[TUTORIAL] How to use Xfire with GTA:Vice City MTA.
1. Go to xfire's folder: C:\Program Files\Xfire
Picture #12. Open up xfire_games.ini with notepad.
Picture #23. Use find (Edit -> Find or CTRL+F) to find "Grand Theft Auto - Vice City".
Picture #24. Remove this line: InGameRenderer=D3D8
Picture #35. Save the file.
Now everything should work, but the ingame chat won't work because we've disabled Xfire's DirectX output to Vice City.. 
Any questions? Feel free to PM me or just ask here!
Cheers!
