Hi Diego, thank you for your response.
Well, i don´t think that Lucas-Arts (even if it still exists) would update a game that was made while Windows95 was state-of-art. Anyway, the game got Direct-X support after it was released by Microsoft and it looks like N-Vidia didn´t have a problem to manage this old standard.
I understand if you can´t get this issue analysed well (think you need the game for that), but i must admit that it leaves a little bit of a bad taste on my chose for an Intel graphic accelerator. Sorry.
