I'm wondering if anyone can give some tips of where to start looking.
When I got my new laptop, I had backed up my old AC data, and copied it across to the new laptop. Being an 11th Gen i9 with an RTX3600 I started looking at the good graphics, I had SOL but with the new machine went to Pure. I went a step further and decided to try out the reshade f1 thing and it killed the FPS, going from consistently over 100 to struggling to get above 30. I uninstalled the reshade software, but ever since my FPS are lower than they had been, but still smooth enough to drive, but the biggest issue is that I get an intermittent black flickering in the sky and some other textures, at random. I've tried reinstalling & resetting pure, reinstalled the high res sky etc but it stays, and nothing I do increases the FPS back to where it used to be, over 100.
Im not sure where to start to get back to how it was before reshade. I want to avoid a fresh install, as many mods I have installed put files all over the place, like the RSS mods as an example. Im fearful that a fresh install will break some of the tracks and mods. I dont think the tracks are as much of an issue, but nearly 1100 cars, its going to be a massive task to try finding all the mod install files again.
