We've noted that we're working to address this issue before but it's been buried in the thread, so I'm including the response note in the original post. We are still working on this issue but there is no ETA yet.

The issue has been narrowed down by the community to the UI which uses the AutoDesk Scaleform UI.
http://gameware.autodesk.com/scaleform
Basically the UI isn't being rendered by the GPU and is hogging most the CPUs resources causing a CPU bottleneck. The GPU usage for most including me is around 30-50% at even the most intense moments in the game and having the settings at lowest or highest settings make no difference in the FPS. If people hide parts of their UI their FPS gets a bit better for each part hidden. And if people hide their UI completely (Ctrl + Z) peoples FPS doubles/triples and the GPU usage goes to 70-100%. The issue apparently didn't exist in Close Beta and was introduced during Open Beta/Head Start. The Scaleform UI is capable of Multicore and GPU rendering so it should just be a matter of enabling GPU rendering or something along those lines. I just know that this is hindering many peoples enjoyment of the game including mine. As fun as tanking 60 dungeons is with no UI it'd be nice to see my HP and stuff....
I understand the game is still new and I'm sure the developers are busy getting content ready. But there is a large UI issue that is plaguing many people and there has yet to be a single response acknowledged by a moderator or anyone that can get the word to the devs. This same issue happened in Batman: Arkham City and was fixed with a patch so we know it's fixable... The Devs just need to know it's a problem.
Here is a list of just a few of these post. The largest one being on the Tera EU forums and is the most active and largest post there (300+ post)

My current set up for those that just brush it off as lack of a decent system:
AMD Phenom II 1090t 3.8ghz 6 GB Ram Nvidia 460 GTX
TL;DR - Hiding UI (Ctrl + Z) increase Double/Triples FPS and GPU usage goes from 30-50% - 70-90% for many people. Fix it or at least lets us know you know!

I'm still going to say it is partially system based as well.

this would be better suited in the technical help section. The general section is for people to complain about dumb issues in the game, not a relevant, well-thought out post such as yours :)

There is no technical help section, just that [filtered] answers garbage.

I agree with the OP. This area is in need of immediate attention.

Agreed.

wow I just made up a section, my bad didn't mean to get your hopes up lol. What about the support section? Or the online support?

I've tried to mimic this issue, but my computer doesn't have the problem at all. I knew a few people that have computer problems with this game that kinda sucks I want everyone to enjoy the game at the level I can.

No no, it used to exist. I don't have the problem either, but I know people who do. It seems to be hardware/setup specific.

I'm glad you're trying to get this seen widely by En Masse. It is honestly a really huge deal and DOES affect my performance when it comes to HM's for sure.
