I recently built a pc with a threadripper 2950x , rtx 2080, 32gigs of dual channel ram ( 3000mhz). I saw on YouTube that people are getting much more fps in gaming than I am. Like i just saw a benchmark of rainbow six siege at 1080p ultra and the Average framerates are 300-330fps. But i only get 100-120 average fps. Similar in all other games. What could be the issue here?
