I recently had to re-install my operating system. After re-installing FS9 and my video card drivers, I am noticing a problem with the terrain visibility.The problem only seems to occur when flying under approximately 10000 feet. When on the ground or under 10000 feet in the cockpit view, everything is fine until I switch to either a side view or a spot view and then the screen flashes and the terrain textures turn blurry. This seems to go away aver 10000 feet.My video card control panel is set at 4x anistropic filtering and 6x anti-aliasing.The game settings are mip-mapping at 4, with rendure to texture and reflections both checked.Any assistance with this would be appreciated.ThanksRoger Hollands

Help!!--Anyone??

Sorry your post went a day without someone noticing. If this is a hardware issue, post your system specs just in case.Sim wise, when you switch views, what happens to the textures if you keep your view fixed in the new position for a few moments? Do the textures clear up, or remain blurry? Also, why the reinstall? Was there any issue which made you decide to reinstall? Did you defrag after the reinstall? (a must for MSFS).-John

John:Thanks very much for your reply. I did also post in the hardware forum but no answers there either.My specs are as follows. Athlon 2.6 gig processor with a 1000 mgb of RAM.Not sure about the motherboard.Video card is Radeon 9800 pro with 25767 drivers. I know they are not the most recent however they were the ones I was using with no problem before the reinstall.As to why the reinstall of the OS--I was infected with multiple viruses acording to my computer guy and the only was to eliminate the problem was to reistall Windows and then FS9.As far as do the blurries change back again--no they don't, but the problem does go away after exceedeing 10000 feet.I am wondering if this is a .cfg issue.Any assistance or advice is appreciatedRoger

Hmmmmm.... Can you post a screenshot? I'd like to see exactly what the terrain looks like when you see the blurries. I'd almost think that your default visibility is the issue since 10,000 feet seems to be the cutoff. I would load another flight from one of the defaults and see if you have the same issue. -John

John:I am somewhat new to this and am not sure how to post a screen shot within this forum. If you can help me, I will certainly try.Roger

Save your image as a jpg, no larger than 1024x768.Then, select Reply:Select the Link: "Click here to choose your attachments"Browse for your jpg image check boxes "JPEG Image file" and "Check this box if you wish to embed attachment url in the message text box"Select "Upload File"Close when prompted after upload and submit your replyHope that helps :)-John

John:I am using FSSCREEN for the screenshot and it exceeds the size limit for this forum. I am trying again with another plane.Roger

John:We may be on to something here. When I use the default 737, this doesn't seem to happen. There is no switch to the blurries using the side or spot view.Any thoughts as to why this is and how I can fix this to work with the PMDG planes.Roger

Paste the screenshot into an image editor like MSPaintbrush and scale it back until it fits within 1024x768, then save it as a jpg.You should be able to upload it then.-John

Roger,I have seen this problem happen with both scenery and aircraft addons with and ATI 9600XT, a GeForce 6600GT and now on the 7800GT.If the problem is only on one aircraft (ie it does not happen on the default) then the problem is likely due to a corrupted texture or corrupted texture memory only associated with that aircraft or aircraft with a similar texture load.As you recently re-installed windows and its XP, then there is a very real possibility that a newer driver may fix the problem as there have been some rather large updates since the date of that driver and they would have likely (or should have been by your tech) installed before the driver. The older driver may not be not coping well with them.The corrupted texture memory can be due to it running out of vram and going to sytem. There are very often undetected memory errors that are never a problem because nothing actualy goes to those areas except under unusual conditions. But once in a while, something hits that bad cell and thats it. In the old days the system would just crash. At least now you know the hardware is taking a dump on you and its recoverable.If its happening on all aircraft in the sim then heat might be the cause of this as large file sizes and high loads cause the memory to warm considerably and the ability to recover from a bad texture or memory error decreases. The extra heat that was not there yesterday may be due to the driver or the OS making mistakes and having to repeat actions.Again another reason to update a driver as a first step. In windows, even today, driver order on install is very important. Some machines prefer sound to be installed first, others vid... it keeps us techs in business heheh ;)There is an application called memtest86 that will test system memory, and there is a variety of GPU and CPU warm up tools that will show you where the error is.On my site, under Downloads/Utilities are some video card tools:http://www.ascendant-online.net/en/downloads/os.php#videoGrap ATITool and run the artifact scanner and warm up tool. then read the docs. It will tell you exactly where the system is having trouble and what to do to fix it.CheersShad

Shad:Thanks very much for your input. As I have limited knowlegde of these things, I am going to try a driver install first.Based on my card(Radeon 9800 Pro 128 mg ram) do you have any suggestions.as to the best drivers?Roger

Sadly the problem I am facing with the older cards is the newer drivers are not really taking them into full consideration and have recently been introducing more problems than thay have fixed it seems.Here is what I would do (im mostly insane though). I would actually go to the archinve and find 5.7... it seemed to be the best. August last year vintage... but you may need the newest.Uninstall the old driver first and restore the ms default.Edit:Here,I added it to my site for you:http://www.ascendant-online.net/en/downloa...p_wdm_24085.exe

one last thing Roger.. with a 9800, I would keep AA in the driver to 2, AF to 8 and mip maps to max in the sim for best results. Your card is more than capable of dealing with the mips and shaders but 6x aa is overworking the poor thing.Cheers and good luckShad

Shad:Thanks for the advice. Will re-install your drivers tonight and thanks for your help.Roger
