DirectX Error

[cuppajoeman]

Hi there,

I just got windows to test out the Jolt Samples, I'm compiling with msys2 using the urct profile. I followed the steps in the Build directory and everything compiled correctly and all tests pass.

When I try to run Samples.exe I get the following error:

I tried looking up this error but I haven't been able to find the cause, the computer is a lenovo thinkpad T470:

The error is:

DXGI_ERROR_DEVICE_REMOVED
0x887A0005

which is a very generic error that doesn't say much.

First thing to check is if your graphics drivers are up to date.

Next thing would be to run Samples in Debug mode and look at the debugger output (usually it traces a meaningful message because the DirectX debug layer is active in debug mode). Easiest way to get to the debugger output is to compile and run everything using Visual Studio 2022 (free to download). In MSYS2 it is probably also possible but you'll need an external tool like DebugView++ to view the debug output.

Perhaps you can also break the application when the error message triggers to get the callstack (and line number) where the problem happens.

Ok, so I was able to get some more info through the CLion IDE which gives me some easy debugging utilities. I chose to use CLion because it seems more similar to my linux experience.

It comes bundled with a toolchain, which is as follows: (if that info is useful)

Here I'm attempting to run Samples with debugging.

I managed to solve the above problem by enabling "Graphics Tools" which is an optional windows settings. To enable it you have to press the windows key, search for manage optional features, and then click add a features, and install Graphics Tools. This probably automatically happens with VS so might not have been noted down in the build guide for windows.

Now building and attempting to run Samples gives the following feedback:

[New Thread 7636.0x2ce4]
warning: Created font "Arial" with height 24 in a 512x256 surface
warning: D3D12 ERROR: ID3D12Device::CreateShaderResourceView: The Format (0x29, R32_FLOAT) is invalid when creating a View; the Resource was already created with a fully qualified Format, which is not castable (0x28, D32_FLOAT). [ STATE_CREATION ERROR #28: CREATESHADERRESOURCEVIEW_INVALIDFORMAT]

Specifically this error is eminating from this line

I believe the problem here is that on line 179 we are giving a specific format: srv_desc.Format = DXGI_FORMAT_R32_FLOAT;, and for some reason that type is not allowed, I'm not exactly sure...

[jrouwe]

I don't know why that's not allowed on your machine, on my machine that's the only value that is allowed.

You can work around this by commenting out the shadow rendering code:

[cuppajoeman]

Hey @jrouwe I just tested on the test/no-shadow branch, on this branch when I compile and run the Samples target I get everything running just without shadows.

Adding the patch for future reference before deleting the branch:
