So RT just stopped working on my saved files but does on new game for pc?

I can’t find much online about this but ray tracing worked my whole playthrough then halfway through I get an odd glitch that basically removed shadows. I restated game it worked normally but now when I enable ray tracing it will not work. It will say it’s enabled but I’ve loaded 4 different saves from my playthrough and all of them have same fps whether it’s on high or off.with much higher fps then I had when it actually worked. Starting new game there’s a 30fps difference so it works there oddly enough. It’s like my save is just bugged now.. all of them that are connected to my main playthrough. Does anyone have any clue what’s happening and if I can fix this? I can’t even find the games save location to check saves but config does say it’s on.. not sure if doing ddu and recompiling shaders will help since it seems so tied to my save..very frustrating. Rtx 3080 btw windows 11 and im not on driver 591.74.
