I have been trying to get halo two to work with my mouse I have a Nvidia gtx 1660 I have 32 gigs of ram ,Ryzen 5 2600x ,Dell keyboard , Hid Complaint mouse, Cd-rom . The issue is that when I am in the game i can't use the mouse at all .. I have tried the Nvidia control panel sync that has not worked . My build of windows is the latest .I have tried shutting off my second monitor as well none off these things seem to work
