Suite à consultation sur le site de l´éditeur, le problème semble venir des cartes graphiques geforce MX. Pour les 2MX, on peut essayer de changer de driver. Pour les 4MX, il n´y a malheureusement pas de solution. Pour info, voici le texte qu´on peut trouver sur eidosinteractive.com :
Help! Project IGI does not display a mouse cursor or a gun on my nVidia video card!
This is an issue when using certain versions of the nVidia display drivers, or certain model of Nvidia video cards with Project IGI.
If you have a Geforce MX-series video card such as the Geforce 4 MX or Geforce 2 MX we have no confirmed solution for the problem. Some users report being able to use the older . 1241 nVidia reference drivers with the Geforce 2 MX to solve the problem, but these drivers don´t work with the Geforce 4 MX series. If you have a Geforce 2 MX type video card, try uninstalling your currently installed video driver and installing the older . 1241 version. If you have a Geforce 4 MX series video card, we have no solution to Project IGI not displaying the cursor correctly. We suggest you take the game back to the store for a refund or exchange to some other game.
However, nVidia´s Latest video drivers do work successfully with the Geforce 2, Geforce 3 and non-MX series Geforce 4 video cards and Project IGI.
If you have a non-MX series Geforce card please download and follow the installation instructions to install the 30.82 set from nVidia´s web site which should correct the problem.
