Brief description of the issue:
Whenever I fly in clouds my fps just tanks to like 10. Normally it runs around 30 to 55 fps even when overcast. But when I am inside a cloud (or it’s foggy) my fps just tanks. This happens especially in the outside view. I tried lowering the settings but still the same issue
