I tried Witcher 3 with installed Radeon Adrenalin Software 2019 (out today). That version is 18.12.2. But the fps reduced a lot, about 20-25 fps. Then I decided to use again previous version (18.11.2) and the fps went normal again (high quality 1080p average 105 fps). My gaming machine is Predator Helios 500 PH517-61 (ryzen 7 2700, radeon rx vega 56). Does anyone have same experience (reduced fps), especially using same Predator Helios 500 ? Thanks.
