I bought myself an GIGABYTE RX 5700 GAMING OC 8G, I could not start the computer without dancing with a tambourine, it rebooted itself during the game. We managed to fix the problem by changing the Gen Switch value from AUTO to Gen3(MSI B450M MORTAR) Then the game started(AC Unity) normally, but artifacts with puddles are visible in the game and later caught BSOD. Latest driver 19.10.1
Also, my monitor began to flash randomly. Before that, I had the RX 570 Nitro+, there were absolutely no problems.
