cool.
i'd also like to discuss/investigate a bit more, this issue of FPS drop on occasion.
it might not be pertinent to this thread, so maybe i'll move this particular conversation somewhere else - maybe the JetWar thread, or MiG21 thread...
but let me put my findings forward meanwhile....
i think we all know the issue of planes being hit by missiles, then they leave a flaming ball hanging in the air at that spot, and you can even padlock this fireball, as if it is a plane.
i had a close look at one of these fireballs, a MiG-21 which i hit.
under normal observation, all you see is the fireball.
however, when i pause the action on this spot, i see the rockets of the MiG sitting at the same spot.
also, quite often(it's hard to spot, though) when a plane lands, and then disappears, i noticed a 'blur' of motion along a straight line where the plane disappeared. examining closer, and also having to pause to see what it it, it's like a 'line' of the same two rockets moving rapidly up and down along this line.
barely visible to the naked eye at normal speed, but it happens quite often, and there is a flurry of java missile exceptions running with it.
i suspect this is at least partly the cause of these issues.
hard to describe, though - i'll try and put up an animated gif a bit later, to help illustrate what i'm seeing.
in the cases i tested, the planes were equipped with the K5Mf rockets, and it's these that are 'moving about' on their own, either after a plane is hit, or disappears after landing.
i may be wrong, but i suspect this has something to do with the seemingly random slowdowns in FPS.
