Disable V-Sync on XPS 1647

Hi guys, i finally got my XPS 1647, could you tell me how to disable V-sync?
Also, would you reccommend do such thing ?
Thanks.

 

If you're not getting a constant 60fps then disable it as it will instantly drop to 30fps when 60 isn't possible or even 20 if 30 isn't possible. If you have V-sync enabled, your frame rate will only be in factors of your screen refresh rate.

In short, unless it's an old game it's best to leave it turned off. Usually you can turn it off in game settings (it's not usually even ensbled by default) but if that doesn't work then there's an option for it in the "3d settings" section of ATI catalyst.

 

I'd set it to "Off, Unless the Application Specifies" in the CCC, but I think this is the default. You can right click your desktop to access the CCC through the context menu.

In the application itself, I'd pretty much always turn Vsync off, unless it has a special option like triple buffering (since the GPU has a ton of extra memory which triple buffering loves), but even then the main priority is that you have a good framerate. If your framerate drops to 30 often, I'd leave Vsync off then.

Another reason to turn Vsync on is to make your GPU and CPU work less hard (less heat). This is sometimes useful if an old game is giving you for example, 150fps, but even then heat usually isn't a problem.

Edit: I believe V-Sync only locks your framerate to 60, 30, 20 ect. if it is double buffering. If the application only has on or off, it's probably using double buffering. Triple buffering should allow any number of fps and shouldn't hurt your framerate or performance unless there isn't enough GPU memory (and the XPS 1647 has a full GB which is a ton, even for modern games).

 

For most games, you can usually specify a maximum FPS through either the console or a .ini file.
