Ever since upgrading from a Vega64 to the 6800XT Black I have had issues in MSFS2020. I keep getting AMD Driver Timeout Errors and then a CTD. I have tried various drivers with no luck getting rid of the issue. And any driver released in April and May will not work at all as they just turn MSFS into a slide show, including the one released today, May 17. I am starting to regret buying the 6800XT as the Vega worked perfectly in MSFS.
Rest of system is a Ryzen 5800x on an Asus x570 Tuf Gaming, 32gig PC3600, a 1gig nVme for o/s (Win10 64bit)
