Weird issue with blurry renders

Hi! I'm facing a weird problem with blurry renders, and I would appreciate some help...

As you guys can see in the images below, my close-up renders look well enough. However, when I try to do a full body render (in the same scene, with the same lighting, same camera, etc.) the image ends up terribly blurry.

This started when I bought a new video card (RTX 2060). Before, I could do this kind of render with no issues. Also, it seems to happen only when I make renders without background. 

Does anyone have any idea about what's going on? 

Thanks!

    Are you sure you don't have Depth of Field on for the camera?

    If you use the default render settings, your pixel filter will be set to Gaussian, and I find that leads to abysmally blurry renders.  Try setting to Mitchell with a lower pixel filter radius (0.95 or so) and see if that's better.  (Why would anyone think that something called "gaussian" would be anything other than blurry, and why would anyone make that the default?)

    Year, I'm sure it's off :(

    I tried Mitchell. Same result. Full body render still looks terrible. After reading some old topics, I tried activing "Post Denoiser Available" and "Post Denoiser Enable" and it seems to have solved the issue. I still don't know why it happened, though, since I have never had this problem with my old video card that was a lot weaker.

    In case someone has the same problem in the future, I solved the issue by unchecking "allow CPU fallback" option in the advanced tab in render settings.

    EDIT: No, it seems I still need "Post Denoiser" to make it work.
