SigilFey, greetings!
As I posted before, I have installed fully fresh (which means there wasn't any previous settings or any related files on the computer) and clean (without any mods) game on clean Windows. And yes, I've even started a new game (bc I forgot were I ended up my previous 1.52 game progress ). However, I have found 1.52 version, installed it alongside 1.6 (in a different location ofc) and it runs smoothly as it was when I played it back in May 2022. Both in benchmark and actual gameplay 1.52 shows >30%!!! better low, average and max framerate (I linked screenshot to one of my previous posts, sorry for russian language on it). Settings are the same. So I think the problem is not between the game files and my system config. And yes, I've tried to use different GPU drivers, and last ones, 516.94, shows the best possible results, both in 1.52, and in 1.6. Cleared settings, cleared shaders caсhe. Tried both Steam ang Gog versions. Nothing changes.
I have also noticed, that in 1.52 version changing from Ultra RT, to Medium or Psycho gives a noticeable difference in framerate - up to 10 fps, however in 1.6 difference may be barely noticeable - about 1-2 fps.
I think I'll no longer be trying to solve this, for now I'm pretty sure that it's a current patch problem and I will come back to it when the hotfix will be released. I searched for YouTube comments under performance comparison videos, reddit, steam and other discussions with these framerate issues after the patch 1.6, and there are lots of similar complaints, even on top configs with 3090TI and etc. Nevertheless, there are people who notice better or same framerate.
I also sent my specs, dxdiag file, all information about an issue and benchmarks comparison to CDPR Support. We'll see.
Huge thanks for replays and help anyway!
