Windows 8 Playing Ragnarok error

[LionHeartAllStar]

Dear All,

Currently I have a few friends that are unable to play RO smooththly due to using Windows 8 platform. Tried Regedit, but they are now facing what
I think is called 'mouse lag' by most windows 8 users when entering any fullscreen game mode.

Any help or suggestions?

NOTE: Did my homework on googling and such, but to not avail. Any help is much appreciated. Thank you.

This has always been the issue of playing RO on Windows 8 tbh. Back then I did everything suggested, couldn't fullscreen. I can use window mode that matches my screen resolution but yes, it was pretty laggy.

Hence on my server seeking topic, this is another issue I pointed to you. I am a Win 8 user and looking for a server which can design some kind of script/add-on which makes Win 8 user play as per normal.

inb4 "just wait for Win 10". I don't think that'll fix the compatibility.
