Sorry SE, but endgame won't work if you don't fix something.

My brothers and I (A family of gamers) got together one weekend for a 4 man dungeon. I was unable to dodge any aoe with my older laptop. Sitting side by side, we noticed that my cast bar would show up slightly after theirs and would finish casting after theirs were already casted. After 45 minutes of deaths, I switched to a newer up to date computer and the problem with the aoe-lag was solved. We also tested this on an older gaming pc we built 5 years ago in WoW's day and it was also having the same problem with all settings set to minimum.

Whether or not we are all affected to some degree I don't know,the 100-300ms. The only way to actually test this is to have multiple same top notch computers test for the delay I guess and then for lesser computers and so forth. Testing it for yourself will just give you results based on your system I feel. Sitting side by side with my brothers clearly shows an older pc performing poorly, especially my laptop for aoe.

(Snip for word limit...)

It's not computer specs with me:
Windows 7 Ultimate 64 bit
Intel(R) Core(TM) i7-2600K CPU (a high-end CPU)
16GB RAM
NVIDIA GeForce GTX 690(VRAM 4014 MB) (A powerful gaming card)
Samsung SSD 840 Pro (was considered the fastest and most reliable SSD through most of 2012/2013 by most reviewers)

On top of having a Tier 1 ISP. On top of having a screen with the lowest delay possible (and still I capped at 60fps just in case). On top of having arguably (between three high-end) the best air cooler possible. On top of their benchmark telling me that I should be able to run laps around their game thrice over when I tested it (and became bored during testing and watched a 1080p movie during the test and even with those resources busy, I was told that my computer is more than enough for this game).

May I repeat that this is the only game in which I am having these issues.
