GTA3, GTA:VC and GTA:SA works on vista, and works fine for me, no crashes yet (RC1 build 5600) although it wouldnt let me run it Beta 2 because of the drivers wernt finished, i seem to be happy with playing GTA:SA in vista
and the stock drivers seem to be more decent in this release, although they could always be better, but thats microsoft for you...
it is a proper release, close enough to it anyway, RC1, best to get in things early, for testing and development, you mean there waiting for RTM
i would like to see something, but lots of devs seem to get paranoid about there reputation if they release something thats not quite in working condition, i think this idea depreciates the fact that its free and forces people to take this free software for granted, expecting something good when you shouldnt expect anything
