Describe the bug

The Direct3D Pixel Shaders and the Scaler will not work in Dosbox-X 0.83.23 SDL2 64bit Visual Studio Build.

Expected behavior

OpenGL and OpenGL Shaders work.

Scaler have no effect
Direct3d Pixel Shader have no effect

Steps to reproduce the behaviour

1. Start Dosbox-X
2. Pixel Shaders stored in shaders Directory
3. Select Direct3D as Output in Video Menue
4. Select D3D Pixel Shader in Video Menue

Used configuration

Output = direct3d


frameskip      = 0
aspect         = false
char9          = true
euro           = -1
doublescan     = true
scaler         = normal2x
glshader       = none
pixelshader    = none
autofit        = true
monochrome_pal = green

and 

frameskip      = 0
aspect         = false

Update: Shaders works if Doublescan is disabled, but Direct3d Pixel Shaders still don't work.

According to the source code, it uses D3DXCreateEffectCompilerFromFile function (link).
It requires d3dx9 library so I think you need to install Direct X9 runtime to work on Windows10 and 11.

// cited from ScalingEffect.cpp
// First create an effect compiler
    HRESULT hr = D3DXCreateEffectCompilerFromFile(filename, NULL, NULL, 0,
						&lpEffectCompiler, &lpErrors);

Shaders work fine on my Windows8.1 PC.
This issue is a duplicate of #2884

Hi,
ok thanks for the Info. I don´t know that it needs Directx9
