GTA:VC running slowly on PC

Last Updated: January 28, 2024

Question: Why does GTA:VC run so slowly on my system?

Answer: During testing we did find that old Sound and Video card drivers are the main cause of the problem. Make sure that you have installed the latest drivers for the Sound/Video cards. These can be downloaded from the sound/video card manufacturers website.

If the problem persist's then try the following:-

Click on StartClick on RunType in DXDIAGClick on SoundPerform the DirectSound tests. If your Sound card has no hardware buffer then you will be prompted that a software buffer will be used instead.  Press OK.

From within the games video options:Lower the Draw DistanceTurn off Frame Rate limiterTurn off SubtitlesTurn off Wide ScreenSet the games resolution to 640x480 16bit (press enter once you have change it)

Now go into the game's Audio OptionsSet the Audio Hardware device to "Automatically detect Hardware"Turn off Dynamic Accoustic Modelling

If you have changed hardware or installed new drivers for your sound and video cards then try the following below:-

Changing either your video card or soundcard may mean that you get Grand Theft Auto: Vice City into an ""invalid"" settings state for the particular hardware. If you change hardware, to prevent having to un-install and re-install Grand Theft Auto: Vice City, perform the following:

Video card:- delete from the "Grand Theft Auto Vice City/models" directory the files "TXD.DIR" and "TXD.IMG" (if they exist)- delete from the "Grand Theft Auto Vice City/data" directory the file "CAPS.DAT"- delete from the "Documents and Settings/Current logged-in User/My Documents/GTA Vice City User Files" directory the "GTA_VC.SET" file.

Sound Card:- delete from the "Documents and Settings/Current logged-in User/ My Documents/GTA Vice City User Files" directory the "GTA_VC.SET" file.
