i have lenovo z50-75 with AMD Radeon R7 1GB and R7 M260DX 2GB(switchable graphics) and i have 1 problem for a long time. I cant use dedicated one (M260DX). Every game uses integrated (R7). I switched power play to maximize performance, in graphics settings i switched everything to maximize performance, but nothing worked, i followed youtube instructions,, nothing worked. I cant just use that gaming graphics card. All games which were suppost to run on 60+fps are running on 25 on lower preset because this laptop is using integrated graphics. For example AC3 works on 60fps on high preset on dedicated graphics (youtube,gamesystemrequeirements.com) but i can play it only on 25fps on low preset. I just cant switch to dedicated one for some reason. It never worked in this pc, but i never solved it, but now it annoys me.Sometimes it shows that game runs on M260DX, but all is same, fps low, everything lagging. HELP PLS
*i have windows 10 64bit, processor AMD FX-7500, Integrated AMD Radeon R7 1GB, Dedicated AMD Radeon R7 M260DX 2GB, 8GB RAM
