SkyGfx is a plugin for GTA III, Vice City, and San Andreas that brings accurate PS2 and Xbox graphics into the PC version.

GTA III and Vice City

From left: default, texblendSwitch switched on, neoCarPipe switched on

Option	Values	Description
replaceDefaultPipeline	0 1	Replaces the default d3d8 RW pipeline by one that is very close to the default Xbox pipeline. Enabling this will fix bugs happening to objects with transparent vertex colors.
texblendSwitch	0 1	Selects which texture blend effect for MatFX environment mapping to use. This option can be toggled in-game through a key set in the texblendSwitchKey option.
texgenSwitch	0 1	Selects which texture coordinate generation method for MatFX environment mapping to use. This option can be toggled in-game through a key set in the texgenSwitchKey option.
dualPass	0 1	Draws almost all transparent geometry in two passes to reduce alpha bugs.
disableBackfaceCulling ( only)	0 1	Disables backface culling like on the PS2 version.
neoCarPipe	0 1	Selects whether to use Xbox-like car reflections; requires d3d9. This option can be toggled in-game through a key set in the neoCarPipeKey option.
envMapSize	*	Sets the size of the reflection map used for Xbox car reflections.
neoRimLightPipe	0 1	Selects whether to use Xbox-like rim lighting on peds; requires d3d9. This option can be toggled in-game through a key set in the neoRimLightKey option.
neoWorldPipe	0 1	Selects whether to use the Xbox-like world pipeline; requires d3d9 to work properly, but there is a fallback for d3d8. This will only have an effect if you actually use objects that have lightmaps. This option can be toggled in-game through a key set in the neoWorldPipeKey option.
neoGlossPipe	0 1	Selects whether to use the Xbox-like gloss pipeline for roads; requires d3d9. This option can be toggled in-game through a key set in the neoGlossPipeKey option.
neoWaterDrops	0 1	Draws Xbox screen water drops.
texblendSwitchKey	*	Switches texblendSwitch (0x76 = F7)
texgenSwitchKey	*	Switches texgenSwitch (0x77 = F8)
neoCarPipeKey	*	Toggles neoCarPipe (0x75 = F6)
neoRimLightKey	*	Toggles neoRimLightPipe (0x74 = F5)
neoWorldPipeKey	*	Toggles neoWorldPipe (0x73 = F4)
neoGlossPipeKey	*	Toggles neoGlossPipe (0x7B = F12)
VCEnvFrame ( only)	0 1	Uses the Vice City MatFX environment map frame where the reflections depend on the camera with PC texture coordinate generation
IIIEnvFrame ( only)	0 1	Uses the GTA III MatFX environment map frame where reflections don't depend on camera angle even with PC texture coordinate generation

If the option has no value at all or its line removed completely, the plugin will not hook the code for that option. A value of 0 still allows the plugin to hook the code so that it can be toggled in-game.
