If you have an HTPC hooked up to the tv, try moving the mouse around. It feels like it's moving through sludge and is hard to control due to the 100ms+ lag. The difference between 17ms(W802A game mode) and 39ms(F7100 game mode) is in the realm that only twitch-gamers will notice though.
One thing I don't understand is how people tolerate 100ms+ of video lag when not using an HTPC video player that supports arbitrary audio delays. Do most receivers let you delay by such huge amounts now days? Mine only allows 0 or 60ms.
I'm not trying to pass off a 1/10 second latency as negligible, I just think it's something most people can live with quite easily and compensate automatically for. Of course I wish it was better, but as you've said (and I agree) Game Mode is a good remedy (unless the micro dimming becomes a problem.) I just wish it wasn't such a PITA to activate. I don't have an HTPC setup, but I understand where you're coming from that you would probably notice a slight lag there, which the PC label pretty much takes care of if others are to be believed (I can't speak for it's impact on PQ however).
I'm not sure that most people can really hear the 100ms+- audio lag (maybe we'll just have to disagree on the feedback threshold). I can only speak for myself but I output my sound using Toslink to my speakers (I know its only 2.0, but my setup is only 2.1 anyway, my delay is set to 50ms and it can go as high as 250 when outputting digitally from the TV) and neither myself or anyone who's watched something with me has found a problem with audio sync. Plus, even with your setup you're talking now about 40-50 ms of audio lag which is honestly barely audible. I completely understand the drive for perfection (or at the very least minimal delay), but I think hard numbers just make it more perceptible (or perhaps seem like it).
I guess what I'm saying is, for a majority of people, it's more than good enough with or maybe without just some minor tweaking. I'm not saying that's right, especially for a piece of 2013 technology worth 1000's of $$$, it's just reality. I'm actually glad there are people like you, they keep the Sonys and Samsungs on their toes in terms of quality. :-)
