So i have this dell xps 13 with i7 6500u integrated graphics and when i try to play minecraft with it lags because of the amount of pixels.i want to turn it down to 720p or 1080p but when i do it looks terrible on the 3k display.most of the display when 720p or 1080p is blurry and only clear when 3k.help can i make it look good in 720p or 1080p?
