Didn't fix any of the issues that are really serious:
The ping issues: Flyff Community • View topic - Pings are too high
And the keyboard typing issue / GPU overload issue while in fullscreen: Flyff Community • View topic - Insufficient Texture Memory, etc.
The following issue however isn't as serious as the two above:
Flyff Community • View topic - FlyFF Says "Game Hack Found" on Item Mall Randomly
Tried it myself. No options to change between full and windowed mode in the launcher still. Have to login to change. Still laggy as hell. Still can't type outside of flyff efficiently like before. Same crap issues. Why haven't they fixed them?
Also, what's with the white screen on alt+tab? What are we? Asda Story?!
