I have recently purchased a gaming laptop because I wanted to experience true 1080p gameplay. However, when i tried to play dark souls, it said the the executable wasn't working. So i tried to play Empire total war (a game from 2009) and it was laggy as hell. I don't know how to fix it and i would really appreciate it if someone could tell me how to fix it. My specs are: Intel Core i7-4700MQ Mobile Processor (4x 2.4GHz/6MB L3 Cache), NVIDIA GeForce GT 740M 2GB GDDR3 Video w/ NVIDIA Optimus [W650SR], 8gb of ram, and it is running on windows 8. As aforementioned any help would be greatly appreciated as i have paid of $1000 dollars on this laptop.
