Re: [hlcoders] Engine Memory Leak
I can confirm this for our OB based mod. The MP3 leaks memory but the WAV does not. This is really bad, our sound guy is not very happy to use WAV for everything. Do we have an official bug report for this? On Sun, Jul 12, 2009 at 5:52 PM, Justin Krenz kre...@gmail.com wrote: MP3s don't appear to be cached.

Playing the MP3 sound effect in my mod used up about 100 K at a time. I think it's probably related to how big the MP3 file is. Run your mod in a window with task manager open, and watch how memory changes for HL2. That's how I found the source of the leak. Memory should be stable while your mod is running. Perform all of the actions that might normally occur in your mod while watching memory. See if you can find an action that consistently causes memory to increase.
