Hi guys,
I'm 14 years old and I need help for my new laptop Lenovo y50. I have not original Windows 8.1 and every game I have installed it lags.
I tried Far Cry 4;Assassin's Creed Unity.
They all lags! Even Assassin's Creed (2008).
Please help!
I think you meant you have a original windows 8.1
your y50 should play all those games fine, i have y510p (your laptop's older version)
you should check out if your games are starting with the nvidia graphics not with integrated graphics
you can right click on game exe and "select run with graphic processor" -> "high performance Nvidia processor"
also if you are playing on battery that might be the issue switch to AC power and then try
let us know if you face more trouble
happy gaming
