As I understand it, if I enable it, VSR renders the frame in... let's say 2160p (4K)... then fits it to my 1080p display supposedly giving me better looking graphics or something. Since 4K is 4 times the pixel area of my 1080p display, does that mean the fps will be only 1/4th of what it would be if I just played at 1080p (no VSR)?
