So, not necessarily launchbox related, but it occurs when using launchbox...
I repurposed my old desktop into a launchbox-dedicated system, hooked up to the TV. It's running Windows 8.1, and the gamepad is the Xbox360 controller. What I've noticed is that when I'm playing a game with the gamepad, after a few minutes the system gets incredibly choppy and slow (this is any game - from playing in FCEUX or SNES9X or PCSX2, up to windows games like Borderlands 2 or Deus Ex). This is a system that runs with Windows Update disabled and no anti-virus, because I want it to have as much resources available for gaming.
At first, I'd hit ctrl-shift-esc to bring up the task manager, and see if something was eating up resources, but there wasn't. What I discovered is that all I had to do was hit any key on the keyboard - space, letter, number - and instantly it would come back to normal speed... until it happens again in a few minutes. All the power-saving settings are disabled (even the advanced settings, regarding cooling of CPU) - I thought it might be the disk powering down, but it doesn't appear to be as a result of power-saving settings. Of course, if I'm gaming with a mouse and keyboard, it never happens, because... well... keyboard.
Any ideas? Thanks in advance! :)
