You're getting similar performance at 4k Max on a 1080 ti/i5 6600 than me on a 2080 ti/i7 7700, are you using dynamic res?My 1080TI and i5 6600 running between 50-60fps 4k maxed out, but alas I get annoying stuttering which sometimes devolves into an alarming beep sound 2hrs into game. Got the texture pack. Going to update drivers and see if that changes anything haven't updated in months...
