--- Comment #3 from Aaron Franke arnfranke@yahoo.com --- I apologize for that. I think it would be a good idea to rename that category to `directx-d3dx11-lib` or something to clarify that, as I didn't know.
Also, yes, missing d3d10 effects are probably a bigger issue, d3d11 is likely non-vital calls considering Steam Big Picture's system requirements list DX10. Though this bug is still valid because Steam Big Picture does use these calls.
