Start game for the first time, make profile in game first and Do this before you start

You can download it for automatic process here but if you want have time progress in Steam and Steam overlay you must follow there steps:

• In installer choose Upgrade the exiting version
  
  
  
• Specify the main game folder directory
  
  
• choose resolution
  
• Launch the game from steam client everytime
  

Stage 1: XIII.ini setting
We going to ...\XIII - Classic\system
Open the file : "XIII.ini", search and copy the following lines :

• UseTripleBuffering=False
  
• UseVSync=False
  
• ReduceMouseLag=False

Stage 2: Mouse Polling Rate
Another thing that helps, set your Mouse Polling Rate to 250/125HZ(125 great works for me). But maybe it not help you and you can return your standart Polling Rate

If you use "All in one" installer - you don't need this

Go to where your game is installed and find a folder named “System” once there look for a file named “DefUser.ini” when you locate it open it.

Look for these two lines:

DesiredFOV=85.000000
DefaultFOV=85.000000

If you have a monitor with a 16:9 ratio change the number to “100.000000” if your running with a 16:10 try “95.000000” as that seems to work pretty well. Save and exit.

If you use "All in one" installer - you don't need this
Look for a file called “XIII.ini” in the same folder, and open it up. And look for entries named

FullscreenViewportX=
FullscreenViewportY=

I just took information form different sites on the internet and combined with my little experience here.
