HBAO+ in Witcher 3 Next-Gen looks worse than in Witcher 3 2015 as a black aura appeared around the objects, especially noticeable in shaded areas or in cloudy weather. If you approach the wall, a strong black halo will appear around Geralt, which should not be there, or if you look from above to the side, then a black halo will also appear at Geralt's feet. In Witcher 3 2015, HBAO+ worked fine, without artifacts, and looked awesome.
