ShadowsFix = 1 ; Dynamic shadows will no longer disappear when going into tunnels, under bridges, etc.
ImproveShadowLOD = 1 ; Increases the level of detail of dynamic shadows. This may negatively affect performance.
AutoScaleShadowsRes = 1 ; Adjusts the specified ShadowsRes based on the user's aspect ratio to maintain quality. This may negatively affect performance.
DisableShadowTextureFilterOnRadeon = 1 ; Disables the forced bilinear filter for the shadow texture on ATI/AMD Radeon GPUs.
ShadowMapTextureFormat = 0 ; Set the texture format for the shadow map texture here. (-1 = Disable patches | 0 = D24S8 (Default, Sharp Shadows) | 1 = INTZ (Soft Shadows) | 2 = DF16 (Radeon Only, Soft Shadows) | 3 = DF24 (Radeon Only, Soft Shadows))
RainDropletsScale = 0.5 ; Adjusts the size of the on-screen rain droplets.
DisableMotionBlur = 0 ; Allows users to disable motion blur without changing registry settings.
LightStreaksEnable = 0 ; Leftover from NFS Underground 2. Enables the light trail effect. Not very visible at higher FPS than 60, but it does make the flares more saturated in color.
BleachByPassEnable = 0 ; (EXPERIMENTAL) Leftover from NFS Underground 2. Enables the "Enhanced Contrast" effect. Requires the IDI_SCREENFILTER_FX shader from Underground 2 to work. If you do not have it, the screen will be blurry!
ForcedGPUVendor = 0x10DE ; Force the GPU PCI VendorID here. This will affect the renderer and video options behavior. (0 = Disabled | 0x10DE = NVIDIA (Default) | 0x1002 = ATI/AMD | 0x8086 = Intel)

[NOSTrail]
FixNOSTrailLength = 1 ; Fixes the NOS trail length for higher FPS.
