I played during Open Beta as well as shortly after Release and experienced these two issues. I've recently come back to the game hoping that these would have been fixed by over a year of video card driver updates or game patches, but it appears they still persist.
Camera Stuttering: It appears the game uses two different "behaviors" for the camera, with each one presenting this issue slightly differently. When using the mouse to control the camera, it seems as if the camera gets "caught" on any terrain that is not mostly flat, causing it to zoom in slightly (as if your back was to a wall and the camera zooms in as to not clip through it) and then immediately pop back out to your chosen camera distance. This causes the *terrain* to look jagged and stuttery, especially when walking downhill. The second case is when you use the keyboard to control the character. In this case the terrain still stutters, but typically much less, and instead your *character and nameplate* stutter instead. Again, the effect is most prominent when the camera is getting "caught" on walls or if you are walking downhill and it is getting "caught" on the raised hill behind your character, but in this case seeing my nameplate jitter up and down like i'm playing through an earthquake physically gives me a headache.
The second issue is a fairly awful case of screen tearing. It occurs and sort of moves up and down the screen like theres a wavy line moving up and down, but tends to favor the bottom half of the screen more than the top. It generally appears when i'm out in the field (when theres less going on and my FPS would be higher than 60) and goes away entirely in town when my framerates usually dip between 45 and 50. I typically have screen tearing issues in games so I keep Vsync on whenever the option is available, however there is no in-game option for it with FF14 and the "force vsync" options in Catalyst Control Center don't seem to do anything at all with FF14 (i've tried all 4, same issue).
My specs:
AMD Phenom II x4 955 Black Edition 3.2 Ghz
Sapphire Radeon HD5850 1GB (only hits about 76C under max load, 11.11 drivers)
4GB GSkill DDR3 1333 RAM
Windows 7 Professional x64 (fresh install on a brand new SSD)
OCZ Vertex 3 120GB SSD
25.5" Asus LCD monitor @ 1920x1200: 60Hz
I've seen a few older posts about these issues but with no resolutions, is there any word on a possible fix, or is this more of a "wait for the new engine and pray it gets sorted out" sort of thing?
Thanks.
