ive played using nvidia's 3d vision on a zalman 22 inch @1680x1050 monitor which is interlaced sys(phenom II 940@3.4 4gigs ddr2 gtx285) like Cairdeas said its not native but nvidia supports it and it works fairly well i got anywhere from 20-30 in town to 30-50 fps outside of town. just upgraded not to long ago to a radeon 5870 cant use nvidia's setup but now im using Tridef with same monitor and projector at times the 3D effect is good but not as good as nvidia's but i think thats b/c ive no clue how to fix the background doubling .. tried everything -.- anyways with the radeon using Tridef on i see 25-35 in town to 40-60 frames outside of town using ether interlaced(zalman) or checkerboard(projector) i havent had the chance to really tri out iz3d's drivers yet hope that helps.
