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

People have used computer specs as an excuse for this and have not realized to calculate how much it really values in what you see on screen and reaction times.
I am not expert in calculus and these are just what ever comes to mind.
If a player has 10 frames per second which is a frame every 0.1 seconds if the frame occurs in steady intervals. This means the 0.3 seconds (rumored position check) + latency + invisible frame can actually cause you to see the cast bar and danger areas 0.5 seconds later than it occurs server side.

My fps is a non issue, as it's at 60 in a 4 man dungeon or a 8 man raid and I experience the flawed position check , latency or w/e you want to call it.
I'm pretty darn sure most people don't game at 10fps, so you can throw this theory in the trash. And the issue doesn't scale, or fluctuate based on fps.
Fps has nothing to do with it.

There is nothing rumored about the position check. It is fact stated by Yoshida. I have seen several posts in the last few days reference this as speculative or other synonyms. It.Is.Fact.

Lower end specs certainly can cause this issue to be more predominant. I have an i7 4770k, 8gigs of ram, GTX 760 OC and even I get this issue. This was built into the game by choice, and it was a bad choice. As many have said all you have to do to see the issue is Cast a spell and begin moving. The spell does not immediately cancel. Other ways, run up to an object and interact with it. Stone vigil is good for this. If you do not come to a complete stop and pause a moment you will start to use the object than get interrupted. Regarless though, I could quad sli titans and OC my cpu to 4.7 ghz and this issue would still occur because it is caused by their servers and not our machines.

well my free trial is up in a few days and guess what SE. i won't be subbing, because of this problem. good luck with pvp lol!

This.

The funny thing is the white knights in regards to red circles, their big solution is "move before you see it".
Clunkiest MMO I've ever played.
This isn't to say I don't care...I do, or I wouldn't have leveled to 50 or bothered posting on forum, but I'm done because SE clearly does not care.
