Several freezes only on 2nd/3rd/etc climbout of the day

Recommended Posts

Hi everyone!

 

I've been flying the NGX for as long as it's been out, and I really love it. Thanks for all the great work put in it! 

 

During all this time, I have experienced the following behaviour during most of my sim sessions: 

 

 

I usually fly multiple legs directly after eachother, with real turn-arounds etc., without stopping or reloading the sim - just like the real crews do. (I hate reloading it, because this reloads Ultimate Traffic 2, too, and I don't want that). 

 

On most occasions, when I'm climbing out after the second, third or fourth. take-off, I experience multiple freezes. They usually start shortly after take-off, occur about every 20-30 seconds and last 5-20 seconds each. Passing about 14'000ft it's all back to normal. Of course they're a pain, because I love flying the SIDs manually and they make it very annoying to do so and work the after take-off flows, too. 

 

Is this problem known and is there a solution? If not, here are some more facts:

 

- It only happens with the NGX. I've never experienced it with other addons (I don't own any other PMDG ones, but I often fly the Majestic Dash or the Aerosoft Twin Otter on up to 10 legs per session).

 

- It happens in the VC view as well as outside

 

- It *never* happens during the first climbout of the session.

 

- It occurs during about 80% of the subsequent climbouts

 

- I use hardly any scenery addons, so it's not them. It happened on isolated (standard FSX) islands in the middle of nowhere, too. I do use Ultimate Traffic, but it has on many occasions happened at airports with no traffic around. Nothing happens on the descent/approach into these airports either. 

 

- I just changed the weather engine from ASX to FS Global Real Weather and it didn't have an influence on the problem. 

 

- It's not caused by any complex SIDs. I had it happen on very simple SIDs or even at airports that don't have any. 

 

- Framerates are unlimited, and I'm usually having around 20-30fps, so normally my PC handles FSX and the NGX very well. 

 

- I usually don't have any FIXes or arches loaded in the FMC, so it's not that problem either. 

 

 

 

Does anyone have any ideas? What is different between the first climbout of the day and the subsequent ones? 

 

Any inputs are welcome! I have of course used the search function, read through several freeze/fps threads but didn't find any covering my specific problem...

 

 

Thanks a lot for your help.

 

 

Tis (flying East Midlands - Skiathos - Kavala - East Midlands right now, and it happened on both intermediate take-offs)

Whats your PC spec? 32 or 64 bit?

 

Have you applied the HIGHMEMFIX=1 in the CFG file??

i used to fly multiple legs with Maddog, without problems. With NGX i had some more problems then you - fly controls not working on second fly for example. I can't remember all issues becouse, since then, i don't fly multiple legs without restarting fsx. I think there is a problem with NGX, no fsx/windows/system settings. I don't have any solution unfortunately

Probably something with the memory. Sounds like fsx cant load it fast enough anymore after a while. Perhaps tweaking fsx helps.

 

You could search for HIGHMEMFIX for the fsx.cfg

Hi guys,

 

thank you very much for your fast and helpful replies!

 

As for the specs: I'm running Win 7 64Bit, 

CPU: Intel Core i7 CPU 970 @ 3.20GHz

RAM: 8GB

Graphics: NVIDIA GeForce GTX 580 (4GB)

 

Indeed I haven't applied the HIGHMEMFIX - I'm gonna try that one. Thanks for the input! 

 

I'm a bit hesitant to believe it has anything to do with the computer or the operating system, as it only ever appears during the climbout phase of the NGX and always vanishes shortly after passing 10'000ft. But well, you never know!

From my view this appears a bit strange, because even if there's a 4-hour flight after the climbout, no more problems appear afterwards. Not even during descent, when more details/textures need to be loaded. I'm led to believe that if your condition applied, I wouldn't be getting the freezes always and only during the climbout stage. 

By the way, the climbout freeze problem occurs regardless of the time spent flying before - it happened after a total sim running time of just 1 hour as well as after 4 hour legs...

But yeah, you never know. Thanks for the input, and as I said, I'll try the HIGHMEMFIX and report back. Might be a few days though...

 

 

Best regards and thanks again!

 

Tis

Don't think the Highmemfix  will solve  your issue since its only  related  to missing  textures of  aircraft etc,  but   was wondering if  you got  fsuipc  installed  since  that has  solved  many of the freezes  that users  were  having

If the problem continues after you've tried all the varying suggestions offered to you so far, I would reboot the PC after each single FSX session and see if that helps. I do this before commencing a new sector flight/session. As a result, my FSX doesn't suffer from OOM's, crashes, freezes, etc.

 

Rgds,

I have the same issues aswell freezes on climb out around 4000 feet for 2 mins then starts again no CTD either. Strange never seen before.

Solved. It turned out I was over clocked 4.8 and I reduced it to 4.6 and its stopped. So try that all.

I hate bringing this topic up again but I've experienced it in the past and now since getting FTX Global I'm actually getting an OOM message versus just a 1-2 minute freeze. The interesting thing was that I didn't change the view and I wasn't touching anything plus the plane was at around FL200. I admittedly run my settings hard but I'm using DX10 so for the most part I'm ok. Just wondering if there is any more to this or if it's simply an FSX limitation.

Are you running any photoreal scenery? If so turn off the ones you will not be flying over as FSX loads it all regardless of whether your near it or not.

 

Also, if your using REX textures set your clouds to 2048 (4096 is a huge memory hog and visually looks no different to 2048 unless your running a huge resolution monitor)

I don't use photoscenery and my REX clouds are 1024 DXT5. I'll have to test more as it might have been a fluke but even before this I've always wondered why I'd get freezes on the second leg of the session. Otherwise, everything's running well and I don't get OOM's in DX10.

It normally freezes because FSX has just loaded your entire 1st leg, and now your asking it to depart again and do another leg, normally the VAS usage (which controls OOM) goes down enough on its own to allow the 2nd leg, but sometimes, especially if your flying in a dense airport region like NY, London etc it just cant cope with both legs. I always recommend restarting the simulator between each leg - I know it break realism a bit but its nowhere near as frustrating as an OOM with 1000ft left to go.

Thanks, that's kind of what I had thought. I wasn't in a dense area at the time but unfortunately FSX is so old that it can go at any time.

I don't fly for a VA so I can't say, just probably push the sim a little too hard. I notice with FTX Global now it struggles a little more in these spots, probably related to the increased autogen. I'll do another test tonight to see if I simply freeze for 15-30 seconds which I can live with or if I crash again. I had to restart the program and I've seen errors in the past like this if it isn't the first time I've opened FSX in a session.

Just as an update/finding it looks like what happens is that the first leg goes fine, I sit on the ground for 45 minutes or so and then take off and when the sim goes to dump the airport and it's AI traffic it crashes. I'll have to take a look at some CFG settings but as has been said I think it's just a little too much for FSX.

I played around with this a little more and it is indeed the AI traffic that causes issues but I'm able to run it now, just have to endure a ~2 minute freeze when it goes to dump the last airport I was at. A little annoying but a small price to pay to fly multiple legs with high settings.
