I will assume you have already tried this but just in case - Did you make sure to right-click, properties and then set it to 'read-only' this will allow any changes you have made from rolling back to their default settings etc.
I have had no issues other than what I believe may have been an unstable OC and display driver errors. If you have already done as I said above than disregard and good luck to finding a fix soon! I have only had a few freezes and CTD's but other than that it's been running well for me.
My rig for reference - i5-4670k @ 4.4ghz, EVGA 980 SC, 8gb ram.
ETA: Hairworks off, everything maxed minus shadows on high my FPS ranges around 54-60. Hair works on I get between 46-48 to low 50's, of course this depends on the area/scene. Hair-works looks good but for me personally ATM it's not worth the fps hit. The default hair that CDPR created is actually very good imo, so no problem using it for me.
Update: With the latest patch 1.04, I'm almost positive they lowered max particle amount, I would of sworn it was 3000, now it's 1000. Igni casts a bit faster and without the stutter that I experienced from time to time a few days back..
