This has been happening to me regularly for a couple months now (I believe it started when the last version came out). I literally lose low flying planes in the ground. If someone dips below ~500 feet or so and I am above them, they disappear. If I drop down below 500 feet as well, they become visible again, starting with the icon and working down to the plane as long as I keep descending. This seems to be ~500 AGL, because I've lost people that flew very close to hills until I came up next to the hill to. I can still see their shadow on the ground, so I can keep track of where they are and sort of what they are doing, but it gets hard to dogfight sometimes when the enemy plane literally dissapears for a few seconds.
I've also seen it when any enemy plane was behind me and I was shooting out of the tailgunner position. Happened twice- once in a Lanc and once in a B26- a guy was coming up at about 1000 yards and just dissapeared- I could still see the tracers coming towards me so I knew where to shoot, and he "popped" back into existance a few seconds later though.
I'm a lot more worried about the invisible planes below 500 feet, as this can play a rather significant role in a dogfight
. My computer is a 900 mhz Athlon, with 256 Mb ram, and a 32 Mb Geforce 2 MX card with the driver file version of 4.13.01.1241. I've tried 2 or 3 other drivers with it, and the same thing still happens. I've got DX 8.0.
Could it have something to do with the way my video card is set up in Windows? Or possibly my video options in Aces High? Does anyone else have this problem and know how to fix it?
