FREQUENTLY ASKED QUESTIONS
Q: Why does the "Heat Haze" effect look weird on my ATI graphics card?
A: The Heat Haze effect has been noticed to be corrupt when using ATI 4.x series drivers - this seems cured on 5.x series ATI drivers.
Q: Why does running GRAND THEFT AUTO: San Andreas on my laptop not offer me widescreen screen modes, when the screen on my laptop is a widescreen display?
A: Some laptop widescreen displays are not a standard aspect ratio. GRAND THEFT AUTO: San Andreas only supports 4:3 and 16:9 aspect ratios, and those closely related to them. You may also find some resolutions are not offered as usable at all by GRAND THEFT AUTO : San Andreas because they deviate too much from 4:3 or 16:9 aspect ratios.
Q: Why do the buildings in the world take time to catch up with me when I drive in a fast vehicle in a built up area?
A: Most likely you have disabled the Frame Limiter, or your Hard Drive is not supplying world data at a fast enough rate. Re-enabling the Frame Limiter will help this.
Q: Why am I having difficulty setting up 2 control pads at the same time?
A: GRAND THEFT AUTO: San Andreas can only support one external device.
Q: I cannot complete donuts in the first "Driving School" test.
A: The key setup you are using may not allow the reporting of the 3 necessary keys at the same time, you may have to re-define keys to allow this to be detected correctly.
Q: Why do I get missing and flashing textures in 16 bit graphics modes?
A: GRAND THEFT AUTO: San Andreas was developed specifically for 32 bit screen modes. Although playing in 16 bit modes are supported, this will result in a much poorer experience and the game may not play as intended.
Q: Why do I only hear advertisements when listening to the User Track Player?
A: Check that any shortcuts in the "My Documents\GTA San Andreas User Files\User Tracks" are valid and that they have been scanned using the Scan User Tracks function in the User Track Options menu submenu of the Audio Setup menu. If trying to playback MP3, M4A or WMA tracks you may need to install Windows Media Player, QuickTime or a third party codec pack.
Q: Why does GRAND THEFT AUTO: San Andreas take a long time to start up if I have lots of music files or shortcuts in my User Tracks folder?
A: This occurs when Automatic Media Scan is set to ON in the User Track Options. Turning off the Automatic Media Scan will make loading faster and, in sequential mode, will stop the User Track Player from returning to the first track after the game loads.
Q: Why does GRAND THEFT AUTO: San Andreas always start on the same track when in sequential mode?
A: This occurs when Automatic Media Scan is set to ON in the User Track Options menu. Turning off the Automatic Media Scan will stop the User Track Player from returning to the first track after the game loads.
Q: I don't have a soundcard in my PC (or I don't have the drivers for my soundcard installed) - Can I run GRAND THEFT AUTO: San Andreas on my PC?
A: GRAND THEFT AUTO: San Andreas requires a soundcard to be present, and will refuse to run without one.
Q: Should I install the Radio Stations to Hard Drive whilst installing GRAND THEFT AUTO: San Andreas?
A: Most computers will benefit from playing the Radio Stations from Hard Drive. Exceptions to this would be computers with poor Hard Drive performance - these will benefit from playing the Radio Stations from DVD.
Q: When I installed GRAND THEFT AUTO: San Andreas I selected the full install option to play the Radio Stations from my Hard Drive. Do I still need the GRAND THEFT AUTO: San Andreas DVD in my DVD-ROM drive to play?
A: Yes. You must have the GRAND THEFT AUTO: San Andreas DVD in your DVD-ROM drive at all times.
Q: I don't want to upgrade my finely honed DirectX 8.1 system to DirectX 9; can I still play GRAND THEFT AUTO: San Andreas without DirectX 9?
A: GRAND THEFT AUTO: San Andreas must have DirectX9 installed.
