Can I run Direct3D12 on my system?
Without buying 3DMark (cheapest is Advanced Edition at $24.95), you won't get the DX12 call overhead comparison test. It's also a massive download and I really just want to find out if I could run DX12 on my system!
Essentially, I wanted a Direct3D12 test / sample app that has been compiled into an executable that I could just run. Google didn't turn up anything so I decided it's easier if I compiled one myself from the SharpDX 3.0.0 alpha 2 Direct3D12 Hello World example.
So here it is.
Dx12Test requires .NET Framework 4.5. You can give it a parameter from command line to pick which adapter to initialize (0=primary (default), 1=secondary...). If your GPU doesn't support DX12, you'll get a cryptic (it's just saying it's failed to initialize DX12) error message upon starting up.
