DX12 commandlist Reset

Developer Tools Nsight Aftermath SDK

Hi,

My application crashes on call m_pCommandList->Reset(m_pCurrentAllocator, nullptr) when GFSDK_Aftermath_FeatureFlags_EnableMarkers is enable.

Is there a known workaround ?

Thanks

Regards,

Laurent

Hello,
Thank you for reporting your issue. I’m checking with the engineering team to help provide you with a recommendation on resolving this issue.

Hello,
Please confirm which Aftermath version and driver version you are using. The other question is are you calling GFSDK_Aftermath_DX12_CreateContextHandle() on the command list before you call reset on it? Please note you can get the latest Nsight Aftermath SDK from here Nsight Aftermath SDK | NVIDIA Developer.

Hello,

Yes, I’m calling GFSDK_Aftermath_DX12_CreateContextHandle. Note the application crashes before any GFSDK_Aftermath_SetEventMarker call.

As you can see, I’m using open source Diligent Engine you can find there:

My configuration is attached.
I’m using Aftermath dll version is 2.8.0.0.

Hello,
I understand you are working with our DevRel and DevTech engineers within Nvidia. Let me know if that is the case now. They should be taking the discussion from here.
