I used to be getting around 300fps+ on CSGO with these specs. i5 6500, GTX 960 4GB, Crucial Ballistx Tactical DDR4 8gb and a Gigabyte H270 Gaming 3 motherboard. I've lowered my settings to the lowest but on 1920x1080p. I didn't have this problem a month ago. I'm currently getting around 100-150. Any help?
