Mouse Cursor appearing across screen after using Mouse Look

[Grimgor]

I used to get this, but it went away when I found a fix for my FPS issues. What I ended up having to do was stopping/disabling all Nvidia services.

Some people have found simpler solutions that have worked for them, but unfortunately none of them worked for me. Capping the FPS for Everquest to 60 or your monitor's refresh rate worked for some. Changing low latency mode setting in Nnidia control pannel to ULTRA also worked for some people.
