I recently bought an Asus notebook 15.6" Asus R-Series R558UQ-DM539D with i5-7200u, nvidia 940mx 2gb graphics card, 4gb ddr3 ram. I installed win10 on it. Firstly there are no resolution options available for my home screen or any game other than 1920x1080 and 1024x768. Second every game lags a lot, no matter how old it is. Fallout 3, for example, gives me a low fps of 10-11 on lowest of the settings. I have checked everything, drivers say they are upto date, all updates done, no heating issues. Please help.
