The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
Software Renderer mode
Playing and finishing the game
What does not
DirectDraw HAL mode
Some AVI files (not essential to completing game)
Still needs CD 1 in drive even though it is "CD-less" play.
Sometimes the graphics do not work properly, but the game is still playable.
What was not tested
I played the game to the end, but I did not try every subplot.
I used this with the SierraHelp Gabriel Knight 3 Installer, available at http://www.sierrahelp.com/Games/GabrielKnight/GK3Help.html which is designed to make the game compatible with newer versions of Windows. I had to fiddle with the drive configuration of Wine a bit before the installer was able to read my CD drive. Even though the installer is supposed to make it possible to play the game without CDs, I had to keep the first CD in the drive in order to get the game to run (I never had to use the second or third CD after installation).
The game won't work when you start playing - you have to go straight to the Graphics options (the game manual explains how to do this) and change it to Software Renderer mode.
The game does crash often for no apparent reason, so save frequently (this is the main reason I rate this game bronze instead of silver). On two occasions it also ate my most recent save game, but since I had plenty of saves, I just had to backtrack a little more than anticipated. The game could not read AVI files, but they did not seem essential. Personally, I enjoyed playing the game even with all of the technical difficulties.
