Last night I tried Por2 1,4 with speed mod on my Athlon 2500+,1 gb DDR, 128 mb geforce 6600gt, xp sp2. Have no problems with it. Works like a charm.

I also try it on my laptop: Core to Duo 2,00 ghz, 2 gb DDR2, 256 mb geforce 8600gs, vista. There is an annoying clipping problem. 3d textures like boxes or chests are flickering when I scroll the screen. Character graphics looks well though. Since there is no option in dxdiag page to close the directdraw acceleration on Vista, I can not do that. And also graphic card's driver don't allow me to close acceleration manually. So, I stuck with this graphics on Vista. It can still pretty playable, but also annoying.

This weekend, my new PC will arrive. I also will try Por2 on it and write the results here. It has Core to Duo 2,95 ghz, 4 gb DDR2, 1 gb geforce gts250 and both XP and Vista on it. So, I will see whether the issue is related with Vista or modern graphics cards. But, I suspect Vista is the real problem here.
