My graphics card (Base clock 1mhz) overclocks to 1.2 Mhz when in game and underclocks to 200 mhz when idle and this can be sometimes troubling. For example, when playing less intensive games such as Garry's Mod the graphics card is barely being used and thus downclocks to about 600 mhz. This caused 20-30fps. Any way to temporarily disable this feature?
