I’ve been using AMD GPUs with FS 2020 from the first day of its release. I started with a Sapphire RX590, then to a Sapphire RX6700TX, and now a Sapphire RX7900XT. I haven’t had any unsolvable issues with the drivers so far.
The RX7900XT has impressed the heck out of me. At the moment, I can’t think of a better GPU for the price.
