Hello,

I wanted to compile a DX11 shader (model cs_5_0) with fxc that comes with the DirectX SDK June (2010), I need to use that SDK for the time being due to distribution problem

But the compilation terminates unexpectedly.

My CPU is i7 6500U with HD 5200, it supports shader model 5.1 and DirectX 12, I am not sure if that supports compute shader 5.0

I tried to compile the compute shader using the shader model 5.0 (fx_5_0), it compiles and didn't work as expected.

So I thought I still I need to compile that shader using compute shader model 5.0

Does my CPU support cs_5_0?

Thanks

Jack

If necessary, you can offline-compile your shaders. Meaning, you'd only need one machine that has an updated SDK to get a newer version of fxc.exe so that you can compile your shaders into a header file or cso file. And if you're only having this problem for compute shaders, you could even keep the rest of your shaders going through whatever system you have (build-time or run-time, though hopefully not run-time) and just offline compile the ones that are problematic for you.

I'm pretty sure that the root of your problem is your old version of fxc. You could also use d3dcompiler_47.dll which is included in the OS since Windows 8 to compile your shaders using the D3DCompile function. You could either do it at runtime, or using a helper utility which invokes it instead of using fxc.
