crash on start

[NemuiSen]

when I run any example or create a new project the application crashes and the console prints this:

Can you try against master? It upgrades wgpu, just to rule out if that's the issue or not, otherwise best guess is there is a fault in your driver, i would check if you have an update. It failed acquiring a command pool in directx, I don't think that's possible without running out of video memory or a bad driver.

[NemuiSen]

update everything and the problem still continues, I also tried to compile an example with the GFX-RS library with directx 12 and the same problem appears, the only exception is the "compute" example that only prints what is entered.
Another thing to mention is that other programs or games that use directx 12 like Nuclear Throne work fine.

[hecrj]

@NemuiSen In that case, we should report the issue to the gfx-rs maintainers.

[nathaniel-daniel]

Looks like it's already tracked by gfx-rs/wgpu#1382. At the very least, it seems like the same underlying error.

[NemuiSen]

Well, it turns out that the problem was the graphics drivers but for having the latest version of the drivers since it turns out that in the 3rd generation intel processors directx12 support was removed for security reasons. Sorry for the inconvenience.
