I have tried vsync on/off, fsaa on/off, AF on/off. FSAA,etc. are set to application control in the CCC. I haven't exhaustively tested every combination yet, but I've messed with most of the basics.
I'm not at home right now, but I'm going to go down the list tonight and see if there is anything I haven't tweaked.

If it's not visible in screen shots... it might be the monitor.
Try another monitor if you can.

Besides ensuring that Vsync is on, try making sure you are using the native refresh rate of your monitor. You probabaly already are, but it's something else to look at.
Checked both those things re: the monitor.
Whatever my issues are seem sporadic, it's driving me a little bit crazy. I haven't seen the line I mentioned in a few days. But...
Currently, when it has problems, the problem it has is "chunking" as I turn. Ie the framerate slows way down, but only as long as I am rotating. Moving forward, etc. works fine.

I think i know what you mean, and i sometimes experience the same thing. If I spin around in an area I just went to, it'll be kinda rough, but if I spin a second time it's just fine. It's almost as if it's ceasing while loading the graphical effects (FSAA/Occlusion) in that area, and once they are loaded, it is smooth as butter. The same thing happens while simply entering certain areas without rotating at all. Once loaded, I can go back and forth to the areas just fine. Also, without those 2 options turned on, the problem seems to go away completely. I like thosee effects, so I can live with the occasional "chunky-ness" lol YMMV

Lobster, have you checked your 'Wait for vertical refresh' setting in Catalyst Control Center? If it is set to 'Always Off' that may interfere with the game's vsync settings.

I don't see anything with that label, is it "3D Refresh Rate Override" ? I have that set to "Disabled".

Lobster, in the CCC, under 3D, All, the third from the bottom section should be Wait For Vertical Refresh. Crank it to the right for Always On. Are you not seeing that section at all?|

Also at the bottom of that section, set Triple Buffering to On.
Be well, people of CoH.

Found it! I thought that section was just a summary section and hadn't even looked yet. Doh. Trying now.

Update: This last change seems to have stabilized my system, I haven't had an issue since then.
