Manual depthbuffer flip

return depth;

Replace that with

return -depth;

It seems the SSAO shader now uses the normalized buffer created by that shader in Reshade.fx instead of its own (which was the case in 1.0).

// Fullscreen Triangle Vertex Shader
void RFX_VS_PostProcess(in uint id : SV_VertexID, out float4 pos : SV_Position, out float2 texcoord : TEXCOORD)
{
	texcoord.x = (id == 2) ? 2.0 : 0.0;
	texcoord.y = (id == 1) ? -2.0 : 0.0;
	pos = float4(texcoord * float2(2.0, -2.0) + float2(-1.0, 1.0), 0.0, 1.0);
}

#if RFX_InitialStorage
float4 RFX_PS_StoreColor(float4 vpos : SV_Position, float2 texcoord : TEXCOORD) : SV_Target
{
	return tex2D(RFX_backbufferColor, texcoord);
}
#endif
#if RFX_DepthBufferCalc

Anything I might miss? Is it possible that it just might be the game or should it theoretically work with every flipped depth buffer? It does look like it flips normals, not the 2D ssao output itself.

Edit: Ok, the solution to my problem rather seems to be this . After changing reshade.fx it gives out an error message, though, so I must've made some mistakes. Does that solution work with 1.1.0 at all? If yes, could anyone give more precise insturctions for a coding noob like me which lines to add and which to delete, if any?

float2 source = float2(texcoord.x, 1.0-texcoord.y);
float depth = tex2D(RFX_depthColor, source).x;

Janson wrote: Another thing, the linearization of the depthbuffer/value, is this a method that has to be done always a certain way or is it possible to do it several different ways? What I'm trying to get at, some games that seemingly don't show information inside the depthbuffer visualisation, is it possible that they have to be approached individually/differently to get to that information?
