How I fixed DXGI error hung errors in P3DV5. AMD Graphics.

Recommended Posts

Hi all,

I wanted to share with you how I got rid of my DXGI hung errors in P3DV5. 

I'm using Win 10 Pro 1909. Amd Radeon VII with latest driver 20.5.1.

I highly suggest you back up any files before making any changes!!!

In the root p3d folder there are some direct x dll files as below:

lHaWS66.jpg

 

Some in the D3D12onWin7 folder, and some in the root folder. 

Assuming you are using 64 bit OS, goto C:\Windows\SysWOW64. 

In that folder there are a lot of dll's some of them are the same as the ones in the P3D root folder. 

So basically copy the matching dll's from C:\Windows\SysWOW64 into your root P3D folder and the D3D12onWin7 folder. Overwrite when asked. You are just replacing files that are there, not adding anything new.

That's it. 

Test P3D and see how you go. I have been using this for a couple of weeks and I have not had a single DXGI hung error since doing this. 

I have not tested this with the view change CTD which only affects a few aircraft, for AMD users. I will test that this evening possibly. 

NVIDIA users please feel free to try, if you are plagued with DXGI errors. 

 

Another thing to bear in mind, you may not have the same files in folder as me, because I accidentally copied a couple of extra ones in there! Just replace the files in your folders! 

 

Thank you. 

Bully.

This is essentially replacing the DirectX 12 dll that shipped with P3Dv5 with the ones shipped with Windows. Wonder what side effects are there.

I have been using this a couple of weeks now, and I have not noticed any side effects. 

What I have noticed though, is I can have long flights 4+ hrs now with zero crashes since doing this. 

 

I have just tested the view change CTD with the A2A cessna 172 which  was causing me to crash on view change before. Now I am able to change views no problem.

The dlls in that folder are all 32 bit. P3D5 won't call them and probably loads the ones from:

C:\wimdows\system32

Which are the 64 bit versions.

Can we get some more detail on exactly which files and where to put them. No joy for me on the view change CTD

*edit* it did not work for me on a vega64, I still have the hung error on the default flight

 

from C:\windows\sysWOW64 copy the following files:

 

d3d11on12.dll

D3D12.dll

D3DCompiler_43.dll

D3DCompiler_47.dll

d3dcsx_42.dll

d3dcsx_43.dll

D3DX9_43.dll

d3ddx11_43.dll

DXCore.dll

dxilconv.dll

 

to your main p3d directory and to p3d\D3D12onWin7

sorry if I beat the same dead horse over and over again...if you have a trueglass plane (Maddog, QW787, Aerosoft Airbus....)

disable trueglass.dll in the gauges folder by adding .off to the filename. Since I did, no more crashes and yes somehow it crashed also if I did not use a "trueglass" plane when the trueglass.dll was in the gauge folder...strange.

I have found it's not totally True glass or Bathymetry. Something internal or addon I believe.

If it were me, the next step would be to remove any overclock on the GPU (including any factory O/C) do a clean reinstall of the video driver, and clear my shader cache before running P3D again.
