Moderators, please move if necessary. I am currently developing a rather large FPS (slightly out-of-date topic), and am almost ready for a third alpha. I have, however, hit a small coding problem on one of my newer levels with FPS. Simply put, it's a large terrain which uses the ATS package and other effects, as well as some small buildings. Unfortunately, my FPS always dips when I look out towards the majority of the level, and then becomes stable again when I look away. This drop is not too severe, but enough so to make me nervous. I'm tried everything, from changing the tree bill boarding distance to tweaking the fog settings, but no avail. Does anyone have any idea of something I can do to keep a stable FPS?
