I wasn't sure where I should post this, but I guess it has the most to do with level design.
What I wanted to ask is that why does the lag build up in (for example) this level?
It doesn't lag at all first, but if I keep it open long enough the FPS drops from ~25-30 to ~5.
Doesn't bother me though :P I was just messing around with the editor and I knew it would cause lag.
Offtopic: FPS TEST :E
I wonder how many FPS would it take to make it (look) white (to human eye) :D
EDIT2: If you squint your eyes it becomes pretty white.
(Btw by the time I had this thread written the second level's FPS had dropped from 29-30 to ~12 too)
EDIT: Why isn't the "Show FPS" option permanent like the key settings?
EDIT3: FPS (in the second level) dropped to 0 when I left my computer for a while and had the level still open.
