Not sure where to post this, but aside from the outdated graphics, is anyone experiencing "retarded" mouse movement in the game? I have a Logitech MX510, and find the mouse action just terrible. In the mouse sensitivity settings box, assigning a lower number yields action that feels like molasses. At the higher settings, mouse action is too jerky and unpredictable. I've tried every mouse sensitiviy setting and none work well. I have the latest Vista drivers and the latest Halo2 patch. It's still practically unplayable. The old regular Halo provides much more accurate and predictable mouse control. It's unfortunate that Microsoft/Bungie couldn't do the same with Halo2.
