dx11 / performance mode is almost unplayable as i get 100 fps in fights and really laggy , but when on dx12 my fps doesnt go below 200 , performance mode on fortnite gives you a advantage because of lower input delay and better frames ( for nvidia users ) And makes it alot easier to do stuff in fortntite a fast paced game , i need a fix or some better drivers or something because if it doesnt get fixed i will be buying a nvidia card
