Unplayable Game

[Stuzack]

Some ISPs like to throttle FFXIV, because it flags up as P2P on their system. This would explain why you seem to get laggier around peak times.

I was with BT, and we were having terrible problems after 6pm. The game would be unplayable for hours. The only solution in the end was to upgrade to a new contract, which removed throttling, and this fixed the problem completely.

Please Try a Glasnost test to see if you are being throttled during peak times. Run this without FFXIV or anything else in the background. it will tell you if you're being throttled, and that might be what's happening to FFXIV.

And this "cFosSpeed - Internet Acceleration with Traffic Shaping and bandwidth management." sounds like a prime candidate for throttling your speeds too.
