You gotta to be kidding me..
So I went back to my project with have been abandoned for months, and to my surprise it gave me error at releasing sampling states..something I dont mess with in freagging ages..
Did some inspection, nothing wrong with the samplers...than I changed the order of releasing, and released samplers before, than input layout states, and voila, the access violation came for the input layout..
Since I dont mess with any of that for ages, the only thing that changed is that I aquired a (btw super expensive holy shit) cintiq, withch works as a second monitor. So I disabled it from the nvidia panel, and voila.. no more access violation.
How do I even begin to solve this..
