Delayed texture loading - user aircraft and VC only

Recommended Posts

I have had a problem for a while that I simply cannot seem to solve. I have been having a problem with textures taking a long time to load, both with the user aircraft seen in chase view and the virtual cockpit. It doesn't seem to happen with scenery or AI aircraft. In the case of the VC it means that when I change to VC view, every now and then, all I get is blank textures with only the instruments showing. At the same time, when I switch to external view I either get completely blank textures or in many cases, the texture for the rear part of the fuselage is blank. It usually only lasts for about 15-30 seconds.

 

I have fiddled with my video card settings. I am using tried and reliable fs9.cfg settings that used to work perfectly and just to be sure, I used a backup to make sure that no settings had been accidentally changed.

 

I have also had some very slight pauses loading scenery textures but it is infrequent and probably not related to the problem described above.

 

Any ideas would be gratefully considered....

Sometimes i get this, but it only lasts a second or two. I added more memory recently and it stopped doing that completely, so maybe it is RAM related?

 

Only other obvious thing i can think of is something might be writing or reading from the disk in the background slowing the process of loading the textures data. I don't think FS9 caches these textures so when you swap views they have to be located and loaded again each time.

system specs?

I wondered about the possibility that something else is reading from the disk. But unless it's something that has been inserted into FS then it could only be happening on the C drive as the D drive (1 tb SATA) is exclusively for FS and related programs. I will keep looking into this though as it makes sense as a possible cause of the problem

Thanks

How long has it been going on for? Viruses often write/read to an infected disk constantly and can be a source of a data slowdown.

I looked at that thread but couldnt find the folder you mentioned. How do i find it? It isn't listed under the address you posted.

I'm running XP SP3, later versions will be the equivalent folder.

Google (Not Earth!) is your friend here.

The major cause of this is:

32 bit textures

32 bit textures with no alpha channel

DXT3 textures with no alpha channel

 

So that would be the first place I would check.

Maybe that program in your sticky that you used to regenerate the alpha channels has caused a problem with them?

Exactly Tommy especially if it is in one or two planes vs all of them...

 

Nah, I would guess they are 32 bit textures to begin with not DXT3 and they may need a run through the dxtfixer just in case.  No reason to assume that would break anything.

I suspected a texture problem but it happens no matter which aircraft I am flying, including the default Robinson. I am continuing to check all my textures for missing alpha channels etc and have certainly found some, but so far it hasn't made any difference. I will keep searching

Hope you find a solution bud. There's nothing worse than a crippling problem that doesn't have an obvious solution. Keep us informed.

Maybe your " TEXTURE_BANDWIDTH_MULT= " in fs9.cfg somehow got changed ? That used to make mine do that with certain aircraft / scenery.

Hello

 

I was going to suggest this as well. I suspect Ian as an experienced simmer will  be well aware of the texture bandwidth entry ,but nonetheless all suggestions are usually a good idea in the event of a problem like this.

Cant believe a supersonic setup like Ian has is experiencing this sort of thing in nine, (X yes perhaps) but nine! a mystery indeed Holmes.

To narrow down the potential causes I suggest to disable AI traffic altogether and try a situation where you know the problem occurs (if that's possible).

If the issue goes away you will know that it is not related to AI traffic airplanes and associated textures. Then it's probably a scenery related issue.

Or, if the issue stays, you know that one or more of the AI textures need adjustment.

Good luck.

Thanks for all the good suggestions guys. I'm not sure I have nailed it completely, but one major problem was that something I downloaded a while ago offered me a link to the latest and greatest Nvidia driver - except it was actually an old and out of date one. I have now restored the latest and greatest Nvidia driver and things are working a lot better. I've managed to eliminate a number of possible causes but I have a feeling I'm going to find one other thing that's been adding to the problem. But the video driver was definitely a major contributor

Cheers

This is really starting to bug me. I have eliminated all the following possibilities:

1. fs9.cfg... I am using exactly the same settings that a few weeks ago was delivering flawless performance. I have used a backup copy to make sure there were no corruptions and have checked through it all entry by entry. It is configured exactly as it was before this problem began

2. As stated above, I have replaced the driver with the latest NVidia version

3. AI on or off makes no difference

4. Whichever user aircraft it is makes no difference

5. I have checked all my texture files for missing alpha channels

6. My settings are the same as they have been for hundreds of hours of faultless performance

7. I have defragged and run Norton virus check

 

The only thing I can think of is the NVidia settings. As they were changed to default settings when I installed a different driver, maybe I have the card configured wrong. But I've tried tweaking it and so far no result. FPS and texture clarity are excellent. There's no problem with scenery or weather. It only happens when I switch views to chase and to VC - I get a pause of 30-45 seconds with no aircraft or VC textures...

Grrrrrrrrr - I hate it when stuff like this happens and I know when I find the culprit it will be some silly little thing...

 

Any new suggestions would be gratefully accepted.

Do you fly with a real weather provider/tool, like FSmetar or something like that?

Try to switch it off and see if that has an effect.

I do use ASV6.5 but only occasionally and in this case when I'm trouble shooting, not at all. Thanks for the suggestion though

Hello Ian
I can't believe this is a driver problem ,over the years I have used all sorts of drivers ,I have used the latest ,used earlier versions ,gone back to the latest etc etc etc and in all that time have never really noticed any change in performance either for the better or worse really ,the sim just continues on its merry way.
If as you say the delays in loading textures are in the 30 - 45 second range then that is a REAL big deal. Even if i used 32bit textures on my old (seven year old ) single P4 2.8 I would not get a thirty -forty second loading (I always use DXT3 by the way).
Wish I could help Ian. The only other thing that might? be worth trying (you may have done this already) is to get one the advanced uninstallers I.E. like the one that comes with I-OBIT's systemcare prog. Unin your GCard driver making sure you select the option to remove all traces of that driver, and also any other driver versions you may have as well.(Then Rein whatever driver version you are testing) Some suggest that there can be conflicts between co-existing current and earlier versions drivers on one PC.(Have to say though that I have had more than one driver version on my PC with no issues)
BUT! in these difficult to solve cases I always feel any suggestions are worth a go particularly in the case of extreme S.I.D (Simmer in distress)

Cheers Andy

PS Ian I (and this is only my opinion) would be very surprised if your problem was anything to do with ASKY or any other weather programs.
The only time when I notice big performance issues from one day to another is if one flight is say in middle east (less detailed airports /or dense scenery/less A.I. in area= lovely smooth flight.Next day may fly in Europe UK etc and that usually means less smooth for the opposite reasons.

Cheers A.

I am now checking to see if it's a problem with a particular addon scenery. Why that would cause a problem with the textures in the user aircraft I have no idea but there may be a scenery that's setting up a conflict between that is taxing my system and shows up when I change views...

Thank you again to all who have tried to help

Ian
