My mouse moves very slowly in games. I tried Mirror's Edge and Portal, both had the same problem. For example, turning my character around once takes three full drags of the mouse. It's hard to dodge bullets and stuff at that speed The setup: Windows 7 Parallels 8.0.18483 Retina MBP running OS X 10.8 Mountain Lion Smart Mouse off Windows mouse speed set to max Game mouse speed set to max Games installed via Steam This happens both when my VM is set to "Scaled" and "Best for Retina" resolution, probably because I'm running the games in full screen anyway. It happens both on my rMBP built-in display and my external monitor (1600x1200), where I'm trying to run the games. It happens both with my external mouse and trackpad. It also happened on a WinXP VM I tried briefly. I'm trying to run Mirror's Edge at 1280x1024. I do not have Pointer Shadow on. Note the mouse is also very slow in the general Windows interface when the VM is set to "Scaled" resolution. Problem report #24688020.
