I'm putting this in the video card forum because I think its more technical than a general gaming question. But I recently turned off v-sync in fallout 3, you have to do this manually by editing your fallout.ini file. This improved the mouse lag tremendously, its a much better feel playing without v-sync and I don't notice any video changes.

My question is, the game seemed to speed up somehow. Its like I'm running faster, but I can't really determine if the game is actually running faster. I just read before turning it off that if you turn it off the game will not run at the right speed and that is why they don't allow you to turn it off through the video settings.

Does anyone know anything about this? Has anyone turned off V-sync? Will turning off v-sync not make the game run in the right timing?

If anyone wants to check it out and never has turned off v-sync, edit the fallout.ini file in your mydocuments folder somewhere, and put where it says ipresentinterval=1 to 0.
 
just force vsync off in the video driver instead if fallout doesn't like it.
 
I play with vsync off because in most cases for me turning it off does not affect image quality in tthe games I play.

You can use program called FRAPS to see if there is a difference between on/off vsync.
