Do saves from patch 1.5 work on patch 1.2? (Cyberpunk 2077)

I played a little on patch 1.5, I didn’t like it because I initially knew that the vidyuha would not pull, but I knew how to squeeze the maximum fps out of the game, but I was disappointed because after the release of patch 1.5, most programs stopped working, as I read this because the developers abandoned the majority modders to find new modders, new mods, etc. (though probably just stuffing). In general, I watched the method from the king jra video, but the video was old and at that time there was only patch 1.2, and now the question is brewing, what to do if you have already gone through not a small part of the game, but you want to roll back to the old version of the patch to increase fps. Is it possible to load a save from a new patch into an old one?
