Problem with recognizing of videocard nvidia for laptop
Hi.Few days ago I noticed that League of Legends runs slower,it decreased from 100+fps high quality options to 30-60 fps at medium quality. After,when I wanted to install the driver for video card,it said that he cant find any compatible devices with the driver (I selected my video card-NVIDIA GEFORCE 610M -for laptop).Now,when I check in Device Manager at display it shows just the integrated video card (Intel hd graphics-from processor I think),without my dedicated video card (nvidia geforce 610m),like usual. When I right-click into desktop It doesnt show anymore Nvidia properties/options,as before.
I mention that my laptop is lenovo g580 (I have it for 3 years,or maybe more). So..What happened?Can you help me? Thank you.Have a good day!
