Bizarre problem with menus and framerate.

[KnowHope]

I haven't seen this specific issue anywhere, so I'm making a thread.

It seems like menus are screwing up my framerate. At least, that's how it looks.

Upon starting the game, I can be running at 60FPS, but when I go into any menu (pause, journals, etc...) and then back to the game, my FPS drops to 30 and won't return to 60 unless I wait for long enough (and sometimes it doesn't appear to correct itself at all). But it'll be fine when in a menu again. I've tried changing "LimitFPS" to false, but coming out of menus still causes the FPS to stick at 30.

It wouldn't have anything to do with my specs; my PC is more than capable.

Any ideas? Anyone getting the same thing?
