HiDpi causing UI lag

When I select retina option which is basically hidpi , the whole ui starts lagging . For eg. minimizing windows . Is this normal? I know that in hidpi a 2x resolution is processed and scaled down to give crisp clear image , so it may seem like igpu (UHD 630 in my case) cant handle it.. but this is the same calibre of gpu as used in macbooks .. the processor is i5 9300h (coffee lake plus) and opencore version 0.7.2 with all latest kexts

edit: resolution is 1920x1080 .. so the hidpi stuff is rendering it at 3840x2160 and scaling it down
