Wondering if anyone else is experiencing the same as me and might have a fix.
The main menu once the game loads there is no issues but the further I go into the menus the slower the mouse gets. So when I click on Solo Campaign the mouse get a bit laggy/slow and the when I start a new campaign and select Male/Female and enter Callsign it doesn't respond at all. Happens with all Menus i.e Main(Fine) -> Options(Slow) -> Video(not responding)
Having the same problems.
Managed to get into the game play, but a couple of menus deep into the game and it's a matter of moving the mouse, then waiting a few seconds to see where the cursor ends up. Really not idea and makes the mission briefing screens and such damn near unusable.

So, yeah, any advice would be appreciated!
