Unrecognized Fatal Exception error

A great amount of copies of GK3 feature a corrupted Day123.brn file on the first of the three CDs, which is the one files are copied from during the installation: this leads to an Unrecognized Fatal Exception error message followed by a game crash.

To avoid this, it is necessary to replace the Day123.brn file in the GK3 Data folder on the hard drive with a copy of the Day123.brn file from CD 2 or CD 3.

Graphics clipping

With ATI Radeon graphics cards, some users might experience some clipping (this is a known issue with this card and happens under any version of Windows).

To avoid this, run Gabriel Knight 3 in software mode. [1]

Game freeze (SIDney, Day 2, 5pm-10pm)

On Day 2, 5pm-10pm playing as Grace, the game freezes up when using SIDney. The freezing happens when the analyzation starts with sound, but graphics don't appear. After a while the sounds stop and the game just stops there showing the red wait icon.

The issue here is a codec conflict with FFDShow. Removing the FFD Show codec pack fixes the problem. If this does not help, try uninstalling any installed big codec packs. [1]
