Hi there guys, I'm experiencing quite strange problem. I'm an owner of ASUS N550LF which originally came with Windows 8.1. The OS works great, but I'm not a big fan of the Modern inteface. I tried to switch back to Windows 7 - all works fine apart from USB 3.0 drivers (I had to disable it in BIOS and switch to USB 2.0). So, the problem occurs in games. While playing on Windows 8.1 everything works smoothly, on Windows 7 it's not. Using always the latest drivers, energy profile set to High Performance, NVIDIA driver set to High Performance / v-sync off. Playing CS:GO just gives me 20-30 fps less than on Windows 8.1! My laptop's spec is i7-4500U, 8 GB RAM, GeForce 745M, 250 GB SSD Crucial BX100.
