Whenever I log in or undock, be it from citadels or NPC stations, I get a multiple minutes long black screen, that doesn’t go away even after 10 minutes or so. I’ve also been getting game freezes very frequently.
My laptop was more than capable of playing EVE at 60fps, with Low settings. Now I have them to minimum, and it does not help at all.
In citadels you can try to use Look Outside to preload external assets before you undock. The blackscreen after the first undock after logging in has become considerably worse after CCP updated the graphics the last time, in particular in busy systems.
