Macbook Pro 13" Retina Late 2013 issues

Hello,

I know this is a long shot, but ey... Is anyone else experiencing lags while scrolling heavy loaded safari webpages, UI lags and slow performance while working with Photoshop, Illustrator on a scaled resolution? My specs are i5 2.6ghz, 16gb of ram, intel iris 1024mb gpu and 256 ssd. I was always a fan of apple since i bought my very first iPhone, then followed by an iPad, however this new macbook pro has disappointed me. Is there anything i could do to minimise lags and increase performance without having to set the resolution for "retina recommended"?

Any feedback is appreciated.
