I've been very impressed with how my PC has been handling the Witcher 3 since I started playing it again. Everything is on Ultra and I've been able to keep hairworks on. I'd heard that it was best to turn it off to get a good 60fps but its been managing just fine.
Its actually really nice playing through again having already completed the main story when it first came out. Last time I was so invested in Ciri's story that I probably skipped a load of side quests because I always wanted to get to the next main quest but this time I'm just allowing myself to take in everything it has to offer.
