Are you using a Windows PC?
If yes, hold the Window key (between Control and Alternate on the left side of the keyboard) and press 'R'.
In the run field, type in 'dxdiag' and hit OK. If a prompt about driver retrieval appears, hit OK.
Once a window called "DirectX Diagnostic Tool" appears, hit the button that says "Save All Information..." and save the file (dxdiag.txt) somewhere easily accessible to you. Upload that file here.
Since you said the GraalOnline website lags for you as well:
When you have done that, press Window + R again and enter 'cmd' this time.
In the command prompt, enter 'tracert
www.graalonline.com > C:\tracert.txt'
This will create a file on your C: Drive called tracert.txt. Upload this file in addition to the dxdiag.txt.
What cbk1994 appeared to be asking was whether it is a latency issue or frame rate issue.
Does the game appear to "stutter" and you see yourself move slowly, or seem to jump around erratically? If not, do you see players move erratically (teleporting, stopping and then moving rapidly to another spot) then?
