Multiple Game errors

[Cairo-Bochama]

As stated in the title, the game has multiple problems for me. There is a lag n the game, and mouse movement/ character movement is lagged, as well as the reaction to commands.*My summon racoon*wont summon, no matter how many times I right click and presss "OK". The server is often disconnected on its own, and and there are times where the game just crashes and my player is inactive while the world and other characters keep moving.
