I tried to autorun SFX in a room for when you enter it, but that causes copious amounts of lag. I know it's the SFX because when I removed it from the scene it continued running at the normal framerate. What's another way to play the SFX in an area without lag? Edit: Sorry, I didn't mean autorun. I set it to run parallel. Edit Edit: I shouldn't have posted to the fourms so hastily I'm sorry. I solved the problem like a big dummy. If you want ambient sounds to play in the background and run parallel in an area, you HAVE to put it in the BGS folder, and not as a normal sound effect. I'm not sure why, but it lags the game a bunch.
