I Have a intel i7 8 core 3.06 processor, a GTX 970 MSI 4gb graphics card, my monitor is a asus with 144hz refresh rate and 1ms, I have 8gb of corsair ram (unknown exactly what it is) and a decent power supply. My friends have hardware that is no where as good as mine but they can run games on ultra with a solid fps and I have to run on the lowest and still get lag. I get so much fps drop from a unstable 57 to straight down to about 28 frames. I have tried to fix this for ages.
