The first patch for EVE Online's week and a half old Quantum Rise expansion is up today with several crash fixes and performance tweaks. The complete patch notes are as follows:

Quantum Rise 1.0.1

• Fixed an error that would occasionally cause a ship to disappear after jumping through a gate. This error would also cause client delays in loading up the space scene and models after the jump.
• Fixed performance issues that would occur when loading a scene when running 2 or more clients at the same time, such as when docking.
• Fixed a performance issue that would cause client slowdown after 30-45 minutes of playing.
• Fixed a memory leak issue when ships appear on screen.
• Fixed an issue that could occasionally result in a crash when switching effects on and off while in battle.
• Fixed a memory leak that would occur when loading a large numbers of models
• Fixed an issue that could cause a crash when entering warp.
