Hello I am playing Dead Space. If i turn on Vsync, FPS is constant on 60 fps. But if i turn if off, FPS go to 89-150. What do you think about it? Its better to turn it on or off? I dont know really if it is better to play with Vsync on... Thanks
Dunno about you but I got insane mouse lag with vsync on at Dead Space. Was forced to turn it off. With some games vsync does not work and you need to turn it off to play game smooth. It does not matter if it's on or off, if game plays smooth. Some people say they cant play without it but I personally it doesn't matter to me.
In case you get screen tearing (http://en.wikipedia.org/wiki/Page_tearing and http://hifi-india.blogspot.com/2006/11/faq-what-is-screen-tearing-and-how-do-i.html), bunbury79, turn it on. Otherwise it doesn't really matter. Btw: VSync is not an image quality setting. Just read the articles at the above links...
If you get mouse lag with vsync on, try reducing maximum pre-rendered frames from the default setting of 3. If you get choppiness where the framerate jumps in steps, enable triple buffering.
I run Dead space with vsync turned off in the options. But, have vsync and triple buffering turned on with D3D Overrider. No mouse lag and buttery smooth now.
