Only tried online for the first time the other day. Me and my dad(sorry my dad and I) used the "inbuilt" multiplayer system in fs9 to fly together over a local network. The planes "sunk" into the ground, which we coul live with I guess a quick press of Y.Q.A.Y solved that temp. But the main problem was jumpyness. When our aircraft were close together (within half a mile i think it was, maybe less) everything was great, nice and smooth, but if we seperated we would see each others aircraft jump irratically around the screen. Until we closed up again.
Quick search on google showed up a result that said to get rid of those two problems use FSHost. So we downloaded, fired up with high expectations but alas exactly the same result.
Any ideas what the problem is, or is it just something that happens and has to be tolerated? Flying online is something I have little knowledge of so I know not if this is the norm, and my expectations are too high.
From memory.. the problem you describe was always there :think: Make sure you have 'Crash detect' turned off.. this may improve things slightly.
, shall give your suggestions a try later on. We'd fiddled with the scenery settings but only to set them the same on both machines, didn't try reducing things.
