Hola

first way is worked for me, this solution really increases performance of the card. For example, I am a fun of Warcraft 3 and I tested dota map on single player mod, low settings, resolution 1024*600 gives me 18-21 fps at war area. same spefications at medium setting i get 15 fps. 18-21 fps. The game is really playable not smooth but not makes crazy when playing

.
Thank varia for the advice.
