Same here. rx 6700xt/ryzen 5 5600x. Every game runs fine other than D2. Definitely not heat or OC related as everything is stock. Before frame drops were intermittent and a restart or changing Window/Full screen mode sometimes helped. But this weeks Override especially drops to 40 fps no matter what settings I choose. Clearly there's a bug in the code Bungie. Get the Fireteam together and splice that sheet guys ;)
