If your CPU frequency scaling governor is set to "Power Save" mode, you may experience performance issues in Warhammer 40,000: Dawn of War III. When playing games, we recommend that you set your CPU frequency scaling governor to "High Performance" mode.
Easy FIX (run in console as root):
echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
If wont permanently put CPU frequency scaling governor to "High Performance" mode (eg. after restart PC) simple do:
apt-get install cpufrequtils sysfsutils
Make file /etc/default/cpufrequtils if not exist, and write:
GOVERNOR="performance"
Add in file /etc/sysfs.conf
mode devices/system/cpu/cpufreq/conservative = 644 devices/system/cpu/cpufreq/conservative/freq_step = 10 devices/system/cpu/cpufreq/conservative/up_threshold = 45 devices/system/cpu/cpufreq/conservative/ignore_nice_load = 1 devices/system/cpu/cpufreq/conservative/sampling_down_factor = 10
After you made the changes , apply them with:
echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor systemctl restart sysfsutils
Now check CPU status with:
cpufreq-info
Enojy in game!
