Forgot to mention that on low graphics and on performance mode is more cpu bottleneck : D

Those who r getting low fps check you ram frequency, for 3200 ddr4 ram it’s 1600mhz on cpuz(software which tells ur specifications) DDR(double data rate) = 1600mhz * 2 = 3200mhz. If you r getting less than 1600mhz on cpuz than go to bios and update to 3200 (tutorials are out there).

can i get same performance on i7 3770 ?

Can it gwt samw on i5 4th gen

bro your gpu needs thermal repasting very badly its not built to run that hot on fortnite it should stay between 60's 70's dont go for a cheap thermal paste repaste it asap
