Assassin’s Creed Odyssey water glitch

This glitch doesn't stop. Makes the game unplayable in or near water. Originally thought it was because of my dying mobo. Nope. Just replaced my PC, fresh Win 10 install, and verified game file integrity in Steam AMD Ryzen 5 2600X Nvidia RTX 2070 X470 ASRock Gaming K4 Steam won't refund.
