I have the same issue now as well. I am running an MSI RTX 2080 Trio and had no issues back in June. Stop playing for a while then came back the other night and nothing but freezes. Like the others, DCS is the only game that does this. I play other graphic intensive games set on Ultra and absolutely no issues so it is DCS related. As I said, I was playing this game over the summer with the same GPU and no problems so whatever the problem is, it seems to be something that has changed in DCS.
