It's occuring in invervals of 10 sec approximately and only when I'm grounded. During the approach, for example, nothing happens. I took two screenshots to show you what's happening. I imagine it's not my video card that's overheating because my cpu is always open and I don't have any problem with any other software.Here is the normal thing:And here's the messed thing. It stays like this for ~1sec...Hope you can help me!My specs are on my signature...

Hi Patrick. Are the airports / scenery stock or are they added scenery? I notice the problem also affected some cloud texture(s). This could have several causes (single or combined): GPU settings conflict, FS9 configuration file settings, texture rendering problems in other words. A corrupt texture(s) and finally a corrupted graphics card driver. However based on,"'m having this problem...sometimes in some airports some parts of the scenery such as ground, terminals and some clouds are flashing." that implies that the problem is not 'global' or constant. I would suggest you go through all of you available setting and make sure that your "render to texture" setting(s) agree. For example; in ActiveSky and in your hardware setting in FS9. If you only find that you have the one in FS9 and it is checked on, you might try switching it off and testing to see if that has any effect. Or, if it is off try switching it on and see what happens. We can go from there after you try that. Please post your results.Regards,Mel

Hey Mel!Well first things first. Yes, I am using an added scenery and there's another thing that I forgot to say...I was trying to remember when and where it rappend for the first time and I realized that was in an airport 200nm away from that same airport I was when I took this shot and notice the problem. Well...in the first time things were different. The day was really hot here..something about 32, 35

Please check your 'render to texture' setting, if is set to on, switch it off. or if it is off switch it on, at least temporarily just to test. Load your Sim at the exact location as your screen shots and see what happens. I don't have any experience with ATI, but I thinking it may be an issue involving that setting and the driver for your graphics card combined with the texture you see used in your scenery. As a example, in your second screen shot some of the clouds (probably stratus) also seem to go dark. If it was a scenery only issue that wouldn't happen. Does what I see in the second screen shot happen over the entire airport including buildings or is just apron and taxiways? The important thing is to start eliminating possible causes. I have to admit it is a interesting problem. As far your thinking about your graphics card over heating, you most likely correct, easy to test, place your aircraft (use the same one as in the screen shot) as the same place. Exit the simulator. After you have shut down the computer and it has time to cool to room temperature, restart you computer and start the flight simulator, go to SELECT A FLIGHT and select "previous flight". See if the problem occurs right away. If it does then it isn't your ATI overheating. Sorry I am kind of jumping around from thought to thought but I'm just typing this as things come to mind. That said, are you always using the same airplane? If so you might try the same flight that produces screen shot two only with a different aircraft, for example if you are using a PMDG 737, try it with a stock 737 or an aircraft from someone else. Again just to eliminate possible causes. All of this may seem very tedious but it is the basic concept that we all use to trouble shoot problems in order to fix them. The reward will be flying any plane you like as long as you like and seeing your favorite airports the way they are supposed look. One last thing for tonight; have you recently installed any new cloud textures and what was the name of the scenery you downloaded? If all else fails, I am willing to install it myself and see if I can reproduce you problem.Regards,Mel

Also, disable the add-on temporarily and go to the same location. See if the problem goes away. If so we can isolate it to the add-on and can limit our troubleshooting to that. What is the particular add-on in question out of curiosity?Hope we can get you through it,-Paul

Good thought Paul, thanks. I whizzed right past that one. I must need a nap!Best to all,Mel

Well...I don't know if it happens only here but my FS simply doesn't loads with the Render To Texture off. It tryes to load, stops at 77% than crash. But anyway, I'm 99,9% sure that is not the problem.I did what you said...actually I loaded the plane at that airport to see if the problem shows his face but he didn't. I took off, made a visual local flights, touch and go's with the PMDG and AS6 and absolutely nothing happend. What a annoying stuff. It's not crashing my computer or nothing but in the first time I though that my videocard was passing away but then I made several other flights and everything was fine until I go to that part of the globe again. Wired uh?I have no words to thank you both for the time spent here trying to help me...thank you very much!If you have any questions about sound setting as I did with this scenery stuff please tell me.. :(

If you turn off Render to Texture you almost certainly need to turn on Aircraft Reflections to avoid the crashing.John

But what the Render To Texture is for actually? :(

You need it enabled if you use DTX textures or FS will not load.

If you are using the payware contrails addon "Contrails Pro", try disabling it. There is a known bug where it causes problems with certain ground textures...Geoff

Red,I have had all options off during testing many times .. render, shadows, lights etc loading aircraft with DXT3 (default Baron e.g.) ... no problems with FS not loading?Why would Microsoft allow an option to be turned off only to stop FS from loading?Or am I just missing something else?

Well I'm not sure how it applies to other textures, but I do know that if one uses DXT cloud textures (not default), then that option must be checked. If you use regular 32-bit textures, then you can uncheck it. I assume it would apply to other textures as well.

Red,Thanks for the follow up.I just have not seen the problem, "yet".I will just make a note to keep that option ON.Have a good day.

removed contrails pro and it solved my flashing ground texture problems. thanks geoffco!
