Re: Want to get back to EO but cant go full screen and bad lags.
From some topics I saw that you can try to run the client with compatibility mode for Windows XP, and maybe try in the setup.ini:
Fullscreen=off Sizeable=off Pageflipping=off
but then you'd not be able to go fullscreen. Also, manually update your graphics drivers. Maybe try Sordie's EO Addon called EOSoftwareRender.eaf, though I don't know where to download it
