So, did you ignore my post? Because I clearly addressed the fact that some games are capped at 60fps by default, sometimes with or without v-sync.

But if your issues extend beyond that, I am unsure what is causing that.
And the VG248QE simply does not excel at image quality from any standpoint. I've got mine "good enough" with ICC profiles (for with and without LB, because that does matter) and some minor tweaking using the monitor's menu itself. I don't need the best image quality to browse the internet, and smooth, blur-free motion is infinitely more beneficial to me in games than picture accuracy (again, monitor is "good enough" in that regard). Without smooth, blur-free motion, I easily get tired eyes, a headache, motion sickness, etc.
Better picture quality doesn't actually produce tangible benefits for me other than "it looks better."
I also don't exactly have room on my desk for a 27" monitor, as my current 24" monitor is sitting quite snug between my two desktop speakers. And some games I can barely push at 100fps at 1080p. I'm not sacrificing picture settings (to an extent) to go to a higher resolution with much greater motion blur and a potentially lower refresh rate. 1080p works very well for me with my GTX 780 and 2500K @4.5GHz, even with a good portion of new, demanding games.
