Multiplayer Plugin peer sync

I have a problem with the realtime multiplayer peer sync .

Im using normal bandwidth , and high precision on my peer player sync with physics , but the collisions with gravity and against other objects is terrible.

Is there a way I can increase the bandwidth sync to the peer. because normal bandwidth is just not accurate enough. will the multiplayer sync work better if I get a better if I get a dedicated server to be the host ? and will a server be able to handle a thousand rooms of 2 players each?

I don't know maybe there's a way I can hack the bandwidth amount to High?

Any suggestions?

Have you measured how much bandwidth you are using at the moment ?

Have you disabled all the behaviours on the peers to ensure local simulation doesn't conflict with the host updates ?
