Have the same problems. I am using a Ryzen 5800x /rx 6700xt Nitro and 32gb of ram. Direct x 11 is my main issues atm. At first i thought i fix the damn thing when i did not OC my GPU. I think a month after it came back sigh. Dunno if the FF14 game does not like AMD products. I really need a fix for this before End walker comes out
