Power Management tools - Performance


I want to fully switch to Linux, but some bug is preventing me from doing so. Basically I'm playing source games (TF2, L4D2) on Steam (linux) and then my framerates drop from 150 to 10 after a few minutes. I noticed that it's caused because the cpu governor puts my cpu clock down. It's fixable by Jupiter but this program is discontinued, so I want to know from you: What power management tools are there? SIMPLE ONES, please, I'm not an expert. I tried changing some scripts like "ondemand" (sudo update-rc.d -f ondemand remove) but it doesn't work, if you know some commands that put my cpu clokc to ALWAYS PERFORMANCE, please tell me.

Create a script with this content:
Code:
#!/bin/bash
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu4/cpufreq/scaling_governor
echo performance > /sys/devices/system/cpu/cpu5/cpufreq/scaling_governor
Of course you have to choose the numbers based on the number of cores you have (this is for my six-core machine).
Make the script executable and just run it as root (or with sudo, depending on your configuration)before you start gaming.
If you want to go back to normal (to lower your energy bill and temperatures) just use a similar script where you replace performance with ondemand.

Alternatively you may find a plugin for your panel (you didn't state which DE you use).
