My experience with GFN has been MUCH better than I expected. I've also come across similar sentiments as yours, which leads me to think it's a proximity to the DC issue. E.g., my RTT to my ISP's gateway, on average, fluctuates between 8-11 ms (currently ~14 according to pfSense) and a ping to google's closest response is usually about the same. I'm sure others have it better, but I am quite impressed, given a little bit of this latency would probably be eliminated by not having a virtualized router as is the case with my setup. Twitchy MP shooters and twitchy platformers are the 2 subgenres that aren't suited for this arrangement. Most everything else is perfectly fine (under the aforementioned ideal conditions).
