Device removal exception

[Canvas02]

I don't know if this is a bug or is something wrong on my side but, when trying to run the wgpu examples I get this:

Using Intel(R) HD Graphics 4600 (Dx12)
[2023-03-19T15:27:10Z ERROR wgpu_hal::auxil::dxgi::exception] ID3D12Device::RemoveDevice: Device removal has been triggered for the following reason (DXGI_ERROR_DEVICE_HUNG: The Device took an unreasonable amount of time to execute its commands, or the hardware crashed/hung. As a result, the TDR (Timeout Detection and Recovery) mechanism has been triggered. The current Device Context was executing commands when the hang occurred. The application may want to respawn and fallback to less aggressive use of the display hardware). [ EXECUTION ERROR #232: DEVICE_REMOVAL_PROCESS_AT_FAULT]

Additionally while trying to run the iced examples (while using the wgpu backend) I get this:

thread 'main' panicked at 'wgpu error: Validation Error

Caused by:
    In Device::create_buffer
      note: label = `(wgpu internal) StagingBelt staging buffer`
    parent device is lost

I am running windows 10 (OS Build 19045.2728) with a duel gpu setup, an Integrated (Intel) gpu and a dedicated (Nvidia) gpu

Is there any way I can fix this?

Is there any way I can force wpgu to use the dedicated gpu

I already have the "use high performance processor" in the nvidia cotrol panel

You can set PowerPreference to HighPerformance when calling request_adapter.

[Canvas02]

What if I am using a library like iced, is there something like an environment variable where I can force it to use the high performance adapter?

[xiaopengli89]

I don't think so.

What about these: https://github.com/gfx-rs/wgpu#environment-variables

Will they do the job? Or are they foe something else?

[xiaopengli89]

These env vars only works in tests or examples.

Oh ok I think I should close this issue then.

If I want to contribute an "env var overloading" feature would it get accepted or no?

Since wgpu is a lib, we shouldn't switch default behavior based on env variables. Those can be implemented by applications built on top instead.
