I’m also having the same issues. The main menu sometimes drops me to 10 frames. I have to restart the program again and all of a sudden the laggy low frames are gone and i’m back up to 80 frames.
Then when I launch a flight, sometimes my destination airport caps me at 10 frames. Sometimes my arrival landing airport caps me at 10 frames consistently for 10 minutes. It feels unplayable. FYI, I own a 2080ti RTX (3 fans). I run on high 1080p and should be getting smooth fps yet i’m not. The developer graph tells me the GPU handler is whats capping me. This last update created this problem.
My biggest worry is that Asobo doesn’t recognize this issue. I haven’t seen a lot of posts about this and the people here in this post including myself are seldom. I just hope our issue reaches the Asobo team. If you all can, I encourage you to send tickets to zendesk or try to get this post/like up so devs can see it.
