Hi I'm absolutely new to wiki things and I recently found a much better way to improve mouse behavior on Dead Space. On : http://pcgamingwiki.com/wiki/Dead_Space The wiki says the mouse lag comes from the 60fps issue. It improves but doesn't really fix the mouse lag properly. I found out two things that actually fixed it for me and I'm now playing properly with 120fps. On my AMD I use RadeonPro and changed the Flip Queue Size to 1 or zero. Also have to go into Mouse options for windows and on the Cursor Options tab, turn OFF "Enhance Mouse Precision". In game vsync turned off. This made the mouse almost perfect, totally playable, massive improvement, almost zero lag. The difference to an nVidia card would probably be to just set the pre-rendered frames to 0 or 1. Should these solutions be posted to the wiki ? Needs more testing ? I really don't know, maybe you guys can figure it out and post there ;)
