Hi. I have laptop with AMD Radeon videocard. When I tried to turn on the high-performance adapter in global switchable graphics options mpc-hc.exe (mediaplayer) the Catalist show me that for compatibility this application is blocked. What is the difference of this mediaplayer with any game (applications where switching is allowed)?! I have too much freezes in high bitrate videos and fact that I can't at least a little improve the situation because of the Catalist for me decided that I do not need it is infuriates me.
