Hello!

My simulator was working perfectly in the past years, high settings, high FPS...

Over the last few feeks I was getting more and more problems. I started getting more and more DXGI_ERROR_DEVICE_HUNG errors (usually with FSLabs and sometimes with other addons) and more CTDs. It is interesting that P3D (v4.5 Hotfix 1) runs very smooth when this happens. There is no indication that something is wrong or GPU is overloaded. GPU has temperature range about 55-65 (celsius) all the time and I have never overclocked it because it is factory overclocked. 

Aerosoft CRJ has been always the most stable addon to fly and I haven't had any crashes for a year with it. But today I was on departure in LFPG flying to LJLJ and P3D closed without warning above Paris and it was a terrain.dll.

The only recent change to my PC was an additional fan at the back of the case. I also started using Tomatoshade and installed modified MDL with reflections (only Aerosoft CRJ) and there was no performance impact.

What problem do you think it is? Is GPU overloaded, is my GPU failing...? I am thinking about RTX 2070, will there be any improvements?

 

PC specs:

i7-7700 (running at 4.2GHz)

KFA2 GTX 1060 3GB

16GB DDR4

240GB SSD (Windows drive), 500GB SSD (P3D dedicated drive)

1TB and 2TB HDD

Gigabyte G750H 750W 80 GOLD PLUS PSU

 

Thank you very much for answers!

Did you test if flying completely without Tomatoshade prevents the crashes? Shader software are not a slight change to the simulator, they interfere quiet drastically with it.

I assume you deleted the shaders after installing Tomatoshade, no? Personally, I always delete the shaders after each and every shader modification I did... Sometimes also rebuilding the prepar3d.cfg helps to get rid of slowly decreasing P3D stability.

Then, how old is your PSU? Sometimes, unexplainable crashes can also be related to a partially defunct PSU (this would however not explain the terrain.dll crash).

In my case, I got DXGI crashes only due to the framelimiter of the nVIDIA Profile Inspector. Since I do not use this limiter anymore, no crashes due to DXGI. Do you use the nVIDIA Profile Inspector?

Last: if you have any ORBX product installed, you could also try once the "force migration" option to see if this might correct any errors that might have accumulated over time.

Regarding DirectX......

Over the past couple of months I had been having issues with very slow scenery loading and unexpected computer crashes (although not the DX error as far as I know).  I run a WideView setup and all 3 client computers exhibited the same issue....

Then last week the latest version of DirectX auto-updated to each of my computers.  The only reason I was aware of the auto-update was that the DxDiag window appeared at bootup (strange I thought since I had never experienced that before).

In any event ever since that update my system has been running like a dream.....massively improved scenery loading, minimal stutters, and no crashes thus far. 

So I gave it my ultimate scenery stress test:

KEWR (Drezweicki airport plus New York area scenery) -> CYYZ (Fly Tampa) -> KBOS (Fly Tampa),  weather was conveniently heavy throughout due to the heavy storms in the NE that night.

Performance was like a dream!  No issues!  Better then ever!  Same result on each of my client computers.

The new DirectX version is 26.21.14.3136 dated 02July 2019.

So I am thinking that either my previous DirectX was corrupted some how or the new version is some kind of improvement.  I never thought to look at DirectX as an issue related to performance. Perhaps that has something to do with your issue.  My problems started with P3D 4.4 and continued with 4.5.

Anyone have any insights on this?  I posted on the P3D forum but no reponses there.

 

I was not aware about a DirectX update, but for sure I will install this if it is not automatically installed like on your rig. Thanks for the heads up!

Thank you for reply!

My PSU is less than 2 years old and it has 5 year warranty.

I do not use nVidia inspector.

I will try with "force migration" option because it was making wonders when I was having scenery issues in the past.
