 #
 # A "default" érték az alapértelmezett teljesítmény-állapot profilon hajtja a videokártyát. Ez az alap viselkedés.
 # Az "auto" érték a "mid" és a "high" értékben definiált szinten tartja a kártyát, attól függően, hogy akkuról, vagy hálózatról megy-e a gép.
 # A "low" érték kényszeríti a GPU-t az alacsony fogyasztású profil használatára. Néhány laptopon hibát okozhat, ezért sem használja az "auto" mód.
 # A "low" érték vissza tudja szorítani a fogyasztást és a ventillátor sebességét, de nem lesz akkora a videoteljesítmény.
 # A "mid" érték az arany középutat választja, közepes fogyasztást és teljesítményt ígér. Ha a képernyő kikapcsol, átvált "low" üzemmódba.
 # A "high" érték a legmagasabb órajelen pörgeti a kártyát, terheléstől függetlenül. Nagy hangja lesz a videokártyának, nagy lesz a fogyasztás, cserébe a # legnagyobb teljesítményt nyújtja. Átvált "low" üzemmódba a képernyő kikapcsolásakor.
 #
 # A "dynpm" érték dinamikusan változtatja a kártya órajelét, tehát nagy órajelen fog menni a kártya a nagy GPU teljesítményt igénylő alkalmazások
 # futásakor, kis órajelen amikor nincs terhelve. Ha ez van használatban, akkor zavaróan villoghat a kijelző a GPU órajel változtásakor, szóval más
 # profilt kell használni ha ilyen jellegű probléma adódik. Főleg Compiz Fusion-t futtató embereknek szól!
 #
 # "default" uses the default clocks and does not change the power state. This is the default behavior.
 # "auto" selects between "mid" and "high" power states based on the whether the system is on battery power or not. The "low" power state are selected
 #  when # the monitors are in the dpms off state.
 # "low" forces the gpu to be in the low power state all the time. Note that "low" can cause display problems on some laptops; this is why auto
 #  does not use "low" when displays are active. (Can reduce power consumption and fan speed.)
 # "mid" forces the gpu to be in the "mid" power state all the time. The "low" power state is selected when the monitors are in the dpms off state.
 # "high" forces the gpu to be in the "high" power state all the time. The "low" power state is selected when the monitors are in the dpms off state.
 # (When the high value is in use, the fan will be noisy, there is more power consumption, but we have better performance)
 #
 #
 # The "dynpm" method dynamically changes the clocks based on the number of pending fences, so performance is ramped up when running GPU intensive apps,
 # and ramped down when the GPU is idle. The reclocking is attemped during vertical blanking periods, but due to the timing of the reclocking functions,
 # doesn't not always complete in the blanking period, which can lead to flicker in the display. Due to this, dynpm only works when a single head is
 # active.
 # Dynpm can cause display flickering especially on Compiz Fusion! Use the others instead if you experience problems!
