i recently added a gtx 1050 to my old i3 2120 system that has a 2+4g.b ram running at 1333mhz .. and in a game like fortnite the cpu bottleneck should be minimal to non existing .. but i get 40-60 fps on the lowest settings and the gpu is running at 30-70% and the cpu at 80-100% .. why is that happening ? i also see benchmarks for the i3 and the 1050 running fine over 120fps .. and even lower end systems with core 2 duos and gtx 750s running over 100fps
