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)
Installation (apart from menu entries)
What does not
Installer does not fully complete; menu entries are not added but the game can still be started with "wine iw3sp.exe"
Character shadows are missing even when enabled;
Every time the game starts, it tells me that my system configuration has changed (I click Ignore and it works fine from there)
What was not tested
Prior to installing, I had used winetricks to obtain DirectX9, and had changed some of the mouse settings to work with other games.
The game, once installed, appears to run at speeds equaling and surpassing those of Windows XP.
