DX11 windows8.1 disables part of DirectX control panel?

Recommended Posts

Hi,

I have to maintain some old D3D9 code and I have to use a windows8.1 machine to do it, everything compiles and runs, but I need the debug runtime activating to search down some issues. However, it's been greyed out - eek!

I did find some posts referring to a fix for this: "Using regedit, go to key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Direct3D. The "Trusted Installer" has ownership of this key. Change ownership to Administrators, then grant "Full Access" to the Administrators. Now run the DX Control Panel (as admin, of course). Now the changes should be saved."

 

Problem is I can't find Direct3D in the registry? I've got DirectDraw/Input/Music/Play/Show/X/XSDK, but no Direct3D.

 

Anybody got any ideas how to activate the debug runtime? I know the obvious ones are either go back to win7 or upgrade all the code DX11, but sadly neither of those options are practical.

 

 

thanks...

LOL... thanks for citing me.

Is this new in 8.1; I mean, was the key present in Windows 8.0?

I don't know, never had win8.0, I've been hanging onto win7 as long as I can, but everything just got updated straight to 8.1 at the office so I'm a bit stuffed.

Yes, there is a Direct3D key in there - woo!. However, I can't follow the original fix, as permissions work differently in win8.1 than in win7 so not really sure what to do.

Debug runtime of the "old legacy" DirectX SDK (2010 and prior)  don't work on Windows 8/8.1 and even on windows 7 SP1 with Platform update as far as I know. This is why PIX don't works on those platforms.

 

If you want debug dx9 code, you need a machine With Windows 7 (without the platform update) or a previous OS.

The fix I posted above enables the use of debug runtimes on Windows 7 even after SP1.

 

The platform update was the breaking change, though.  That's the one in kb2670838 where the D3D11.1 components came in and wrecked everything.

Thanks for all the help, I did manage to take ownership of the registry keys (finally), but it doesn't make any difference. This does seem a bit of a heavy handed move by MS, not sure what a "checked" version of win8.1 is or where to get it. A bit of text output doesn't seem a lot to ask for those of us forced to maintain old code (surely hundreds?).

I think that the only thing we need from the "checked" version is the d3d9.dll & d3d9d.dll. (I'm just speculating, might be more that is needed)

I made a test and copied the d3d9d.dll from my Win7 machine to C:\Windows\SysWOW64\ on my Win8 machine. Obviously is does not work, but one can note that the Direct3D 9 control panel is no longer grayed out. It would be nice to know if there is a d3d9d.dll out there somewhere for Windows 8

The only way to get the debug version of Direct3D 9 for Windows 8 is to install a 'checked' version of the OS.

 

 

"checked" version aka Debug Symbol installed? Here are the installers: http://msdn.microsoft.com/en-us/windows/hardware/gg463028.aspx

The ISO with Symbols is also available on MSDN and Dreamspark Premium accounts..

      I have a gaming framework with an renderer interface. Those support DX8, DX9 and latest, DX11. Both DX8 and DX9 use fixed function pipeline, while DX11 obviously uses shaders. I've got most of the parts working fine, as in I can switch renderers and notice almost no difference. The most advanced features are 2 directional lights with a single texture  
      My last problem is lighting; albeit there's documentation on the D3D lighting model I still can't get the behaviour right. My mistake shows most prominently in the dark side opposite the lights. I'm pretty sure the ambient calculation is off, but that one's supposed to be the most simple one and should be hard to get wrong.
      Interestingly I've been searching high and low, and have yet to find a resource that shows how to build a HLSL shader where diffuse, ambient and specular are used together with material properties. I've got various shaders for all the variations I'm supporting. I stepped through the shader with the graphics debugger, but the calculation seems to do what I want. I'm just not sure the formula is correct.
      This one should suffice though, it's doing two directional lights, texture modulated with vertex color and a normal. Maybe someone can spot one (or more mistakes). And yes, this is in the vertex shader and I'm aware lighting will be as "bad" as in fixed function; that's my goal currently.
      // A constant buffer that stores the three basic column-major matrices for composing geometry. cbuffer ModelViewProjectionConstantBuffer : register(b0) { matrix model; matrix view; matrix projection; matrix ortho2d; }; struct DirectionLight { float3 Direction; float PaddingL1; float4 Ambient; float4 Diffuse; float4 Specular; }; cbuffer LightsConstantBuffer : register( b1 ) { float4 Ambient; float3 EyePos; float PaddingLC1; DirectionLight Light[8]; }; struct Material { float4 MaterialEmissive; float4 MaterialAmbient; float4 MaterialDiffuse; float4 MaterialSpecular; float MaterialSpecularPower; float3 MaterialPadding; }; cbuffer MaterialConstantBuffer : register( b2 ) { Material _Material; }; // Per-vertex data used as input to the vertex shader. struct VertexShaderInput { float3 pos : POSITION; float3 normal : NORMAL; float4 color : COLOR0; float2 tex : TEXCOORD0; }; // Per-pixel color data passed through the pixel shader. struct PixelShaderInput { float4 pos : SV_POSITION; float2 tex : TEXCOORD0; float4 color : COLOR0; }; // Simple shader to do vertex processing on the GPU. PixelShaderInput main(VertexShaderInput input) { PixelShaderInput output; float4 pos = float4( input.pos, 1.0f ); // Transform the vertex position into projected space. pos = mul(pos, model); pos = mul(pos, view); pos = mul(pos, projection); output.pos = pos; // pass texture coords output.tex = input.tex; // Calculate the normal vector against the world matrix only. //set required lighting vectors for interpolation float3 normal = mul( input.normal, ( float3x3 )model ); normal = normalize( normal ); float4 ambientEffect = Ambient; float4 diffuseEffect = float4( 0, 0, 0, 0 ); float4 specularEffect = float4( 0, 0, 0, 0 ); for ( int i = 0; i < 2; ++i ) { // Invert the light direction for calculations. float3 lightDir = -Light[i].Direction; float lightFactor = max( dot( lightDir, input.normal ), 0 ); ambientEffect += Light[i].Ambient * _Material.MaterialAmbient; diffuseEffect += saturate( Light[i].Diffuse * dot( normal, lightDir ) );// * _Material.MaterialDiffuse; //specularEffect += Light[i].Specular * dot( normal, halfangletolight ) * _Material.MaterialSpecularPower; } specularEffect *= _Material.MaterialSpecular; //ambientEffect.w = 1.0; ambientEffect = normalize( ambientEffect ); /* Ambient effect: (L1.ambient + L2.ambient) * object ambient color Diffuse effect: (L1.diffuse * Dot(VertexNormal, Light1.Direction) + L2.diffuse * Dot(VertexNormal, Light2.Direction)) * object diffuse color Specular effect: (L1.specular * Dot(VertexNormal, HalfAngleToLight1) * Object specular reflection power + L2.specular * Dot(VertexNormal, HalfAngleToLight2) * Object specular reflection power ) * object specular color Resulting color = Ambient effect + diffuse effect + specular effect*/ float4 totalFactor = ambientEffect + diffuseEffect + specularEffect; totalFactor.w = 1.0; output.color = input.color * totalFactor; return output; }   Edit: This message editor is driving me nuts (Arrrr!) - I don't write code in Word.

      Hey folks. So I'm having this problem in which if my camera is close to a surface, the SSAO pass suddenly spikes up to around taking 16 milliseconds.
      When still looking towards the same surface, but less close. The framerate resolves itself and becomes regular again.
      This happens with ANY surface of my model, I am a bit clueless in regards to what could cause this. Any ideas?
      In attached image: y axis is time in ms, x axis is current frame. The dips in SSAO milliseconds are when I moved away from the surface, the peaks happen when I am very close to the surface.

       
      Edit: So I've done some more in-depth profiling with Nvidia nsight. So these are the facts from my results
      Count of command buffers goes from 4 (far away from surface) to ~20(close to surface).
      The command buffer duration in % goes from around ~30% to ~99%
      Sometimes the CPU duration takes up to 0.03 to 0.016 milliseconds per frame while comparatively usually it takes around 0.002 milliseconds.
      I am using a vertex shader which generates my full-screen quad and afterwards I do my SSAO calculations in my pixel shader, could this be a GPU driver bug? I'm a bit lost myself. It seems there could be a CPU/GPU resource stall. But why would the amount of command buffers be variable depending on distance from a surface?
       
       
      Edit n2: Any resolution above 720p starts to have this issue, and I am fairly certain my SSAO is not that performance heavy it would crap itself at a bit higher resolutions.

      In DirectX 11 we have a 24 bit integer depth + 8bit stencil format for depth-stencil resources ( DXGI_FORMAT_D24_UNORM_S8_UINT ). However, in an AMD GPU documentation for consoles I have seen they mentioned, that internally this format is implemented as a 64 bit resource with 32 bits for depth (but just truncated for 24 bits) and 32 bits for stencil (truncated to 8 bits). AMD recommends using a 32 bit floating point depth buffer instead with 8 bit stencil which is this format: DXGI_FORMAT_D32_FLOAT_S8X24_UINT.
      Does anyone know why this is? What is the usual way of doing this, just follow the recommendation and use a 64 bit depthstencil? Are there performance considerations or is it just recommended to not waste memory? What about Nvidia and Intel, is using a 24 bit depthbuffer relevant on their hardware?
      Cheers!

      Hi! I am trying to implement simple SSAO postprocess. The main source of my knowledge on this topic is that awesome tutorial.
      But unfortunately something doesn't work... And after a few long hours I need some help. Here is my hlsl shader:
      float3 randVec = _noise * 2.0f - 1.0f; // noise: vec: {[0;1], [0;1], 0} float3 tangent = normalize(randVec - normalVS * dot(randVec, normalVS)); float3 bitangent = cross(tangent, normalVS); float3x3 TBN = float3x3(tangent, bitangent, normalVS); float occlusion = 0.0; for (int i = 0; i < kernelSize; ++i) { float3 samplePos = samples[i].xyz; // samples: {[-1;1], [-1;1], [0;1]} samplePos = mul(samplePos, TBN); samplePos = positionVS.xyz + samplePos * ssaoRadius; float4 offset = float4(samplePos, 1.0f); offset = mul(offset, projectionMatrix); offset.xy /= offset.w; offset.y = -offset.y; offset.xy = offset.xy * 0.5f + 0.5f; float sampleDepth = tex_4.Sample(textureSampler, offset.xy).a; sampleDepth = vsPosFromDepth(sampleDepth, offset.xy).z; const float threshold = 0.025f; float rangeCheck = abs(positionVS.z - sampleDepth) < ssaoRadius ? 1.0 : 0.0; occlusion += (sampleDepth <= samplePos.z + threshold ? 1.0 : 0.0) * rangeCheck; } occlusion = saturate(1 - (occlusion / kernelSize)); And current result: http://imgur.com/UX2X1fc
      I will really appreciate for any advice!
