Slow turning around

[GuyManDude]

I am running the Titanium client under Windows 7 x64 and everything seems fine except turning around is very slow with the mouse. I have to drag 7-8 times to do a 180. I have tried tweaking all the in game mouse/display options I can find but nothing has worked. I have also tried running the client in various compatibility modes and with single processor affinity. Nothing has worked so far. Couldn't find anything useful Googling either.

Any ideas what's wrong or how to fix it please?

TIA
