Long story short, got 2 graphic cards, Intel 4000 and GeForce GT 650M in my Alienware 14 laptop.
When using Intel 4000, its slow and lagging, so I followed all the instructions to switch it to NVIDIA graphic card.
But when I double click it, it still uses Intel 4000, worked properly but very slow.
And I closed it and open it again with right click -> use high performance NVIDIA graphic processer.
Nothing happened. I opened it again, it says its already running that I can't open '2 Lumions in same time'. Checked Task Manager, its not listed in the 'apps' but rather in the 'Background Processes'.
Plz Help!!! Thanks!!!
