'PBR shading only works in the corner of the window. DirectX 11

As the title implies i have problems with DirectX 11 shading. The problem is shown in the picture below. enter image description here

I have tried drawing it to the framebuffer, Change the math order in the shader, resize the BRDF to the window. But nothing seems to work. I generate the BRDF with computeshader, same with the irradience map and cube map. I use a Equirectangular image to get the cube data.

any sugestion would help, thanks!
