If you are not sure whether GPL is fun for you or if you don't have a GPL CD, you can also use the GPL 2004 Demo to play GPL. The GPL 2004 Demo includes the Watkins Glen track including graphics updates, all GPLEA car updates, Ducwolf's sound updates and is patched with the latest official patch version 22.214.171.124, as well as Nigel Pattinson's Carsound patch.
Download and install the GPL 2004 Demo (82,6 MB):
Alternative download link at GPLWORLD:
Download and install Nigel Pattinson's Rasterisers v2.5:
Run the "gplrast_v2.5.exe" and select the path to your 2004 Demo folder.
Go to your 2004 Demo folder and find the "app.ini", open it with Notepad, change "rd3d7v2.dll" to "roglv2.dll" and save. This step is optional. It changes the 3D rasteriser that the game will use.
Tip: The OpenGL v2 Rasteriser ("roglv2.dll") usually delivers better results than the Direct3D v2 Rasteriser ("rd3d7v2.dll"). But on some systems OpenGL v2 does not work with GPL, so you have to use Direct3D v2. Try out what works best on your system.
Download and install the 1967 Update Patch for GPL (67 Patch v1.3 / GPL 1.3 Community Patch): http://gpltd.bcsims.com/?ir=Mods
Important: To use the GPL 2004 Demo with GEM+ and Mods you have to create a new folder "exports" in
(X:\...\SIERRA\gpl) -> (X:\...\SIERRA\gpl\exports).
Then you have a fully functional GPL installation with the Watkins Glen track and all seven cars. The other ten tracks of the CD are missing. But you can use hundreds of tracks available from the GPL Alternative Track Database (GPLTD): http://gpltd.bcsims.com/
You can also install all GPL Mods.
