Stilted ground view

[Baine]

I've noticed when flying close to the ground near bases that my video suddenly gets stilted and choppy, this despite the fact that frame rates remain fairly high (in the 30s) at the time. It happens when flying around damaged bases, (lotsa smoke) and intact bases (no smoke).
For example, if I try to bank, instead of turning smoothly, the plane turns in increments, as if I were experiencing really low frame rates. It doesn't seem to happen when flying near water, and carriers.
Any suggestions?

I found that with my radeon and radeon 8500 cards, if I turned off the "wait for vertical synch" option in D3D settings, the type of uneven movement close to the ground goes away. I also could get rid of it by getting rid of ground clutter, but I like ground clutter so this was my solution. Hope it helps.

I'd forgotten all about clutter on/off.  Tried that and found things are working fine.

The best idea is just to turn ground clutter off with CNTRL-C.

Disabling V-synch may have other side-effects, specifically a few have reported cases of "rubber bullets", or not being able to score hits on other planes when V-synch is disabled.  Although Disabling V-synch will make your framerate number go up, there are frames getting drawn that you won't see, or will only see part of due to your monitor refresh rate.  I would only disable V-synch if I was benchmarking a video card... that's really the only reason that option is available.

Lepthurn, your link to 9x det drivers contains beta versions not whql versions.
