BES is GPL free software that controls per-process CPU usage: an “active” software CPU cooler. It throttles CPU-hungry application(s) when asked.
BES works on Win7/Win10/etc. (if necessary, run it in the XP compatible mode—probably not necessary), but perhaps run it with the admin privileges (right click > "Run as Administrator").
It is a small tool that throttles the CPU usage of the process you “target”: for instance, you can limit the CPU usage of a process which would use CPU 100%, down to 50% (or any percentage you’d like). With this, you can use other programs comfortably while doing something CPU-intensive in the background. More Info »
By limiting the CPU load, you can also cool down your CPU immediately when it happens to get too hot. It’s an “active” software CPU cooler. Conventional soft-coolers save CPU energy by making CPU sleep when it is idle. They passively wait until CPU gets idle. BES is more aggressive: it cools CPU by making the “heating” process slow down, i.e. periodically forcing CPU to be idle for a short time.
Furthermore, BES can hide a window you don’t want to be seen for some reason, without killing the process, and restore the hidden windows again anytime you like.
To Gamers: Adjust the Sleep/Awake Cycle in [Control] so that the video won’t get jumpy/choppy. You can also control the parameters via command line.
