BigBox background CPU usage
Issue #2295
new
Version: 7.4 Windows: 10 Issue frequency: Always Steps to reproduce: Open any game, while BigBox continues to run in the background Problem: Idle background CPU usage around 4-10% on an i5 3570K at 4.5Ghz, this seems excessive & results in frame drops on CPU bound games. Can an option be added to kill the BigBox process and resume upon quitting the game? I can do this manually with a script, but it would be nice to have the option.

I noticed the same thing and was experiencing frame drops. Before I found this request, I created Issue #2345.

I've been getting this too, and from what I can tell, it's only happening with VLC as the video playback engine. I hooked up a profiler to BigBox.exe to see if I could tell what was going on. From what I can gather without the debug symbols, it looks like VLC might still doing all the work to render video frames while the game is running. There are a couple threads spending almost the entire time busy in native code and making inexpensive callbacks to VideoDisplayCallback and VideoLockCallback.

Also, it still happens in the latest beta (Version 7.5-beta-6)

I use Windows Media Player and have this problem.

sounds like what i see when using launchbox.exe
According to Performance Monitor, while logging cpu usage for launchbox.exe only when a game is running and in focus, it is showing ~11% cpu usage exactly every 5 seconds. I have 4 cpu cores. I don't think that will help me when running cpu intensive games and emulators.
from what i have been told in forums by jason, LB uses cpu every 5 seconds for a cache refresh, but isn't supposed to do that when not in focus like when a game is running and in focus. seems like a bug to me, because i have prove with performance monitor that the cpu usage is real when running games from LB. i hope jason will look into this.
