Since 17.10.x Rainbow Six Siege is crashing frequently with my RX570.
Tried every driver release from 17.10.x onwards, but it has not improved.
Also tried complete driver re-install (without and with DDU, also AMD removal tool).
Setting the in-game graphics setting LOD to low reduces the crashes, but they're still happening from time to time when explosives or complex interactions take place.
Currently, im running WIN7-64, Adrenalin 18.2.1
