So I've been noticing a bit of framerate issues like a lot of other people since Duviri. However, I just found out one of the main issues that tanks it for me. If I go to Drifters camp, my framerate is a stable 60fps like it always is in the game, but when I stand infront of that small waterfall in the camp that has a lot of splashing water, it tanks to 30fps. I turn around, and it goes back to 60fps.
I also have framerate issues in the Plains of Eidolon since Duviri, but I can't seem to find out what causes it there. It's also during combat there that the framerate is all over the place.
I've already optimized the download cache, and none of the graphical options seem to fix this. I have a 3070 with 32GB memory. My drivers are also all up to date. I've also had the game engine on advanced since it was introduced, so that didn't change.
