Optical flow (gpu) output resolution

this report is regarding the optical flow gpu solver

it seems the output texture size is constant at 609x405 px, disregarding input size
am i doing something wrong or is this an error ?

the tfx takes res from first texture pin, if there is nothing there is default size pin in shader hidden.

i see
so its an issue regarding what is declared inside the shader
i do not speak hlsl, but, just for the sake of it, the first pin should be no different from the ActualTex pin

it can be whatever but it gonna get res from it
