Archicad 28 Direct3D Runtime Error

[ETSaum]

Archicad 28 is constantly freezing or crashing, diving a Direct3D / graphics card error.

Archicad 27 and Archicad 26 do not have the same problem.

I've updated graphics drivers, and uninstalled / reinstalled Archicad to no avail.

I get the same error every time; sometimes, it's within seconds of opening the program. Other times, it can take several minutes. But it happens multiple times a day.

'Direct3D Runtime received a Device Removed Message  DXGI_ERROR_DEVICE_HUNG'

That's typically an issue with either the graphics card itself or the graphics card's connection the rest of the machine. However, this is the *only* program experiencing the problem, which is usually indicative of a glitch in the program or an incompatibility between the program and the graphics drivers.

These are two of the smallest projects I've ever done in Archicad, and the only two on 28 so far. Archicad 28 appears to be sending conflicting instructions to the GPU, which causes it to hang. No other programs are effected when it happens; in some instances, when it happens in one Archicad 28 file, it doesn't even impact the *other* Archicad 28 file I've got open.

I was going nuts with this problem! Thank goodness for this thread ❤️ disabling "Fade Environment" seems to be the quick fix.

Also, I have realised that the problem only appeared when I had my external screen connected and working with AC on that screen.

As long as AC is running on my laptop it seems to work just fine...
