For those who are talking about the phasing and following and such -- do you have 280% (or faster) flying mounts and using them in Northrend?

I just hit 77 yesterday and bought cold flying, and honestly it was a bit frustrating. Just flying over a single zone (no phasing) and team members would constantly disappear for a few seconds and then reappear, dunno if it was server lag or my PC not being able to handle it. As a test I went back to Outlands and flew around Terrokar forest and SMV, no problems following and nobody fell behind.

In Northrend however pretty much every 20 seconds someone is gonna fall behind and get stuck, or appear that way on my party window/minimap causing me to constantly go back and forth trying to "gather the flock". I've had 0 problems btw up till now on land mounts. I have gotten into a pattern of inching forward a bit, waiting a few seconds, then inching forward again. Not exactly the thrill of epic flying I had in TBC. And yes, my graphic details are all the way down (experimented a lot last night).

Its probably just my underpowered PC, hopefully upgrading that will help a lot.
