I didn't do anything special; just used whatever were the default settings.  I'll take a look at your file later to see if I can find anything useful about the audio data.  Do you get the same behavior if you use the CodecJOrbis plug-in?  Also, do you get the same behavior for every file you convert or just this one?

Well I just converted some random mp3 I found on my pc to ogg and it didnt have a screech anywhere, so it might just be that file.

*edit: it turns out i was already using the most recent version of lwjgl but not jpct.  Upgrading JPCT from 1.21 to 1.23 actually fixed the problem.  Good job on your updates!  I did confirm that Aero was what was messing up the 1.21 jpct's windowed mode, but it looks like you fixed that.

i think the frame rate is the same when its not lagging.  It starts lagging as soon as i walk in range of the second camera which is rendering to the texture.  Like almost freezes less than 1 fps.  Im on Windows 7 64 bit and using a Radeon HD 5870.  Im not entirely sure when it started happening I used to have a sphere that had texture rendered from the same camera as the display in windowed mode (only had 1 camera at this time) and it didn't lag at all, but then i started testing stuff in fullscreen and didn't realize that at some point, my windowed mode got messed up.  

However, I noticed if I removed some of the objects in my world the lag vanished.  Alternatively, if I ended the windows process svchost (it was using 200mb of memory), the lag would basically dissapear as well until svchost was automatically started back up.  Not sure why that happens, I did notice that when svc host is terminated, the start menu bar on Windows 7 becomes a solid color instead of being transparent so I dunno if thats related to anything.

Hello, I noticed that if I have glfullscreen set to false my game lags quite a bit but when i set it to fullscreen it is perfectly smooth.  Is this normal?  This started happening when i tried to add in a mirror which is basically an object that has a camera that renders to the object's texture.

Hey I have this mp3 file that i converted to ogg and when i play it (im using backgroundmusic, havnt tried quickplay) right before it starts theres like a split second of a loud screeching sound.  Do you know how I can fix this?  I also tried converting it to wav instead but it still has that sound.

i dunno, if i didnt set the environment mapping it just showed up as a weird solid color that would change colors when i moved the camera but it didnt really look like anything.

wow I totally forgot about skyroads but as soon as i saw your screenshots i remembered that i played a game exactly like that all the time a million years ago when i was basically a baby
