AHHHH!!! I have the exact(EXACT)same problems...I've been trying to figure this out for more than a week now. I'll have an object clip that is easily over the clip_near thresh-hold and under the clip_far....usually setting the fog and clip distance ridiculously high fixes most of it, but that causes other issues(frame rate) and I still get the random clipping. I can't figure it out, it seems semi random...usually rotating the camera on it's tilt and pan a little brings the model back into view, but it clips again once player movement begins...this also happens to the player, wich is about 200-800 quants from the camera.???????
I get the d3d error as well when doing a video switch(not f5, but using the script command).
-thanks jcl, I know you guys will be able to get a handle on this...I'm running an Nvidia 7600 GS(with current drivers and Aug 2007 DirctX 9.0c)
