When I try and play the PC version of Dead Space the mouse is sluggish and unresponsive regardless of how high I set the sensitivity. Is there a fix for this?
Usually this means that vertical sync is set, and you need to unset it, it's one of the most annoying things ever from computers that are slightly behind recommended specs.
Most new GPU's with more then 900Mhz clock speeds will have problems with this game because the GPU proccessing everything way to fast as the game was meant to be played at 30FPS originally. I lowered my clock speeds using MSI afterburner and it helped a lot with the mouse problems (tho the GPU runs at 450mhz the game still goes over 150+ fps in some areas)
