Scaling and Offsetting Shaders

Is there a way to scale/offset a shader or do I have to figure out how .fx files work and start adding magic numbers? I'm using PCSX2 to play shadow of the colossus and wanted to add mxao, but it seems the game's depth buffer uses a lower resolution than the game's output resolution. Pic 1 shows the game running at 1080p and Pic 2 shows the mxao output.

The commands RESHADE_DEPTH_INPUT_X_SCALE , RESHADE_DEPTH_INPUT_Y_SCALE and RESHADE_DEPTH_INPUT_X_OFFSET, RESHADE_DEPTH_INPUT_Y_OFFSET sadly only seem to work for the DisplayDepth shader.

MXAO supports those, but you need the latest version of MXAO, which is in the qUINT package (qUINT_MXAO.fx).

Thanks for the reply.
I just tried the updated version of MXAO, but now it fails to detect any depth (debug view stays white/show normals works and shows that the scaling worked).
Any advice on troubleshooting this?
