Hello,

I need help with my shader, for some reason it doesn't work on Intel's and AMD's integrated gpu.

to make my shader I use the default Monogame template.

Vertex Shader:

VSOutputPixelLightingTx VSBasicPixelLightingTx(VSInputNmTx vin) {
	VSOutputPixelLightingTx vout;

	CommonVSOutputPixelLighting cout = ComputeCommonVSOutputPixelLighting(vin.Position, vin.Normal, vin.Tangent, vin.Binormal);
	SetCommonVSOutputParamsPixelLighting;

	vout.Diffuse = float4(1, 1, 1, DiffuseColor.a);
	vout.TexCoord = vin.TexCoord;

	return vout;
}

Pixel Shader:

float4 PSBasicPixelLightingTx(
	float4 PositionPS : SV_Position,
	float2 TexCoord   : TEXCOORD0,
	float4 PositionWS : TEXCOORD1,
	float3 NormalWS   : TEXCOORD2,
	float3 TangentWS  : TEXCOORD3,
	float3 BinormalWS : TEXCOORD4,
	float4 Diffuse    : COLOR0
	) : SV_Target0 {

	float4 color = SAMPLE_TEXTURE(Texture, TexCoord) * Diffuse; 
	float3 eyeVector = normalize(EyePosition - PositionWS.xyz);

	clip(color.a - .001);
		
	float4 bump = SAMPLE_TEXTURE(NormalMap, TexCoord) - float4(0.5, 0.5, 0.5, 0);

	float3 bumpNormal = NormalWS + (bump.x * TangentWS + bump.y * BinormalWS);
	bumpNormal = normalize(bumpNormal);

	ColorPair lightResult = ComputeLights(eyeVector, bumpNormal, 3);

	color.rgb *= lightResult.Diffuse;

	AddSpecular(color, lightResult.Specular);
	ApplyFog(color, PositionWS.w);

	return color;
}

the VSOutputPixelLightingTx struct:

struct VSOutputPixelLightingTx {
	float4 PositionPS : SV_Position;
	float2 TexCoord   : TEXCOORD0;
	float4 PositionWS : TEXCOORD1;
	float3 NormalWS   : TEXCOORD2;
	float3 TangentWS  : TEXCOORD3;
	float3 BinormalWS : TEXCOORD4;
	float4 Diffuse    : COLOR0;
};

I use vs_3_0 and ps_3_0 to compile them.

Result on Nvidia and AMD dedicated card :

Result on intel and AMD integrated chip :

Over the last two day I try every solution i can find online but were not successful.
I think I am doing something wrong...
