I wish I could easily recommend this, but the unstable framerate undocked is pretty distracting.
Sorry you had noticable issues! I'm not really a "visual" person, in terms of what I focus on (graphics are only worth 10% of my reviews). Framerates have to be REALLY bad for me to notice. My brother in law is a pcoverlord and pretty much anything under 60 fps he notices and is bothered by lol. For me, I can barely tell the difference unless I'm watching side by side videos. It would have to dip below 30, or maybe below 25 for me to notice.
One game I DID notice on was Arkham Knight on PC (before they patched it). My goodness was that a complete nightmare, and I have a 980 ti gtx! lol
