Decal: pool_water02 lag fest...

Decal: pool_water02

If I place about 15 of these on my map. My game's framerate drops to about 0.6-0.9 and you can figure out the rest of it...

Anyone got any clues to why this happens? I can have rain, fog (25)particles in a small area and my framerate is fine (10 lowest < 25 highest).

Edit: Well... I messed around with some of the stuff more. I had a Plane with a water texture. When I changed its texture to a different water texture, changed it back, saved and went back to Amensia (windowed) to do a reload map. The lag went away and hasn't bothered me for a bit now. Ya, weird. I didn't even reload the map and the lag problem dissapeared.
