All modern televisions have processing that goes on. Plasmas tend to have a little less of it in my experience, but they still have some. One of the reasons the "edge-enhancement" that was talked about during the shootout is non-defeatable is because Panasonic's engineers didn't provide a bypass for the Viera connect module, which induces the effect. All of these ASIC components induce some latency... the game mode just has the fewest number of them in play.
As for if anyone has measured game mode vs. other modes (such as ISF/Custom/THX), I have no idea... not that I've seen. Any reports, including mine, are purely anecdotal and qualitative. IMO it's nothing to worry about. The Game Mode is bright, it looks pretty good and you still have basic controls (brightness, contrast, color level, temperature), and the other modes, while they feel worse, still feel somewhat playable to me.
I set my Game Mode to WARM-2 and it doesn't look that far off from my calibrated ISF Day setting (so far... it's still a work in progress).
