i have the copied version of GTA3, and after cracking i found out the game stops at the movies, this because i have a voodoo 3 3000, i downloaded the skipmovies, that worked, but now, when i'm in the game and i walk 3 yards or so the computer jams!!!

now what????? does anyone have a clue? theoretically the game should work.. i have downloaded direct x 8.1 and new videodrivers.. help me!!!!
