Failure to load ANY d3d9.dll falls through

[mirh]

err:   d3d9.dll loading failed: 126

Long story short I downloaded an rtx-remix debug build, and eventually I figured it wasn't working because I was missing the bunch of MSVC debug libraries needed by dxvk's d3d9 and usd_ms dlls.
But this took me longer to figure out than I'd have liked because the "Direct3D is not available due to an unknown error" dialog the game was throwing at me made me shift my attention to some whatever stupid specific incompatibility of its.

Not saying you should go the whole hog and plus with diagnosing, but something this dead fundamental should be given more notability.
