Poor Performance with High end PC - Tera Online

Yikes, that is quite choppy. As you've already tried all different settings my recommendation (if you haven't tried this already) would be to change your Graphics Drivers - sometimes a simple incompatibility in a driver can cause issues with games (try the latest driver, if that doesn't work try some older ones - I believe you can get legacy drivers from Nvidia's site).

I would say also check latency (connection between your computer and the servers) in-game but based upon the video you provided I'd lean towards a graphics issue.

Hi Morty.

Thank you for the reply, I think I can certainly say this is a graphic issue.
The latency is always at green at I have a rather fast internet connection, server is not during populated time as well.

I tried you suggestion and downloaded 3 different Nvidia GTX 780 Legacy Driver, even the betas, which also yeld no result or any improvement.
Here is a thing I notice though. In game, if I happen to be in town where multiple npc and player is present, the choppy is very constant, but outside in fields, the frame seem to be more stable, but choppy and fps drop is still present.
Another thing that I'll like to add is that the FPS is stable as long as the camera/character stay still, I can get a 80-100 fps for hours as long as I don't move the camera or the character, but as soon as I move, instant fps drop/choppy.

Thanks again.

Sounds like it has issues re-drawing moving items (towns and the like in MMO's are havens for numerous players so you tend to get more slow-down as people move about where open fields there's not as much movement).

All I could suggest is reset the Nvidia settings to default and then go through the game settings one by one toggling them on and off to see if one particular one makes a difference (from experience it usually ends up being vertical sync, triple buffering, anti-aliasing, refresh rate or lighting effects). Aside from that it could be a bug with the game itself - maybe something it doesn't like on the graphics driver/card?

The only other test I could suggest (if you have access to one) is to try a different graphics card, ideally a different type to the one you have (if possible an ATI/Radeon card) to see if you have the same issue. I once bought a game that would not run at high resolution (above 1024x768) unless it was played using a Geforce graphics card (had an ATI Radeon at the time) and it wasn't until I swapped them over that I discovered the problem.

Hi Morty

Yeah the whole town/cities lagging ins't really a stranger to us gamer, esp I've been through so many mmorpg.
I got an ATI Radeon HD 7770 from HiS, which is rather outdated, I would't mind using it but the pc case I bough are only designed for single card, and switching out the GTX 780 with almost half a grand for a 5 year old card just to play Tera is just absurd :/

I've tried find help on Nvidia GeForce forum which they suggest me its a compatibility issue and told me to try contact the developer, which I did and now they suggest it might be a software conflict but they have no suggestion other then then closing out back ground app to help the game run better (right.)

so yeah between this and other two places, I think I'm running out of options.
it's pretty ridiculous for a modern rig this expensive to under perform a 8 year old dinosaur computer which I had before that ran Tera perfectly.

I guess I should close this or something, seem like it's case impossible.

It's okay! I'm still on board with the game's dev and Nvidia, maybe they'll help me figure out something at some point.

Thank you for sticking with me, have a happy thanks giving!
