What it does: This patch fixes slowdown problems that occur when running Alice on machines equipped with Matrox video cards. Areas that had transparent shafts of light would slow the machine down tremendously when those lighting effects were on the screen. This problem originally occurred on Matrox G400 based video cards, but may appear on any Matrox video card. If you are having this slowdown on another video card, you can try this fix. How to install it: To install the fix, first locate the folder where you installed Alice. Inside that directory is a folder called "base" (default is C:\Program Files\EA GAMES\American McGee's Alice\Base). Just copy the "pak6_update01.pk3" file into the base folder. If you are running Alice, you will need to quit the game and restart it. There should be other files in your base folder, with names like "pak0.pk3" and "pak1_large.pk3". Depending on your installation choices, you may have different pak files in your base folder. To remove the fix, just delete the "pak6_update01.pk3" file and restart Alice.
