    Problem with shaders Compilation

    kiwi

      I yesterday bought Prepar3D V3 when it was released and I installed it without a problem however as yet have not been able to get past the scenario screen.

      I put a message in their forums and the tech is saying that the error message is something to do with Directx 10 .

       

      This is the problem error message below

       

      I load V3 as far as the scenario window and then it crashes when I try to load the airport.

      I have only got default V3 no addons whatsoever. Running windows 7 ultimate 64-bit and these are the two error logs I have recieved.

       

      [error.0]

      error=Shader compilation failed - Error Msg: C:\Lockheed Martin\Prepar3D v3\ShadersHLSL\ParticleCS.fx(325,13): error X3660: cs_4_0 does not support interlocked operations

       

      [error.1]

      error=Shader cache failed to compile or create shader. source-file: C:\Lockheed Martin\Prepar3D v3\ShadersHLSL\ParticleCS.fx cache-file: C:\Users\Kiwi\AppData\Local\Lockheed Martin\Prepar3D v3\Shaders\v3010_sm100_ParticleCS.fx_CSSimulate_0000000007000000_0050000000000001.cso

       

       

      This is the reply I got from Lockheed martin  as well as trying the V14.12  driver which some people are saying is working however it is not working for me.

      Geoff,

       

      The "sm100" in the shader cache file name indicates a DirectX10.0 shader compile. Either your card does not support shader model 5.0 (DirectX 11.0), or Prepar3D is attempting to run on a DirectX10 anboard graphics card. Are you getting the warning about falling back to DirectX10?

       

      EDIT. Just read your other post. I see that your card supports 11.2. It's odd that it is trying to compile a 10.0 shader as that only happens if the card reports that it does not support the 11.0 feature set.
