My config is i5-7500, gtx 1070ti with 8gb ddr4, windows 10. Serious issue in assassin creed origin. Sometimes it gets down to 40fps. Cpu hits 100% usage in all cores while gpu is just 66%. Is it all just beacuse of my cpu? Or is it another issue I should care about? My motherboad is asus h110m-k. As per as I know mobo is not concern here or because of low spec mobo I'm missing out some of my cpu or gpu performance? I'm really confused!!
